5 Commissioning 5.2 Commissioning of the frequency inverter The SK 2xxE inverter series can be commissioned in various ways: a) For simple applications (e.g conveyor applications) by means of the DIP switches integrated into the frequency inverter (internal) and the (externally accessible) potentiometers (SK 2x5E only). In this configuration the plug-in EEPROM is not required. b) By adaptation of parameters using software via the ParameterBox (SK CSX-3H or SK PAR-3H) or NORD CON PC - supported software.
SK 200E Manual for frequency inverters 5.2.2 Configuration Changes to individual parameters are usually necessary for operation. However configuration can be carried out to a limited extent with the by means of the integrated 8-pole DIP switch (S1). NOTE Mixing of DIP switch configuration and (software) parameterisation should be avoided. 5.2.2.1 Parameterisation The use of a ParameterBox (SK CSX-3H / SK PAR) or NORD CON software is necessary to change the parameters.
5 Commissioning 5.2.2.2 DIP switch configuration Inverter (S1) The DIP switches provide the possibility of carrying out commissioning without additional control units. Further settings are made using the potentiometer on the top of the frequency inverter (P1 / P2, SK 2x5E only). As supplied, all DIP switches are at the "0" (Off) position, which corresponds to control via the digital inputs. The frequency setpoint is changed with P1 and P2 (P1 / P2, SK 2x5E only). No.

The PTC input must be bypassed, if a motor with PTC is not available. Parameter (P428) must be changed if an automatic startup with "Mains On" is required. 5.2.3.1 SK 2x0E - Minimal Configuration The frequency inverter provides all the necessary low voltages (24VDC / 10V DC).
SK 200E Manual for frequency inverters Minimal configuration with options In order to implement completely autonomous operation (i.e. independent of control cables etc.) a potentiometer unit (SK CU4-POT) is required. In combination with an integrated mains unit (SK CU4-…-24V) a solution can be implemented with an SK 2x5E which uses only one mains cable (1~ / 3~ according to the version), and a suitable speed and direction control can be ensured (See connection example below).
5 Commissioning Test operation The frequency inverter versions SK 2x0E in size 4 and SK 2x5E, may be commissioned without any auxiliary equipment for testing purposes. For this, after electrical connection has been made (See Sections 2.7 and 2.8) DIP switches S1: 1 to 5 (Section 5.2.2.2) of the frequency inverter must be set to the position "0" ("OFF") and the digital input DIN1 (Terminal 21) must be permanently wired to the 24 V control voltage.
SK 200E Manual for frequency inverters 5.3 KTY84-130 connection The current vector control of the SK 2xxE series can be further optimised by the use of a KTY84-130 temperature sensor (Rth(0°C)=500, Rth(100°C)=1000). By continuous measurement of the motor temperature, the highest precision of regulation by the frequency inverter and the associated optimum speed precision of the motor is achieved at all times.

SK 200E Manual for frequency inverters 5.4 AS Interface 5.4.1 The bus system The Actuator -Sensor Interface (AS Interface) is a bus system for the lower field bus level. The transfer principle is a single-master system with cyclical polling. Up to 31 standard slaves (or 62 A/B slaves in the extended address range) can be operated on an unshielded two-wire cable up to 100m long and in any network structure (tree / linear / star). For the AS Interface, since the Complete Specification V2.
5 Commissioning 5.4.2 Features The SK 22xE and SK 23xE frequency inverter versions provide an integrated AS interface as standard. Therefore, these devices can be directly integrated into an AS interface network. Only the adaptation of various frequency inverter functions (Dip switches or parameters), addressing and the correct connection of the power supply, BUS, sensor and actuator cables needs to be carried out.
SK 200E Manual for frequency inverters 5.4.3 Bus structure and technology The AS interface network can be set up in any desired form. Linear, star, ring and tree structures are possible. An existing network can be expanded by further slaves at any time. Up to 31 standard slaves (i.e. a maximum of 124 binary sensors and 124 binary actuators) or 62 A/B slaves (i.e. a maximum of 248 binary sensors and 248 binary actuators) can be connected to an AS interface network or an AS interface master.
5 Commissioning 5.4.4 Commissioning of the AS Interface Connection Connection of the AS interface cable is made via terminals 85/85 of the terminal block and can optionally be made to an appropriately labelled M12 flange plug contact (yellow) Details of the connection terminals are explained in Section 2.8.2.

SK 200E Manual for frequency inverters 9.2 Process controller The process controller is a PI controller, with which it is possible to limit the controller output. In addition, the output is standardised to a percentage of a master setpoint value. This provides the possibility of controlling an upstream drive unit with the master setpoint value and adjusting it with the PI controller. Ramp time PI setpoint P416 Master setpoint value a) Analog input 1 (P400[-03]=2) Min.

SK 200E Manual for frequency inverters 9.3 Electromagnetic compatibility As of July 2007, all electrical equipment which has an intrinsic, independent function and which is sold as an individual unit for end users, must comply with Directive 2004/108/EEC (formerly Directive EEC/89/336).. There are three different ways for manufacturers to display compliance with this directive: 1.
9 Additional Information 9.4 EMC limit value classes Please note that these limit value classes are only reached if the standard pulse frequency (6kHz) is being used and the length of the shielded motor cable does not exceed the permissible limits. In addition, it is essential to use wiring suitable for EMC. The motor cable shielding must be applied on both sides (frequency inverter shield angle and the metal motor terminal box). Jumper position Device type Max.
SK 200E Manual for frequency inverters 9.5 Reduced output power The SK 2xxE frequency inverter series is designed to handle certain overload situations. For example, 1.5x overcurrent can be used for 60 sec. For approx. 3.5 sec a 2x overcurrent is possible.
9 Additional Information 9.5.2 Reduced overcurrent due to time The possible overload capacity changes depending on the duration of an overload. Several values are cited in this table. If one of these limiting values is reached, the frequency inverter must have sufficient time (with low utilisation or without load) in order to regenerate itself. If operated repeatedly in the overload region at short intervals, the limiting values stated in the tables are reduced.
SK 200E Manual for frequency inverters 9.5.3 Reduced overcurrent due to output frequency To protect the power unit at low output frequencies (<4.5Hz) a monitoring system is provided, with which the temperature of the IGBTs (integrated gate bipolar transistor) due to high current is determined. In order to prevent current being taken off above the limit shown in the diagram, a pulse switch-off (P537) with a variable limit is introduced. At a standstill, with 6kHz pulse frequency, current above 1.
9 Additional Information 9.5.4 Reduced output current due to mains voltage The devices are designed with thermal characteristics according to the rated output currents. Accordingly, for lower mains voltages, higher currents cannot be taken off in order to maintain the stated power constant. For mains voltages above 400v there is a reduction of the permissible continuous output current, which is inversely proportional to the mains voltage, in order to compensate for the increased switching losses.
SK 200E Manual for frequency inverters 9.6 Operation with FI circuit breakers With SK 2xxE frequency inverters (except 115V devices), leakage currents of > 40mA are to be expected if the mains filter is active. If possible, an FI circuit breaker for the protection of personnel should not be used. If the frequency inverter is to be used with an FI circuit breaker for the protection of personnel, the leakage currents to earth must be reduced to 10 - 20 mA by means of jumpers.
9 Additional Information Addressing If several frequency inverters are connected to a system bus, these devices must be assigned with unique addresses. For preference, this is done via the DIP switch S1 on the underside of the SK2xxE (Section 5.2.2.2). For the use of CANopen absolute encoders, the encoders must be assigned to the relevant FI via the node ID.
SK 200E Manual for frequency inverters 9.8 Energy efficiency NORD frequency inverters have a low power consumption and are therefore highly efficient. In addition, by means of "Automatic flux adaptation" (parameter (P219)), the SK 2xxE provides a facility for improving the energy efficiency of the entire drive unit (especially in applications with partial loads).
9 Additional Information 9.9 Motor data - characteristic curves 9.9.1 50Hz characteristic curve ( Adjustment range 01:10:00) a) 115V / 230V frequency inverter For 50Hz operation, the motor can be used at the rated torque up to its rating point of 50Hz/230V. In spite of this, operation above 50Hz is possible, however the output torque reduces in a non-linear manner (see following diagram).
SK 200E Manual for frequency inverters b) 400V frequency inverter For 50Hz operation, the motor can be used at the rated torque up to its rating point of 50Hz/400V. In spite of this, operation above 50Hz is possible, however the output torque reduces in a non-linear manner (see following diagram). Above the rating point the motor enters its field reduction range, as with an increase of frequency above 50Hz, the voltage can not be increased above 400V. Due to the mains voltage, only max. 400V are available.
9 Additional Information 9.9.2 87Hz characteristic curve (only 400V devices) ( Adjustment range 01:17:00) The 87Hz characteristic curve is an extension of the speed adjustment range with a constant rated torque for the motor.
SK 200E Manual for frequency inverters 9.9.3 100Hz characteristic curve (only 400V devices) ( Adjustment range 1:20) For a large speed adjustment range up to a ratio of 1:20 an operating point of 100Hz/400V may be selected. For this, special motor data is necessary (see below), which deviates from the normal 50Hz data. Care must be taken that a constant torque is produced over the entire adjustment range, however this is smaller than the rated torque for 50Hz operation.
9 Additional Information 9.10 Standardisation of setpoint/actual values The following table contains details for the standardisation of typical setpoint and actual values. This information relates to the parameters (P400), (P418), (P543), (P546), (P740) or (P741).
SK 200E Manual for frequency inverters 9.11 Definition of setpoint and actual value processing (frequencies) The frequencies used in parameters (P502) and (P543) are processed in various ways according the following table.

9 Additional Information 9.12 Maintenance and servicing information 9.12.1 Maintenance Instructions In normal use, NORDAC SK 2xxE frequency inverters are maintenance free. Please note the "General data" in Section 8.1. Dusty environments If the frequency converter is being used in a dusty environment, the cooling-vane surfaces should be regularly cleaned with compressed air. If air intake filters have been built into the control cabinet, then these should also be regularly cleaned or replaced.

Documentation, Supplement to BU 0200 – AS-i, SK 225E, SK 235E Connection example: Variant 2 – Use of the digital output DO1 (Terminal 1) as a "power source". The digital output of the frequency inverter is protected against short circuit. A short circuit in a peripheral device connected to this output will therefore not cause damage to the frequency inverter. Therefore it is recommended that any actuators are supplied via the digital output.

Documentation – DIP-Switch (S1), SK2xxE NOTICE Incompatibility Due to the function change, there is an incompatibility with devices manufactured at an earlier date. This must be taken into account for changes to the DIP switch positions. The contents of Page 151 of BU0200 - Version 4411 will be replaced with the following content: 5.2.2.2 Inverter DIP switch configuration (S1) The DIP switches provide the possibility of carrying out commissioning without additional control units.
Documentation – DIP-Switch (S1), SK2xxE Explanation of the changed function: The frequency inverter is equipped with an internal EEPROM and a plug-in EEPROM ("Memory Module") which operates in parallel to this for the storage and management of parameter data. The data from the device are managed in parallel on both devices, so that a safe and rapid exchange of parameter settings in the device is possible for commissioning or in case of service.
