Issue B1 3 Commissioning 3.2 Commission modes In the standard version, the MICROMASTER 420 is fitted with the Status Display Panel (SDP) (see Figure 3-2) with which it is possible to use the inverter with the pre-assigned factory settings for a large range of applications. If these factory settings are not suitable, you can adapt them to suit your equipment conditions using the Basic Operator Panel (BOP) (see Figure 3-2) or the Advanced Operator Panel (AOP) (see Figure 3-2).
Issue B1 3.2.1 3 Commissioning Commissioning and Operation with the SDP The SDP has two LEDs on the front which display the current operating status of the inverter (see Section 6.1).
Issue B1 3 Commissioning Basic operation with SDP With the SDP fitted, the following is possible: Ø Start and stopping the motor Ø Reversing the motor Ø Fault Reset Controlling the speed of the motor Connect the terminals as shown in.Figure 3-4. Start/Stop Rev Ack Digital Inputs Analogue Inputs 5.
Issue B1 3.2.2 3 Commissioning Commission Overview with BOP or AOP Prerequisites Mechanical and electrical Installation are completed. Setting the motor frequency DIP Switch 2: Off = 50 Hz / ON = 60 Hz Power ON Quick Commissioning P0010 = 1 See Section 3.2.3 Further Commissioning via P0004 and P0003 An overview of the parameter structure is given in Section 5.3 For a detailed description of the parameter, see the Parameter List. NOTES We recommend the commissioning according this scheme.
Issue B1 3 Commissioning 3.2.2.1 Commissioning with the BOP You can alter parameter values via the BOP. To set parameters on this panel, you must remove the SDP and attach the BOP (see Appendix 0). The BOP features a five-digit, seven-segment display for showing parameter numbers and values, alarm and fault messages and setpoints and actual values. Parameter information cannot be saved via the BOP. Table 3-2 shows the factory default settings for operation via the BOP.
Issue B1 3 Commissioning Buttons on the BOP Panel/Button Function Effects Indicates Status The LCD displays the settings currently used by the converter. Start converter Pressing the button starts the converter. This button is disabled by default. To enable this button set P0700 = 1. OFF1 Stop converter OFF2 Pressing the button causes the motor to come to a standstill at the selected ramp down rate. Disabled by default, to enable set P0700 = 1.
Issue B1 3 Commissioning Changing parameters with the BOP The procedure for changing the value of parameter P0004 is described below. Modifying the value of an indexed parameter is illustrated using the example of P0719. Follow exactly the same procedure to alter other parameters that you wish to set via the BOP.
Issue B1 3 Commissioning NOTES In some cases - when changing parameter values - the display on the BOP shows . This means the inverter is busy with tasks of higher priority. Changing single digits in Parameter values For changing the parameter value rapidly, the single digits of the display can be changed by performing the following actions: Ensure you are in the parameter value changing level (see "Changing parameters with BOP"). 1. Press (function button), which causes the right hand digit to blink.

Issue B1 3 Commissioning 3.3 General operation For a full description of standard and extended parameters, please refer to the Parameter List. NOTICE 1. The inverter does not have a main power switch and is live when the mains supply is connected. It waits, with the output disabled, until the RUN button is pressed or for the presence of a digital ON signal at terminal 5 (rotate right). 2.
Issue B1 3 Commissioning External motor thermal overload protection When operated below rated speed, the cooling effect of fans fitted to the motor shaft is reduced. Consequentially, most motors require de-rating for continuous operation at low frequencies. To ensure that the motors are protected against overheating under these conditions, a PTC temperature sensor must be fitted to the motor and connected to the inverter control terminals. P0601 must also be set to 1.

Issue B1 9 Electro-magnetic compatibility 9.1 Electro-magnetic compatibility (EMC) All manufacturers / assemblers of electrical apparatus which “performs a complete intrinsic function and is placed on the market as a single unit intended for the end user” must comply with the EMC directive 89/336/EEC. There are three routes for the manufacturer/assembler to demonstrate compliance: 9.1.
Issue B1 9.1.4 9 Electro-magnetic compatibility EMC Directive Compliance with Imminent Harmonics Regulations From 1st January 2001 all electrical apparatus covered by the EMC Directive will have to comply with EN 61000-3-2 "Limits for harmonic current emissions (equipment input ≤ 16 A per phase)".
Issue B1 9 Electro-magnetic compatibility 9.1.5 Classification of EMC performance Three General classes of EMC performance are available as detailed below: Class 1: General Industrial Compliance with the EMC Product Standard for Power Drive Systems EN 68100-3 for use in Second Environment (Industrial) and Restricted Distribution.
Issue B1 9 Electro-magnetic compatibility Class 3: Filtered - for residential, commercial and light industry This level of performance will allow the manufacturer / assembler to self-certify compliance of their apparatus with the EMC directive for the residential, commercial and light industrial environment as regards the EMC performance characteristics of the power drive system. Performance limits are as specified in the generic emission and immunity standards EN 50081-1 and EN 50082-1.
