2 Modules 2.2.2 Installation of technology units in the SK 300E and SK 750E The 6 cover plate screws must be removed to install the technology box. Note the earthing cable, which can be plugged into the plate. Ensure this cable is connected when installing the technology box to guarantee complete earthing. Maximum protection class IP66 is only guaranteed if the seal is used and the 6 screws are secured correctly to create a tight seal.
NORDAC InterBus Operating Manual 3 Bus configuration An InterBus network consists of a maximum of 256 subscribers and is based on a ring topology. The number of subscribers is dependent on the number of IO's. With a useful data length of 3 words, it is possible to connect 85 devices with the NORDAC 700E. 3.1 Laying the bus cables In an industrial environment the correct installation of the Bus system is particularly important in order to reduce potential interference.
4 The InterBus protocol 4 The InterBus protocol InterBus works with a summation frame protocol. Each subscriber has a fixed data length. Note: If the mode switch is permanently set (Position 1 – 3), the software/parameter settings are ineffective! 4.1 Drive profile If the drive is to be operated as per DRIVECOM 21 profile, the frequency inverter can be configured via Parameter 551. This also changes the ID of the subscriber. Drive profile On (P551 = 1) ID[7..
NORDAC InterBus Operating Manual 4.3 Transmission times The cycle time is dependent on the number of words to be transmitted. It increases linearly with increasing word quantity. The cycle time in dependence on the total word length is shown in the diagram for a transmission rate of 500kBit/s. The number of inverters shown is based on a 3 word data length. t /[ms] 14 7,2 Words in total frame 1 14 128 (equiv. to 42 FI) 256 (equiv.
5 Settings and displays 5 Frequency inverters – settings and displays 5.1 Frequency inverter bus parameters To operate the inverter with the InterBus protocol, the bus must be connected to the master and some settings have to be made on the frequency inverter. With InterBus protocol, the inverter parameters are mapped in the range 2000hex to 23E7hex (= 8192dec to 9191dec), i.e. when parameterisation is carried out via the bus, the parameter numbers must be added to the value 2000hex (e.g.

6 Data transmission 6 Data transmission 6.1 Process data (PZD) The inverter with InterBus technology unit is a slave on the InterBus. The process date are setpoint and actual data that need to be transmitted rapidly, e.g. motor speed. In the process data area (PZD), control words and setpoints are transferred from the master to the slave and in return, status words and actual values are sent from the slave to the master. 6.1.
NORDAC InterBus Operating Manual 6.1.2 The status word (ZSW) The status word (ZSW) is the first word transferred to the inverter in the process data area in the inverter response telegram.
6 Data transmission 6.1.3 The setpoint 1 (SW1) The function of the 1st setpoint is set in parameter P546. The following options are available: Setpoint frequency (16 Bit) The setpoint frequency in setpoint 1 is transferred as a 16 Bit value as standard. Setpoint 1 is transferred to the inverter as the second word in the process data area in the order telegram.
NORDAC InterBus Operating Manual 6.1.4 Second and third setpoint (SW2/3) If the PPO type 2 or 4 is used, in addition to setpoint 1, a 2nd setpoint can be transferred in word PZD4 and a 3rd setpoint in PZD3. PZD1 STW PZD2 SW1 PZD3 SW3 PZD3 SW2 A third setpoint value can only be transferred if a 32 Bit setpoint value is not transferred in the first setpoint. PZD1 PZD2 PZD3 PZD3 STW SW1 SW2 The second and third setpoints are always 16 Bits.
6 Data transmission With the setting ‘Digital I/O status’, the states of the control terminals and the relay (MFR) can be transferred: Bit Bit 0 -5 Bit 6-11 for Posicon special extension unit Bit 6 for encoder special extension unit Bit 12 -15 Status Digital input 1-6 Digital input 7-12 Digital input 7 Multifunctional relay 1-4 With the settings ‘Actual position’ and ‘Setpoint position’, the actual absolute position is transferred.

6 Data transmission 6.3 Parameter orders with Compact PCP Parameter data are divided into individual parameter blocks and transmitted in sequence. This is implemented by the PCP (Peripherals Communication Protocol). The transmission of a parameter can therefore take several bus cycles. This is slower in comparison to process data transmission. The IBS technology unit has an integrated 1 word PCP channel. The PCP is implemented in the Compact PCP version.
NORDAC InterBus Operating Manual 6.4 Drive profile DRIVECOM 21 If the drive profile parameter (P551) is switched on in the frequency inverter, the device supports the profile as per DRIVECOM 21 (speed profile). The mandatory objects are implemented (see overview). The profile is only valid in parameter set 1. 6.4.

NORDAC InterBus Operating Manual 7 Example telegrams Various example telegrams are shown below to clarify the control and parameterisation of the frequency inverter with InterBus. 7.1 Switch-on block → Standby A frequency inverter must be switched from the "Switch-on block" status (STW Bit 0 – 0), which is active when the device is switched on, to the "Standby" status (STW Bit 0 = 1). Parameter set 1 is valid. Only the PZD channel is evaluated.
7 Example telegrams 7.2 Enable with 50% setpoint A frequency inverter in the "Standby" status must be enabled for clockwise rotation with 50% setpoint. The last response telegram was received as follows in the controller.
NORDAC InterBus Operating Manual 7.3 Writing a parameter When transferring parameter orders, it must be taken into account that the slave does not immediately respond to orders in the parameter channel of the master telegram, but a positive response can be delayed by one or more communication cycles. The master must therefore repeat the required order until the corresponding slave response is received.
