4.9.20 Voltage Sensing Module for determining the actual motor speed and the phase
angle (option K51)
Voltage recording module VSM10 is used to operate a permanent-field synchronous
machine without encoder with the requirement for switching to a machine which is already
running (capture function).
The terminals on the Voltage Sensing Module (-B51) are pre-assigned in the factory and
must not be changed by the customer.
To commission the function, the permanent-field synchronous machine without encoder
must be input and "Flying restart" activated with p1200.
4.9.21 Customer terminal block extension (option G61)
Description
A TM31 interface module (customer terminal block –A60) is already installed in standard. A
second module (–A61) provides the following additional digital and analog inputs/outputs in
the drive system:
● 8 digital inputs
● 4 bidirectional digital inputs/outputs
● 2 relay outputs with changeover contact
● 2 analog inputs
● 2 analog outputs
● 1 temperature sensor input (KTY84-130/PTC)
The second TM31 must be installed on the system side. Default settings are not provided.
