Availability of option
This option is available for the following S120 Cabinet Modules:
● Motor Modules
Description
The VSM10 Voltage Sensing Module is used to sense the voltage characteristic on the
motor side, so that the following functions can be implemented:
● Operation of a permanent-magnet synchronous motor without encoder with the
requirement to be able to connect to a motor that is already running (flying restart
function).
● Fast flying restart of large induction motors: The time for the demagnetization of the motor
is eliminated as a result of the voltage sensing.
The terminals on the Voltage Sensing Module (-T1-B51) are pre-assigned in the factory and
must not be changed by the customer.
When operating a permanent-magnet synchronous motor without encoder, the "Flying
restart" function must be activated with p1200.
