Siemens SINAMICS S120 Function Manual page 277

VSM parameters are independent of the data set model of the SINAMICS S120 drive. A
maximum of two VSMs are permitted for each Vector drive object.
Note
Use of 2 Voltage Sensing Modules
If two Voltage Sensing Modules are connected to one Motor Module, the 1st Voltage Sensing
Module (p0151[0]) is used to measure the line voltage (p3801). The motor voltage is measured
(p1200) with the 2nd Voltage Sensing Module.
Identification via LED and firmware version
The identification of the Voltage Sensing Module via LED is activated via parameter p0154.
When p0154 = 1, the LED RDY on the relevant VSM flashes green/orange or red/orange at a
frequency of 2 Hz. The firmware version of the VSM can be displayed using parameter
p0158[0,1] on the Vector drive object.
