Rules for FW2.4
● The Voltage Sensing Module (VSM) must be connected to a dedicated DRIVE-CLiQ port
of the Control Unit.
● If possible, the CUA31 should be connected at the end of the line.

Notes on the maximum number of drives that can be controlled by a CU320:
•
In addition, the "Safe Standstill" function can be activated and a TM31 connected.
• No function modules must be activated.
1) If a CUA31 is connected as the first module to the Control Unit, then the maximum number is
decreased by one.
