Efficient Networks S120 manual Rules for FW2.4

Basic information about the drive system 12.10 Rules for wiring with DRIVE-CLiQ

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.
