relevant Active Line Module / Motor Module only if the DRIVE-CLiQ clock cycle matches
the current controller clock cycle of the Active Line Module / Motor Module.
– Max. 5 servo axes for standard settings of cycle times (monitoring cycle: 12 ms;
application cycle: 125 µs).
– Max. 4 servo axes for standard settings on one line.
– Max. 2 vector axes for standard settings of cycle times (monitoring cycle: 12 ms;
application cycle: 250 µs).
– A Double Motor Module, DMC20, TM54F, and CUA32 each correspond to two DRIVE-
CLiQ nodes.
– TM54F must not be connected to a Motor Module via DRIVE-CLiQ.
