12.10.2 Rules for different firmware releases
Rules for FW2.1
● Only one Active Line Module can be connected to a Control Unit.
● The default sampling times must not be changed.
● A Double Motor Module must not be operated as a single drive.
● Mixed operation of servo and vector V/f is not permitted.
● The Active Line Module and the Motor Modules must be connected to separate DRIVE-
CLiQ lines, both for vector and for servo.
