Note
Wiring to a digital input of the Control Unit
Output terminal X21.1 must be wired to a digital input on the CU. The drives supplied with
power from the Smart Line Module have to use this signal as a ready signal. This ensures
that a pulse enable can only be issued for the drives (motor or generator operation) when the
infeed is ready.
If interconnection with a digital input on the CU is not possible, the signal must be evaluated
by a higher-level control system instead. It is not permissible that the control system sets the
drives to ready until the infeed "Ready" signal is present.
