Frequency Inverter Control
10.1 Control via Contacts/Remote-Contacts
In the operation mode "Control via Contacts" or "Control via Remote-Contacts" (Parameter
Lo-
cal/Remote
412 = 0 or 2), the frequency inverter is controlled directly via the digital inputs or via the
individual bits of the virtual signals in the
Control Word. The meaning of these inputs is described in
the operating instructions of the frequency inverter.

Note
:
If operation mode "Control via Remote-Contacts" is used, then the Controller Release on STOA (Ter-
minal X11.3) and STOB (Terminal X13.3) must be switched on and bit 0 of the Control Word must be
set in order to start the drive.
The operation modes "Control via Contacts" and "Control via Remote-Contacts" only support the
mode of operation "velocity mode".
Note
:
The frequency inverters support an external 24 V voltage supply for the control electronics of the fre-
quency inverter. Communication between the controlling device (PLC) and the frequency inverter is
still possible even when the mains supply has been switched off.
Bit 4 "Voltage enabled" in the Status Word indicates the current status of the mains supply.
Bit 4 "Voltage enabled" = 0 signals "no mains supply" and that starting the drive is not possible.
Bit 4 "Voltage enabled" = 1 signals "mains supply switched on" and drive ready for starting.
