Connection monitoring
The connection monitoring is active in the operating modes 'Manual bus' and
'Manual operation local'. At least one write data record must be sent within 5
seconds, otherwise the motor starter switches off and the signal 'Manual oper-
ation connection abort' is output.
If you do not want to send any commands or control commands, you can, for
example, send an "empty" data record.
Use the empty data record 93 - 'Command' for this purpose. Only the coordina-
tion data is maintained accordingly and the commands are assigned '0'.
Setting the 'Manual local operation' mode for a local control station at the digital
inputs
You can set the 'Manual local operation' mode as follows:
• With a control device (e.g. PC) via the local device interface.
Parameterize the input n – actions 'Motor CLOCKWISE' and 'Motor COUNTER-
CLOCKWISE'.Then disconnect the control device to activate the control system via
the digital inputs. The signaling bit 'Input control' is set.
• With a digital input to which you connect a switch for switching to the operat-
ing mode 'Manual operation local'.
You then have to parameterize this digital input with 'Input n - action' operating mode
'Manual operation local'.
