8.9.2.11 Setting error if no communication present
You can use this parameter to set whether it is an error if the device does
not receive any messages via the CAN bus or if there are no other CAN bus
participants in the same parallel operation group.
To set the parameters, proceed as follows:
1. Go to Settings > Parameters > Parallel operation > Error if no com-
munication present .
2. Select the option you want.
3. Press the Accept button to save the modified parameter.
8.9.2.12 Setting behavior if no communication present
You can use this parameter to set how the voltage regulator behaves if
communication via the CAN bus is not possible.
The setting for this parameter is only effective if you have selected the Error
option for the Error if no communication present parameter.
You can select the following options:
Option Description
Independent regula-
tion The device switches from parallel operation to normal auto-
matic voltage regulation
Auto blocking Automatic voltage regulation is blocked.
cosφ interpolation Continuation of parallel operation with interpolated values
(only possible with circulating reactive current parallel oper-
ation method)
Power factor Circulating reactive current minimization without CAN bus
communication [

ation method
Table 34: Behavior if no communication present
To set the behavior, proceed as follows:
1. Go to Settings > Parameters > Parallel operation > Behavior if no
communication present .
2. Select the desired option.
3. Press the Accept button to save the modified parameter.
8.9.2.13 Setting delay time for parallel operation error messages
You can use this parameter to set the delay time for a parallel operation er-
ror message so that brief fault messages are not received if the motor-drive
units involved in the parallel operation have different runtimes.
