2.8.11.28 Switching command
Depending on the number of motors or selected configuration (2 or 3), the switching command is sent using one
or two logic inputs. The table below lists the possible combinations.

2.8.11.29 Autotuning in multimotor mode
This autotuning can be performed:
• Manually using a logic input when the motor changes
•
Automatically on each first activation of the motor after the inverter is switched on if the parameter [autom
aut-tuning] (AUt) = [Yes] (YES) .
2.8.11.29.1 Motor thermal states in multimotor mode:
The inverter protects each of the three motors separately in that it observes all thermal states and all stop times,
including the switch-off time of the inverter itself.
It is therefore not required to carry out a motor measurement each time the unit is switched on. It is sufficient if at
least one autotuning is performed for each motor.
2.8.11.30 Configuration information output
Via the menu [INPUTS/ OUTPUTS] (I-O-) any configuration or any motor (2 or 3) can be assigned to a logic output
in order to transfer information remotely.
Note:
Due to the changeover of the menu [INPUTS/ OUTPUTS] (I-O-) , these outputs must be assigned in all
configurations, if the information is necessary.
