Operation mode selection (Pr. 79)
4.2.33 Operation mode selection (Pr. 79)
Pr. 79 "operation mode selection"
Used to select the operation mode of the inverter.
The inverter can be run from the control panel or
parameter unit (PU operation), with external
signals (external operation), by combination of PU
operation and external operation (external/PU
combined operation), or by computer link
operation.
When power is switched on (factory setting), the external operation mode is selected.
