6.3.1
Factory setting of the inverter control
Switching the motor on and off
The inverter is set in the factory so that after it has been switched on, the motor accelerates
up to its speed setpoint in 10 seconds (referred to 1500 rpm). After it has been switched off,
the motor also brakes with a ramp-down time of 10 seconds.

Minimum and maximum speed
Minimum and maximum speed
●
Minimum speed - factory setting 0 [rpm]
The minimum speed is the lowest speed of the motor independent of the speed setpoint.
A minimum speed > 0 is, for example, useful for fans or pumps.
●
Maximum speed - factory setting 1500 [rpm]
The inverter limits the motor speed to the maximum speed.
Operate the inverter with the factory setting
We recommend that you execute quick commissioning. For quick commissioning, you must
adapt the inverter to the connected motor by setting the motor data in the inverter.
In basic applications with a standard induction motor, you can attempt to operate the drive
with a rated power of < 18.5 kW without carry out an additional commissioning steps. Check
whether the control quality of the drive without commissioning is adequate for the
requirements of the application.
