Switching the motor on and off in the jog mode
Figure 5-4
In the case of inverters with a PROFIBUS or PROFINET interface, operation can be switched
via digital input DI 3. The motor is either switched on and off via PROFIBUS – or operated in
jog mode via its digital inputs.
When a control command is received at the respective digital input, the motor rotates at ±150
rpm. The same ramp-up and ramp-down times as described above apply.
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.
