For an inverter with PROFIBUS or PROFINET interface, operation can be switched over
using digital input DI 3. The motor is either switched on and off via the fieldbus – or operated
in the jog mode via its digital inputs.
For a control command at the respective digital input, the motor rotates with ±150 rpm. The
same ramp-up and ramp-down times as described above apply.
