Converter interfaces
The inputs and outputs and the fieldbus interface of the converter have specific functions
when set to the factory settings.
Switching the motor on and off
The converter is set in the factory as follows:
• For a converter with PROFINET communication, the motor is switched on and off via the
fieldbus.
• After the ON command, the motor accelerates with a ramp-up time of 1 s (referred to the
maximum speed) to its speed setpoint.
• After the OFF1 command, the motor brakes down to standstill with 1 s ramp-down time.
• The motor direction of rotation reverses with the reversing command.
The ramp-up and ramp-down times define the maximum motor acceleration when the speed
setpoint changes. The ramp-up and ramp-down times are derived from the time between
motor standstill and the maximum speed, or between the maximum speed and motor
standstill.
Traversing the motor in JOG mode
For a converter with PROFINET communication, the motor is operated in JOG mode via the
fieldbus.
When a control command is received, the motor rotates at ±150 rpm. The same ramp-up and
ramp-down times as described above apply.
