PWM outputs

Notice

EMC due to PWM

If unshielded cables are used, the permissible limit values for emitted interference due to radiation may be exceeded.

  • Use shielded M12 cables. Integration of the cable shield via pin 5 ("Shield").

Notice

Current-controlled PWM only with inductive loads >1 mH

If the inductance of the load is too low, the output current does not correspond to the specified output current.

  • Only connect inductive loads with an inductance of at least 1 mH.
  • Alternatively, change the operation mode to "Voltage Control", see chapter Basic configuration. You can also connect ohmic loads with "Voltage Control".

The PWM outputs are 5-pin M12 sockets.

The PWM+ and PWM- pins must not be connected to external potentials. Connections with the PWM+ and PWM- of other channels are also not permitted.
