Description

The parameter is displayed for MOVI‑C® decentralized drive electronics in the DBC communication variant.

Specifies a predefined configuration for all digital inputs of the inverter. By selecting a predefined configuration, all digital inputs and the operating mode of the fixed setpoints are reconfigured at once.

The setting can be changed only in expert mode (Parameter setting mode parameter in the parameter group Device properties > Basic settings > Permissions).

The following settings are possible:

Meaning

None

No configuration defined. The digital inputs can be configured individually.

CW, CCW, setpoint changeover

With this configuration, the direction of rotation is positive and negative and 2 speed setpoints are set (potentiometer f1/f2).

The digital inputs are configured as follows:

  • DI 01 = Fixed setpoints – positive direction of rotation
  • DI 02 = Fixed setpoints – negative direction of rotation
  • DI 03 = Setpoint changeover potenziometer f1/f2
  • DI 04 = Fault reset

Enable, fixed setpoints

With this configuration, 4 fixed speed setpoints are set. The direction of rotation is specified by the polarity of the fixed setpoint.

The digital inputs are configured as follows:

  • DI 01 = Output stage enable
  • DI 02 = Fixed speed setpoint 20
  • DI 03 = Fixed speed setpoint 21
  • DI 04 = Fault reset

Enable, external fault, setpoint changeover

With this configuration, the direction of rotation is positive and 2 speed setpoints are set (potentiometer f1/f2).

The digital inputs are configured as follows:

  • DI 01 = Output stage enable
  • DI 02 = External fault
  • DI 03 = Setpoint changeover potenziometer f1/f2
  • DI 04 = Fault reset

Motor potentiometer right

With this configuration, the direction of rotation is positive and a stepless speed setpoint is set via motor potentiometer function.

The digital inputs are configured as follows:

  • DI 01 = Output stage enable
  • DI 02 = Motor potentiometer – up
  • DI 03 = Motor potentiometer – down
  • DI 04 = Fault reset

Motor potentiometer left

With this configuration, the direction of rotation is negative and a stepless speed setpoint is set via motor potentiometer function.

The digital inputs are configured as follows:

  • DI 01 = Output stage enable
  • DI 02 = Motor potentiometer – up
  • DI 03 = Motor potentiometer – down
  • DI 04 = Fault reset

CW, CCW, primary frequency

With this configuration, the direction of rotation is positive and negative and the speed setpoint is set via primary frequency input.

The digital inputs are configured as follows:

  • DI 01 = Fixed setpoints – positive direction of rotation
  • DI 02 = Fixed setpoints – negative direction of rotation
  • DI 03 = Primary frequency input
  • DI 04 = Fault reset
