Binary controller

The behavior of the drive unit depends on the following factors:

  • Selected configuration of the digital inputs.
  • Status of digital inputs.

The following table describes the control functions in conjunction with the predefined configurations of the digital inputs.

The following configurations of the digital inputs are available:

No.

Configuration of the digital inputs

Description

0

User-defined configuration

  • The individual digital inputs can be configured separately.
  • The operating mode of the fixed setpoint processing can be freely configured.
