Short Description

Service Operation (STEP Command)

Description

The STEP command is used to implement a service function through the operating mode “digital velocity control” (OPMODE=0). The command can be used in the following forms.

  1. STEP The command provides the present settings for the service function.
  2. STEP T1 V1 A digital setpoint V1 (RPM) is provided for time T1 (in msec). After T1 has elapsed, the digital setpoint is set to 0.
  3. STEP T1 V1 T2 V2 A digital setpoint V1 (RPM) is provided for time T1 (in msec). After T1 has elapsed, a digital setpoint V2 (RPM) is provided for time T2 (in msec). After T2 has elapsed, the T1/V1 cycle starts again.

This command can be used to create an endless reversing operation.
e.g. STEP 1000 500 1000 -500

The service operation can always be cancelled by using the STOP command. The “digital velocity control” operating mode is a precondition for implementing the STEP command.
