Short Description Standstill Threshold

Description

The VEL0 (Velocity "0") parameter defines the velocity threshold (in RPM) for the standstill signal.

The standstill signal is required for the following functions:

  1. Standstill signal in the status register DRVSTAT.
  2. If the brake is configured (MBRAKE=1), then, if the output stage is disabled, first of all the velocity is reduced to 0, and the brake is only applied after the velocity has fallen below the standstill threshold.
  3. If the ACTFAULT option is activated (active braking in the event of a fault), or the STOPMODE option (active braking if the output stage is disabled), then the standstill threshold defines the velocity below which the output stage will actually be disabled.
  4. The minimum VEL0 value is changed from 0 rpm to 1 rpm in FW >= 2.14
