"Rapid stop" subfunction (only with control via RS485)

  • The "rapid stop" function (apply brake during downward ramp) is introduced for control via RS485. This function is assigned to bit 9 in the control word as virtual terminal in line with the MOVILINK® profile.

1) Recommendation for all bits that are not assigned = "0"

  • When bit 9 is set during the downward ramp, the MOVIMOT® inverter applies the brake (directly via the brake output or via the MOVIMOT® signal relay output) and blocks the output stage.
  • If the motor frequency is less than the stop frequency, the brake is applied, regardless of the status of bit 9.
  • After activating the rapid stop, enable may only be granted again after the drive has come to a standstill.
