AKD PDMM User Guide | 10.4 Dynamic Braking
When configuring the controlled stop feature, please note the following:
l
If the HW limit switch is active and any of the other CS activated, the only difference will be that in this
case the DRV.DISTO will limit the time before disabling the drive.
l
If the value of DRV.OPMODE of the drive is current mode, the drive will not execute the CS but
instead stop immediately.
l
Set DRV.DISTO to an appropriate value that will allow the motor to decelerate from any velocity to 0
with DRV.DEC. This value must also allow the motor to afterwards remain within VL.FB for CS.TO
consecutively within 0 ± CS.VTHRESH.
The drive issues a fault FF703 (pg 146) in case that the DRV.DISTO counter expires during a controlled
stop procedure.

10.4 Dynamic Braking
Dynamic braking is a method to slow a servo system by dissipating the mechanical energy in a resistor
driven by the motor back EMF. The drive has a built in advanced dynamic braking mode which operates
