Many control systems employ a brake to hold an axis when the drive is disabled.
Accelnet
Plus Micro Module
drives have digital outputs that can drive MOSFETs for brake control.

Disabling the drive by a hardware or software command starts the following sequence of
events The motor begins to decelerate (at Abort Deceleration rate in position mode or Fast
Stop Ramp rate in velocity mode). At the same time, the Brake/Stop Delay Time count begins.
This allows the drive to slow the motor before applying the brake.
When the motor slows to Brake/Stop Activation Velocity OR the Brake/Stop Delay Time
expires, the brake output activates and PWM Delay Brake/Stop Response Time count begins.
hen response time has passed, the drive’s output stages
are disabled. This delay ensures
the brake has time to lock in before disabling the power section.
