5.5.8: Brake/Stop Parameters
Enter the following parameters as appropriate.
Parameter Description
Brake/Stop Delay Time Range of accepted values: 0 to 10,000 mSec.
Brake Activation Velocity Range of accepted values: motor-dependent.
PWM Delay Brake/Stop
Response Time
Range of accepted values: 0 to 10,000 mSec.
Brake/Stop Notes
Many control systems employ a brake to hold the axis when the amplifier is disabled. On brake-
equipped systems, disabling the amplifier 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
amplifier 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.
When response time has passed, the amplifier’s output stages are disabled. This delay ensures
the brake has time to lock in before disabling the power section.
This sequence is not available in the current mode of operation. Instead, in current mode, the
amplifier output turns off and the brake output activates immediately when the disable command is
received.
