Motor Brake Control
As default Relay 2 is used to control the motors electromechanical brake, the Relay is rated for 250VAC, 30VDC, 5A.
The drive has 2 methods of motor brake control:
When Brake Apply Speed (P5-03) = 0 drive will go through Zero Speed Hold (P9-22) before applying the brake.
When Brake Apply Speed (P5-03) > 0 drive will apply brake as soon as SPEED <= BRAKE APPLY SPEED (P5-03) and will skip Zero Speed Holding time.
Parameter Number | Parameter Name | Units | Default | Available Settings | Access | Change During Run | Scaling | Size (Bytes) | CAN Register | CAN Sub Index | Modbus Register |
---|---|---|---|---|---|---|---|---|---|---|---|
P5-01 | Brake Release Time | sec | 0.5s | 0.0 ... 5.0s | RW | Y | 1 = 0.1 s | 1 | 21F5h | 0 | 501 |
P5-02 | Brake Apply Delay | sec | 0.2s | 0.0 ... 5.0s | RW | Y | 1 = 0.1 s | 1 | 21F6h | 0 | 502 |
P5-03 | Brake Apply Speed | Hz / rpm / ft/s / m/s | 0.00 | 0.00 ... P8-01 | RW | Y | 1 = 0.01Hz | 2 | 21F7h | 0 | 503 |
Sets the delay time, following the contactor Delay time (P3-01) in which it takes for the motor brake to be released (Relay 2) and then drive output frequency ramps up.
Sets the delay time, for the motor brake to apply (Relay 2 to open).
Sets the speed at which the drive will open Relay 2 and apply the motor brake.
