Kinco FD5 Series - 6.8.3 Stop Mode Control

Kinco FD5 AC series servo driver user manual
Chatper 6 Operation mode introduction
89
When the stop enable command is written in the control word, the control of the holding brake is related to the set quick stop
mode.
When the quick stop mode is 0 (uncontrolled stop), the drive will automatically switch to the immediate speed mode (-3) and set
the target speed to 0 internally to make the motor stop as soon as possible, in the uncontrolled stop mode After the drive changes
the target speed, it will immediately cut off the 24V power supply to the brake. After the brake power is cut off and lasts for a
certain period of time (the brake delay), the drive actually enters the disabled state, and the motor is powered off and the shaft is
released.

When the quick stop mode is 2 (quick stop deceleration stop), the drive automatically switches to speed mode (3) and decelerates
to stop at quick stop deceleration (60850020) when it is disabled. Only after the drive judges that the effective target speed is zero
speed , the drive will cut off the 24V brake power supply. After the brake power supply has been cut off for a certain period of
time (the brake delay time), the drive will enter the disabled state, and the motor will be disconnected from the power supply.

6.8.3 Stop Mode Control
The motor can be stopped in the following ways:
0, uncontrolled stop; the motor will directly cut off the power to loosen the shaft without any control, and stop naturally by friction.
After the stop is completed, the motor loosens the shaft. The uncontrolled stop mode has a longer deceleration time, but less
mechanical impact.
1. The curve stops; it stops according to the trapezoidal deceleration (60840020) curve, and the motor loosens the shaft after the
stop is completed.
2. Quick stop deceleration stop; stop according to the quick stop deceleration (60850020), and the motor loosens the shaft after the
stop is completed.
Note
After the motor accessory is set to 1, the load drop will be disabled, and the brake delay can be
appropriately increased. If adjusting the brake delay cannot improve the problem, check whether
the brake torque meets the load demand.
