terminal control, the motor is stopped naturally. The law of motion is related to the load inertia.
4.4 Motor forward/reverse control (F/R)
The direction of motor operation can be controlled by controlling the connection of terminal F/R to terminal GND.
When F/R and terminal GND are not switched on, the motor runs clockwise (facing the motor shaft), and vice versa,
the motor runs
counterclockwise.
To avoid damage to the drive, when changing the motor steering, the motor should
be stopped before operating to change the steering. Changing the direction of operation while the motor is running
should be avoided.
4.5 Braking Stop (BK)
The braking stop of the motor can be controlled by the connection of control terminal BK to terminal GND. When
control terminal BK is disconnected from terminal GND, the motor runs, when it is switched on the motor quickly
brakes to a stop, braking stop is faster than natural stop, the specific stopping time is related to the load inertia of the
user's system.
Attention: As the brake stop has a bad impact on both the electrical and the mechanical, a natural stop should be
used if there are no special stopping requirements.
4.6 Motor Speed Signal Output (PG)
The speed pulse output is a 5V pulse output, to obtain the signal a pull-up resistor of 3K ohm ~10K ohm should be
connected to the power supply. The number of output pulses per revolution of the motor is 3 x N, N being the
number of pairs of poles of the motor. For example: 2 pairs of poles, i.e. a four-pole motor, 6 pulses per revolution.
When the motor speed is 500 rpm, the output pulse of the terminal PG is 3000.
4.7 Alarm Output (ALM)
Alarm output of the driver: this terminal is low during an alarm. To obtain a signal, a pull-up resistor of 3K ohm to
10K ohm should be connected to the power supply. When the alarm is on, this terminal is connected to GND (low
level) and the driver stops itself and is in alarm.
4.8 Driver Failure
If a fault occurs inside the driver such as overvoltage or overcurrent, the driver enters a protection state, the driver
will
automatically
stop working, the motor stops and the red light on the driver is always on. The driver can only
disarm the alarm if the enable terminal is reset (i.e. EN is disconnected from GND) or if power is cut off. Please check
the motor wiring or remove the load if this fault occurs.
