illuminated for failure or offline
+5V1: Control signal power supply positive (built-in power output)
VSP: External speed control signal, through external potentiometer, etc. to achieve 0-100% motor speed
regulation

frequency of the signal.
DIR: High and low level control motor forward and reverse, connected to GND1 motor reverse, not
connected to GND1 or + 5V1 motor forward and reverse, in order to reduce the impact, it is better
to set EN high first, so that the motor stops working.

- HV: Hall sensor signal V phase input
- HW: W phase input of Hall sensor signal
- GND2: Electric Hall Power Source
- Motor and power supply end:
- U, V, W: Three-phase output signal of motor connected with motor winding
- V-, V+: DC power supply input from 18V to 50V. (panel nominal DC24V~48V)
Functional description:
Speed control mode selection (VSP/PWM):
1. External input speed regulation: Two fixed ends of external potentiometer (5K~10K) are connected to
GND1 and+5V1 ends of driver respectively, and the regulating end is connected to VSP end. The external
potentiometer speed regulation can be realized by using external potentiometer, or by inputting analog
voltage to VSP end through other control units (such as PLC, MCU, etc.). The receiving range of VSP
port is DC 0V~+5V, corresponding to motor switching. Speed is 0~rated speed.
2. PWM speed regulation: connect the positive end of PWM to VSP, and the negative end to GND1.
The input frequency is 10Hz-300Hz, and the duty cycle is changed.
Speed measurement signal output (FG):
The driver provides the motor speed measurement pulse signal, which is proportional to the motor speed.
The output mode of the pulse is the open circuit output of the pull-up resistance 10K collector.
Speed calculation method: motor speed (RPM) = F_N *60
F = Frequency on FG foot measured by frequency meter
N = motor pole logarithm (2 pole motor N = 2; 4 pole motor N = 4)
For example, when the user chooses two pairs of pole motors, when the output FG signal is 600Hz,
the speed of the motor is 600_2*60=1800 rpm.
Direction/Inversion Signal (DIR): By controlling the high and low level conversion of DIR terminal,
the forward and reverse of motor can be controlled.
Note: In order to avoid sudden commutation and huge impact on motor and mechanical equipment
during high speed operation, when the DIR terminal receives the commutation signal, the driver first
slows down the motor until it stops. After stopping about 2S, the motor changes its direction and
increases its speed to the set speed.
Motor Start/Stop Signal (EN): By controlling the high and low level conversion of EN terminal,
the stop and operation of the motor can be controlled. When EN is high level, the motor works
normally; when EN is low level or short connection, the motor stops working and is in free state,
and the red light is always on. At this time, the power consumption of the driver is less than 20 mA.
The factory is set to EN and GND disconnection.
