FG | Motor speed pulse output is measuring the frequency of this signal. Then converts it into the actual motor speed. | |
DIR | Rotary direction is controlled by high and low electrical level, motor forward: connected with GND1, motor reversal （anticlockwise） ;without GND1 or connected with +5V, motor forward (clockwise) | |
EN | Connected EN with GND1, motor can work(online status);without connected or high electrical lever, motor can not work(offline status and the red light keep working) | |
GND1 | Control signal’s power supply | |
Hall control port | +5V2 | + motor’s Hall power |
HU | Hall sensor signal U phase input | |
HV | Hall sensor signal V phase input | |
HW | Hall sensor signal W phase input | |
GND2 | The motor’s Hall power supply | |
The motor and power | U、V、W | The motor’s three-phase output signal |
GND、V+ | GND、V+ stand for direct current flow. The input power is DC18V～50V.(boards show DC24V-48V) |
Function and method:
Speed mode (VSP/PWM) | 1. The external input speed: two external terminals of the external potentiometer(5K-10K) respectively connected to the driver's GND1 and +5 V1 terminal. If the regulator is connected to the VSP end, you can use an external potentiometer to adjust speed. It can also be made by the other control unit’s (such as PLC, microcontroller, etc.) input analog voltage to VSP side (relative to GND1). VSP port accepts the range of DC 0V ~ +5 V and the corresponding motor speed is 0 ~ rated speed; 2. PWM speed: the PWM’s positive end is connected to the VSP. The negative end connects with GND1. The frequency is 10Hz-300KHz, changing the duty cycle speed. |
Speed signal output （FG）
| The drive provides the motor speed pulse signal, which is positive proportion to the motor speed, pulse output way: RPUP 4.7k, open collector output 1. the motor speed (RPM) = F ÷ N× 60 F = actually measured frequency current on the FG foot by frequency table N = Pole logarithm , 2 pole motor, N = 2; 4 pole motor, N = 4 For example: the user selects a 4 pole motor. When the output FG signal is 200Hz, the motor speed = 200 ÷4× 60 = 3000 r / min. |
The motor positive and negative signal（DIR） | By controlling high low-level of DIR to control the motor’s positive and reverse turn. Noticed: Swerved suddenly when motor is at high speed, to avoid the damage of motor and equipment , when DIR get the transform single , we must make motor stop running for 2s, then change the motor direction ,improve speed to the set value.
|
Start/Stop signal（EN）
| By controlling high low-level of EN to control the motor’s stop and run. When EN is low level, motor run; when EN is high level or non-connect ,motor stop working, red light keep working. Power consumption is less than or equal to20MA. Fault Value : short circuit with EN and GND. |
Safety attention：
1、The motor and drive wiring must be connected in the power-off state. Do not connect electrical wiring under power.
2、According to the illustrated method, connect the power cord, motor winding wire and Hall signal line correctly. Please pay attention to the order of UVW three-phase must be consistent.
3、Do not disassemble the drive at random to prevent damage.
4、Do not touch all terminals on power-on state.
5、Do not drive without shell operation
6、Impact of the drive may cause damage.

FAQS：
1. How can get it started as soon as possible when you first use the drive?
After you correctly connect the power cord, the motor line, the Hall line, the external potentiometer slowly accelerates. After the motor is turned correctly, you can test the enable, direction and other functions. If you are unfamiliar with the product, the initial use should be done after the test. And then it can be installed to the actual use.
2. What will come about if power supply is reverse?
It will immediately burn the drive.
3. What is the maximum of the upper control signal voltage ?
The maximum voltage of the speed regulation signal is 5V. Exceeding this voltage will cause the drive to burn.
4. After the driver has been working for a long time, the shell is hot. Is it normal?
Yes, it is. At room temperature, after long working hours, it is up to 90 degrees. And it will not affect the performance.
5. The power indicator is light, but the motor does not turn and shift, what is the reason?
There may be a mistake in the phase line and the Hall line. Please re-energize the wiring according to the motor manual.
6. Can my motor speed transferred to 6000 with this drive?
The maximum speed of the brushless motor is determined by the parameters of the motor itself. The drive can control the motor speed from 0 to the highest speed.
7. I already have a motor and how to install this drive after wiring?
You must first determine the motor phase and the definition of the Hall line, and then you can connect it with wires. If you are not sure, you need to ask the motor manufacturers. Incorrect wiring can cause damage to the drive.
8. Can I add some features on this drive or do new product development?
Yes, please contact us.
