Functional Description

Indicator light

POWER

If the green power indicator is lighten, it shows that power is normal.

ALM

If the red status indicator is slow flash, it means waiting; Quick flash means operation; It always lights meaning faults or off-line;

RS232 communication port

TTL

It can be connected with an external speed display board to display speed. It can also access the computer to set the drive parameters. Details are shown in debugging software instructions

Control signal port

+5V1

Control signal power+( inner power output )

VSP

External speed control signal Control way: (1)By connecting with a potentiometer to change VSP, then it can complete 0 ~ 100% speed adjustment. The range is 0-5V;

(2)speed control by PWM: positive terminals connect with VSP, and negative terminals connect with GND1, inputting frequency by VSP to change duty cycle, and speed changed, the range is 10-300Hz

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

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.

1, Q: The motor does not turn and no holding torque:

A: ① check whether the power line is connected to the wrong voltage is too low, need to increase the voltage or correct the power line

② check whether the motor wiring is correct, if not correct motor wiring. Check if the motor wiring is correct, if not, correct the motor wiring.

③ Whether the enable signal is valid, resulting in the motor does not work.

④ Is the subdividing parameter correct?

⑤ Is the current parameter correct?

2、Q：Motor does not rotate but has holding torque:

A: ① The phase sequence of motor wires is wrong, need to swap any two wires.

② Pulse signal input is wrong, need to check the pulse wiring.

3、Q: The motor torque is too small:

A: ① Phase current setting is too small, need to set the phase current corresponding to the motor.

② acceleration is too fast, reduce the acceleration value

③ motor blocking, need to rule out mechanical problems

④ drive and motor mismatch, need to replace the appropriate drive

4、Q：Motor steering error:

A: ① motor line phase sequence is wrong, need to swap any two wires

② motor line has a broken circuit, check and connect the right

5、Q：The alarm indicator light is on:
