Function Description

Speed regulation mode selection (VSP) 1. The VSP port can be connected to an external potentiometer for speed regulation: connect the two fixed ends of the external potentiometer (5K~10K) to the GND1 and +5V1 ends of the driver respectively, and connect the adjustment end to the VSP end , you can use an external potentiometer to adjust the speed, or you can input an analog voltage to the VSP terminal through other control units (such as PLC, microcontroller, etc.) to achieve speed regulation (relative to GND1), and the VSP port accepts a range of DC 0V~+5V , the corresponding motor speed is 0~ rated speed;

2. The VSP port can input PWM signal for speed regulation: connect the positive end of the PWM signal to the VSP port and the negative end to GND1, and change the PWM duty cycle by setting a PWM signal with a frequency of 100Hz~100KHz and an amplitude of +5V to achieve speed regulation.

Speed measurement signal output (FG)

The driver provides the motor speed measurement pulse signal, which is proportional to the motor speed.

Speed calculation method: Motor speed (RPM) = F÷N×60

F = The frequency on the FG pin is actually measured with a frequency meter

N = number of motor pole pairs (2-pole motor N=2; 4-pole motor N=4)

For example, if the user chooses a 4-pole motor, then: when the output FG signal is 200Hz, the motor speed = 200÷4×60=3000 rpm.

Motor forward/reverse

Signal

(DIR) The forward and reverse rotation of the motor can be controlled by switching the high and low levels of the control terminal DIR.

Note: In order to avoid sudden commutation when the motor is running at a high speed, which will cause a huge impact on the motor and mechanical equipment, when the DIR terminal receives the commutation signal, the driver first decelerates the motor until it stops, and then the motor changes direction and accelerates to the set speed.

Motor start/stop signal (EN)

By controlling the conversion of high and low levels of terminal EN, the stop and operation of the motor can be controlled. When EN is at a low level, the motor runs normally; when EN is at a high level or not connected, the motor stops working, in a free state, and the red light is always on. When the start/stop terminal is used to control the motor to stop, the motor stops naturally. The law of motion is related to the inertia of the load. At this time, the input current of the driver is less than or equal to 30mA.

The factory setting is shorted between EN and GND1.

brake

(X1) By controlling the switching of high and low levels of terminal X1, the stop and running of the motor can be controlled. When X1 is low level, the motor brakes to stop running, and the red light is off when braking; when X1 is high level or not connected, the motor is allowed to run.
