Governor Wiring & Internal Function Description

1

Governor, motor power supply positive input.
2

Governor, motor power input negative.
3

The positive output of the power supply of the motor.
4

Negative output of the power supply of the motor.
5

High and low level output of positive and negative rotation control, high level 5V, low level 0V, controlled by touch switch 2 (F/R), the default is high level.
6

High and low level output of brake control, high level 5V, low level 0V, controlled by touch switch 1 (BRA), power on the default high level.
7

Analog voltage output (0~5V), this interface is suitable for accepting analog voltage speed regulation motor.
8

PWM1 reverse output, this interface is suitable for the motor that accepts PWM speed regulation, and the speed is inversely proportional to the duty cycle.
9

PWM2 forward output, this interface is suitable for motors that accept PWM speed regulation, the speed is proportional to the duty cycle.
10

Motor feedback signal input.

Note on Wiring Adjustment: The output signal changes of the three interfaces (5-9) are adjusted by the potentiometer. For interface 10 (Motor feedback signal input): FG/FG*3 should be based on the actual motor feedback times whether to add a jumper cap. No jumper cap is a single times FG, increased jumper cap is 3 times FG*3. The same goes for CW/CCW.

Governor Parameter Settings

1

Frequency Setting: Press and hold the touch switch 1 before power-on and do not release, then power the governor board. Wait until the screen displays "FEQ:20K" before releasing the button. Touch switch 1 to reduce or touch switch 2 to add. The adjustable frequency goes to the specified frequency (factory default is 20KHz).
2

Number of Poles Set: Before power-on, hold down touch switch 1 and touch switch 2 at the same time and do not release, then power the governor board. Wait until the screen shows "number of poles: 1 polarity" before releasing the buttons. Touch switch 1 to reduce or touch switch 2 to add. The adjustable pole number is the pole number designed for the motor (factory default is 1 pole).
3

Feedback Setting: In Figure 1, the FG/FG*3 pin is set as the feedback multiple. Set according to whether the feedback multiplier of the motor is single times FG or three times FG. Adding the jumper cap is 3 times FG, and not adding the jumper cap is single times FG.
4

Direction Setting: The CW/CCW pin in Figure 1 is the direction setting of the motor in its initial state. It is set according to whether the motor is CW or CCW when the motor direction control line is suspended. CCW with skip cap added, CW without skip cap.

Main Screen Display: The current screen mainly displays the input voltage, speed, frequency, and duty cycle of these four parameters. The speed must be set to normal display FG/FG*3 and pole number.

Governor Precautions

⚠

The positive and negative power supply of the governor must be connected in accordance with the instructions, and must not be reversed. Otherwise, the governor cannot work and will burn the board.

⚠

The governor is used to match the motor with the specified control interface.

⚠

Ports 5 to 9 cannot access more than 5V voltage.

Frequently Asked Questions (FAQ)

What are the input voltage and rated current limits for this governor?

The input voltage range is DC 5V to 28V. The rated current is MAX 2A. If you need to control a motor with higher current requirements, the motor power line must be connected directly to the power supply instead of going through the governor.

How do I adjust the PWM frequency settings on the governor?

Before powering on the governor board, press and hold touch switch 1. Turn on the power and wait until the screen displays "FEQ:20K" before releasing the button. You can then use touch switch 1 to decrease the frequency or touch switch 2 to increase it. The factory default setting is 20KHz.

How do I configure the number of motor poles on the display?

With the power off, press and hold both touch switch 1 and touch switch 2 simultaneously. Power on the board and release the buttons once the screen shows "number of poles: 1 polarity". Press switch 1 to decrease or switch 2 to increase to match your motor's design (factory default is 1 pole).

What happens if the positive and negative power supplies are reversed?

Reversing the positive and negative power supply connections is highly dangerous. Doing so will prevent the governor from operating and will burn out the internal circuitry of the driver board. Always verify connection polarity before powering on.

How do I set the motor feedback settings (FG vs. FG*3)?

Feedback multiplier configurations are managed via the FG/FG*3 pin jumper cap. Leaving the jumper cap off configures the governor for single times FG feedback, while adding the jumper cap sets it to three times FG (FG*3).

What is the voltage limit for the control interfaces (ports 5 to 9)?

The control interface ports (5 through 9) are designed to handle signal levels. You must ensure that these ports do not access any voltage exceeding 5V.
