2. Governor Wiring and Internal Function Description
1Governor, motor power supply positive input.
2Governor, motor power input negative.
3The positive output of the power supply of the motor.
4Negative output of the power supply of the motor.
5High 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.
6High 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.
7Analog voltage output (0~5V), this interface is suitable for accepting analog voltage speed regulation motor.
8PWM1 reverse output, this interface is suitable for the motor that accepts PWM speed regulation, and the speed is inversely proportional to the duty cycle.
9PWM2 forward output, this interface is suitable for motors that accept PWM speed regulation, the speed is proportional to the duty cycle.
10Motor feedback signal input.
Notes on output interfaces:
* The output signal changes of the three interfaces (7 to 9) are adjusted by the potentiometer.
* 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 settings.
3. Governor Parameter Settings
1 Frequency Setting
Press and hold the touch switch 1 before power-on and do not release. Power up the governor board and wait until the screen displays "FEQ:20K", then release the button. Touch switch 1 to decrease the value and touch switch 2 to increase. The frequency can be adjusted to the specified frequency (factory default is 20KHz).
2 Number of Poles Setting
Before power-on, hold down both light touch switch 1 and light touch switch 2 simultaneously, then power the governor board. Wait until the screen shows "number of poles: 1 polarity" before releasing the buttons. Light touch switch 1 decreases the number, and light touch switch 2 increases it. Set this to match the pole count of your motor design (factory default is 1 pole).
3 Feedback Setting
The FG/FG*3 pin is used to configure the feedback multiple. Set this according to whether the motor's feedback multiplier is single FG or triple FG. Adding a jumper cap sets it to 3 times FG, while removing the jumper cap configures it to single times FG.
4 Direction Setting
The CW/CCW pin configures the initial state direction of the motor. This is configured based on whether the motor runs CW or CCW when the motor direction control line is suspended. Add a skip cap for CCW; leave it without a skip cap for CW.
Main Display Information: The current screen displays the input voltage, speed, frequency, and duty cycle. For correct speed display, the FG/FG*3 multiplier and pole number must be configured properly.
4. Governor Precautions
Important Warnings & Guidelines
Power Input Polarities: The positive and negative power supply of the governor must be connected in accordance with the instructions. Do not reverse the connections, otherwise the governor will fail to work and may burn.
Motor Compatibility: The governor is designed to match motors that utilize the control interfaces specified in this guide.
Port Voltage Limit: Do not access voltages exceeding 5V on the five control ports (from port 5 to port 9).
Frequently Asked Questions (FAQ)
What is the input voltage range and rated current for this governor?
The governor operates on a voltage range of DC 5V to 28V. The rated current is MAX 2A. If you need to control a motor requiring a higher current, connect the motor's power line directly to the external power source instead of passing it through the governor board.
How do I set the PWM frequency on the governor?
Before powering on, press and hold touch switch 1. Turn on the power and wait until the screen displays "FEQ:20K" to release the switch. You can then use touch switch 1 to decrease and touch switch 2 to increase the frequency to your specified requirements. The default factory setting is 20KHz.
How can I configure the motor's pole number on the driver board?
To set the motor poles, hold down both touch switch 1 and touch switch 2 at the same time before powering on. Power on the board, wait for the screen to show "number of poles: 1 polarity" and release the buttons. Use switch 1 to decrease and switch 2 to increase. The default is set to 1 pole.
What happens if I reverse the positive and negative power connections?
Reversing the positive and negative power connections will damage the governor. It will fail to work and will likely burn the internal circuitry. Always verify the wiring polarities before applying power.
How do the FG/FG*3 and CW/CCW jumper pins work?
The FG/FG*3 pin sets the feedback multiple. Leaving it without a jumper cap indicates a single feedback (FG), while adding the jumper cap sets it to three times feedback (FG*3). For direction (CW/CCW), adding a skip cap sets the initial suspended state to CCW, whereas removing it sets it to CW.
Can I input a voltage higher than 5V into the signal ports?
No. The five control ports (numbered 5 through 9, including rotation, brake, and PWM outputs) are designed for signal levels up to 5V. Exceeding 5V on these ports can damage the control board interfaces.
