🔌 Wiring & Internal Functions

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/reverse rotation control. High: 5V, Low: 0V. Controlled by touch switch 2 (F/R), default is high level.

⑥

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

⑦

Analog voltage output (0~5V). Suitable for motors accepting analog voltage speed regulation.

⑧

PWM1 reverse output. Suitable for motors accepting PWM speed regulation (speed is inversely proportional to duty cycle).

⑨

PWM2 forward output. Suitable for motors accepting PWM speed regulation (speed is proportional to duty cycle).

⑤-⑨

The output signal changes of the three interfaces are adjusted by the potentiometer.

⑩

Motor feedback signal input.

Feedback Configuration (FG/FG*3): Jumper cap placement depends on actual motor feedback times. No jumper cap is single times FG; adding the jumper cap enables 3 times FG*3. The same rule applies to CW/CCW direction configurations.

⚙️ Governor Parameter Settings

Frequency Setting

Press and hold touch switch 1 before powering on. Connect power to the board and release the switch when the screen displays "FEQ:20K". Touch switch 1 to decrease, and touch switch 2 to increase the frequency. Adjustable to specified frequency (factory default: 20KHz).

Poles Number Setting

Press and hold touch switch 1 and 2 simultaneously before powering on. Connect power and release switches when the screen shows "number of poles: 1 polarity". Touch switch 1 to decrease, and touch switch 2 to increase. Configure to match your motor design (factory default: 1 pole).

Feedback Setting

Refer to FG/FG*3 pin setup. Set according to whether the feedback multiplier of the motor is single FG or three times FG. Add jumper cap for 3 times FG; remove jumper cap for single FG.

Direction Setting

Refer to CW/CCW pin setup for initial state direction. Configure depending on whether the motor runs CW or CCW when the direction line is suspended. CCW requires the skip cap added; CW requires no skip cap.

Main Interface Screen: The display mainly monitors input voltage, speed, frequency, and duty cycle. For correct speed display, FG/FG*3 feedback and motor pole settings must be set properly.

⚠️ Important Precautions

🚨
Connection Polarity: Power input terminals must be wired correctly. Never reverse positive and negative connections; doing so will damage or burn out the governor.
🔧
Interface Compatibility: Ensure your motor matches the specified control interface options described above.
⚡
Voltage Limitation: Do not apply a voltage higher than 5V to the control ports (⑤ through ⑨).

💬 Frequently Asked Questions (FAQ)

Q1: What should I do if my motor requires more than 2A of current?

A1: The governor is rated for a maximum of 2A. To control a motor demanding higher current, connect the motor's power lines directly to the main power supply rather than through the governor interface.

Q2: How do I change the default frequency setting?

A2: Hold touch switch 1 down prior to power-on, turn the power on, release it when the screen displays "FEQ:20K", and adjust using switch 1 (to reduce) or switch 2 (to increase).

Q3: How do I set the correct motor pole configuration?

A3: Hold both touch switches 1 and 2 before powering on. Connect power, release the switches when "number of poles: 1 polarity" displays, and adjust the poles value using switch 1 and 2 to match your motor's hardware configuration.

Q4: What happens if I reverse the input power supply polarities?

A4: Reversing the positive and negative connections will cause the governor to fail immediately and will burn out the inner electronic circuitry. Always double-check wire alignments.

Q5: Can I input more than 5V signals to the control ports?

A5: No, the five signal ports (⑤-⑨) must never exceed a 5V input threshold to avoid damaging the internal microcontroller logic gates.
