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.
Note: The output signal changes of the three interfaces (⑤ to ⑨) are adjusted by the potentiometer.
⑩Motor feedback signal input.
Note: 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.
3. 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 and switch 2 to add. The factory default is 20KHz.
(2) Pole Number Setting
Before power-on, hold down both touch switch 1 and touch switch 2 and do not release. Power the governor board and wait until the screen shows "number of poles: 1 polarity" before releasing the buttons. Touch switch 1 to reduce and switch 2 to add. The factory default is 1 pole.
(3) Feedback Setting
The FG/FG*3 pin is set as the feedback multiple. It is 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 is the direction setting of the motor in its initial state. It is set based on whether the motor is CW or CCW when the motor direction control line is suspended. CCW is configured with the skip cap added, and CW is configured without the skip cap.
Main Screen Display: The current screen displays the input voltage, speed, frequency, and duty cycle. The speed must be set to normal display FG/FG*3 and pole number.
4. Governor Precautions
Important Operational Safety
(1)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 will not work and will burn out.
(2)The governor is used to match the motor with the specified control interface.
(3)The five ports (⑤ to ⑨) cannot access a voltage exceeding 5V.
Frequently Asked Questions (FAQ)
Q1: What is the operating voltage range and maximum rated current of the governor?
A1: The governor operates within a voltage range of DC5V-28V and supports a rated current up to MAX 2A. To control a motor requiring greater current, connect the motor power line directly to the power supply instead of routing it through the governor.
Q2: How do I change the default frequency setting on the governor?
A2: Before powering on, press and hold touch switch 1. Turn on the power and release the switch when the screen displays "FEQ:20K". You can then use touch switch 1 to decrease the frequency or touch switch 2 to increase it. The factory default is 20KHz.
Q3: How is the number of motor poles configured?
A3: Press and hold both touch switch 1 and 2 before powering on the board. Release them when the screen displays the pole setup interface. Adjust the pole count using switch 1 (to decrease) and switch 2 (to increase). The factory default setting is 1 pole.
Q4: How do I switch the feedback multiplier setting between single FG and 3x FG?
A4: The feedback setting is adjusted via the FG/FG*3 pin. If you do not add a jumper cap, it defaults to a single times FG. If you add the jumper cap, it configures to 3 times FG*3.
Q5: What are the consequences of reversing the positive and negative power connections?
A5: The positive and negative power supply must be connected exactly as instructed. Reversing the connections will prevent the governor from operating and will burn out the unit.
Q6: What is the maximum voltage input allowed for the control ports ⑤ to ⑨?
A6: The control interfaces (⑤ to ⑨) can only accept signals within a safe threshold and must not access any voltage exceeding 5V.
