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), 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 default is 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 motors accepting PWM speed regulation, where speed is inversely proportional to the duty cycle.
9
PWM2 forward output. This interface is suitable for motors accepting PWM speed regulation, where speed is proportional to the duty cycle.
10
Motor feedback signal input.
Adjustment Note: The output signal changes of the three interfaces (7, 8, and 9) are adjusted by the potentiometer.
FG/FG*3 & CW/CCW Configuration: FG/FG*3 should be configured based on actual motor feedback times. Without a jumper cap, it defaults to a single times FG. With an added jumper cap, it operates at 3 times FG (FG*3). The same setting rule applies to CW/CCW direction configurations.
Governor Parameter Settings
(1) Frequency Setting
Press and hold touch switch 1 before powering on. Power the board and release the button once the screen displays "FEQ:20K". Touch switch 1 to decrease or touch switch 2 to increase the value. The adjustable frequency default is 20KHz.
(2) Number of Poles Setting
Before powering on, hold down both touch switch 1 and touch switch 2 simultaneously. Power the board and release the buttons when the screen shows "number of poles: 1 polarity". Touch switch 1 to decrease or touch switch 2 to increase. The factory default is 1 pole.
(3) Feedback Setting
The FG/FG*3 pin sets the feedback multiple based on the motor's feedback requirement. Adding the jumper cap sets it to 3 times FG, while removing the jumper cap defaults to a single time FG.
(4) Direction & Display Settings
Direction: The CW/CCW pin configures the initial state of the motor. CCW is active with a skip cap added; CW is active without the skip cap when the direction control line is suspended.
Main Screen Display: Displays input voltage, speed, frequency, and duty cycle. Speed requires correct configuration of FG/FG*3 and pole numbers for accurate display.
Important Safety Precautions
The positive and negative power supply of the governor must be connected in accordance with the instructions and must not be reversed. Reversing the polarity will prevent operation and burn the governor.
The governor must be matched with motors utilizing the specific control interfaces mentioned.
The five control ports (numbered 5 through 9) must not access a voltage exceeding 5V.
Frequently Asked Questions (FAQ)
Q: What is the maximum voltage and current this governor can handle?
A: The governor supports a voltage range of DC 5V-28V with a rated maximum current of 2A. For motors requiring more current, the motor power line must be connected directly to the power supply instead of passing through the governor.
Q: What happens if the positive and negative power inputs are connected backward?
A: The positive and negative power connections must not be reversed. Doing so will prevent the governor from functioning and will permanently burn the device.
Q: How do I adjust the output frequency on the governor?
A: 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 and touch switch 2 to increase the frequency. The factory default is set to 20KHz.
Q: How do I configure the number of poles for my motor?
A: Press and hold both touch switch 1 and touch switch 2 simultaneously before powering on. Power the board and release the buttons when the screen shows "number of poles: 1 polarity". Adjust the poles using touch switch 1 (to decrease) and touch switch 2 (to increase) to match your motor's design.
Q: Can I input a voltage higher than 5V into the control and signal ports?
A: No, the five signal ports (interfaces 5 through 9, including direction, brake, analog voltage, and PWM outputs) are rated for low-level signals and must not access any voltage exceeding 5V.
Q: How do the FG/FG*3 and CW/CCW jumper settings work?
A: These are configured using jumper caps. For FG (feedback), adding the jumper cap multiplies the feedback signal by 3, while removing it sets it to a single feedback rate. For CW/CCW direction control, adding a skip cap sets the initial state to CCW, while leaving it off sets it to CW.
