|Support Maximum Speed
||Speed above 20000 rpm, the specific speed depends on the motor itself and the load
||1. Control panel potentiometer: use this potentiometer to adjust the speed
2. External potentiometer: connect the potentiometer to the terminal block behind the controller for speed regulation
3. External 5V speed regulation voltage: Connect 5V speed regulation voltage from the terminal block on the back of the controller
||PG signal: There is a 5V speed pulse output between this port and the ground. The output frequency is set to P (Hz), the number of motor stages is N, and the speed is F (RPM), then the output speed frequency: P=F*N/60
||ALM signal: There is an alarm pulse output between this port and the ground
1. In normal operation, this port outputs 5V high level
2. When it is turned on, but the speed control signal is very low and the motor does not rotate, the port signal is low, that is: when the EN enable key is turned on, as long as the motor does not rotate, the alarm port signal is always low , Prompting that the current status is abnormal or there is a question, to be dealt with
3. In the case of undervoltage, overvoltage, locked rotor, phase loss, phase short circuit, etc., the port signal is low level
|Forward and Reverse Function
||F/R: An external switch is connected to the corresponding position of the rear terminal block, one end of the switch is connected to the F/R port, one end is grounded, the switch is turned on and off, and the rotation direction of the motor can be changed
||1. Toggle switch on the panel
2. Connect the switch to the corresponding position of the rear terminal block to control the start and stop
Note: The two methods cannot be used at the same time. When using one method, the switch of the other method should be in the on position
|Locked Rotor Protection
||When the motor is locked, the motor stops working and restarts when the power is turned on
||Green light: always on when power is on
When the boot is enabled, the potentiometer or the external voltage is not turned on, and it is in the semi-standby state, it flashes once at an interval;
Enable is not turned on, in standby state, flashes seven times at intervals
||Under normal temperature and pressure>100MΩ
||0.5KV at normal temperature and pressure, 1 minute
||Avoid direct contact with dust, oil fume and corrosive gases
||<80%, no frost, no frost

Vibration Motor Controller Wiring Diagram
Tips: Vibration motor controller functions and instructions
1. Speed regulation method (SV)
External potentiometer speed adjustment: connect the two fixed ends of the potentiometer to the controller "control
Connect the “+5V” and “GND” of the “control” terminal to “SV”. The recommended potentiometer resistance is 10K-100K.
External power supply speed adjustment: connect the negative pole of the external power supply to "GND" and the positive pole to "SV", the voltage is 5V
2. Motor forward/reverse control (F/R)
The direction of the motor is controlled by switching the forward and reverse switches.
3. Enable switch (EN)
The brake and stop of the motor can be controlled by the on and off of the control terminals "EN" and "GND".
4. Alarm failure (ALM)
In the following situations, the ALM output will change from a 5V high level signal to a low level, prompting to check
When the enable switch is turned on, the speed regulation is not started, and the motor does not rotate; when the voltage supply due to under-overvoltage is abnormal
When there is a stall, motor phase line short circuit, phase line lack of phase, etc.
5. Motor speed signal output (PG)
The controller provides customers with a pulse signal proportional to the motor speed through the terminal "PG", the pulse amplitude is 5V.
Rotation speed = pulse frequency ÷ number of poles of the motor × 60 (seconds)
Example: A 4-pole motor, the pulse signal is 50Hz, then its speed is: 50 ÷ 4×60 = 750 (RPM).
