Controller Parameters
| Items | Specifications |
|---|---|
| Rated Voltage | 20-50V DC |
| Rated Current | 10A |
Remark: Due to the large fluctuation of the vibration motor current, when the
working current is 10A on average, the actual maximum current will exceed 10A.
For the vibration motor, the average current should not be large, and 8A is
suitable.
Current limit| Approx. 12A
Remark: Current limiting is to avoid burning the motor and controller with
large load.
Do not use it over-rated current.
Maximum speed| Support speed above 20000RPM; the specific speed depends on the
motor and the load
Speed regulation| Three speed control methods:
1. Control panel potentiometer: speed regulation through this potentiometer
2. External potentiometer: adjust the speed by the potentiometer connected
with the terminal seat on the back of the controller
3. External 5V speed regulation voltage: 5V speed regulation voltage
connected with the terminal seat on the back of the controller
Remarks: Control panel potentiometer speed control and terminal block external
potentiometer or 5V voltage speed regulation cannot be used at the same time.
When using control panel for speed regulation, the external potentiometer or
5V speed regulation voltage is set low; otherwise, it is similar.
Speed output| PG signal: There is a 5V speed pulse output between the port and
ground.
The output frequency is set to P (Hz), the pair number of motor poles is N,and
the speed is F (RPM), and then the output speed frequency is:P=F*N/60.
Alarm output| ALM signal: an alarm pulse output between the port and ground.
1. In normal operation, the port outputs 5V high level
2. When the controller is turned on, but the speed control signal is very low
and the motor does not rotate, the port signal is in low level, that is, when
the EN enable button is turned on, the alarm port signal is in low level as
long as the motor does not rotate. It reminders that the current status is
abnormal, need to be processed.
3. In the case of under voltage, over voltage, and stall, phase loss, phase
shortcircuit, etc., the port signal is in low level.
Forward and reverse function| F/R：Connect a switch to the corresponding
position of the rear terminal block.
Connect one end of the switch to the F/R port, one end is grounded. The switch
is on and off, to control the direction of rotation of the motor.
Start & stop| Two ways to start and stop
1. A toggle switch on the panel
2. Connect a switch to the corresponding position of the rear terminal block
for start and stop control.
Note: The two methods cannot be used at the same time. When using one method,
the switch of the other way is to be in the open position.
Stall protection| When the motor is blocked and stops working, re-power and
start up.
Power light| Green light: Lights up when power is on
Status light| Red light: Enable the power on, the potentiometer or the
external voltage is not turned on, in the semi-standby state, the red light
flashes one time at the interval.
Enable power is not on, in standby state, the red light flashes seven times
with the interval.
Insulation resistance| >100MΩ (Under normal temperature and pressure)
Dielectric strength| 0.5KV, 1 min (Under normal temperature and pressure)

Terminals Wiring Method
The terminal block from top to bottom is defined as:
Wiring tips:
Find the 5-digit terminal, from left to right, it is the positive (+) of the
DC power supply, Input power negative (-), motor wire blue, brown, white.
Terminals Definition
| Items | Mark | Definition & Function |
|---|---|---|
| Control Signal | F/R | Forward and reverse switching interface, and the other |
end is connected to GND
SV| 1. Speed regulation potentiometer intermediate terminal wiring position,
to adjust the speed
2. External SV positive terminal connection position, to adjust the speed
ALM| Alarm signal interface, the other end is connected to GND
PG| Speed signal interface, the other end is connected to GND
EN| Switch on/off interface, the other end is connected to GND
+5V| Control signal power 5V
GND| Ground wire
Motor terminals| U, V. W| Correspondingly connected to the motor line.
Note: Wrong connection will cause the motor to work abnormally, even
damage the controller and the motor.
DC Input| V+| DC input terminal
GND| Ground wire
Indicator Light| RUNM| Green power light: Power on, and the light is on.
Indicator Light| ALM| Red status light: in standby and semi-standby status,
the LED light flashes 1 time and 7 times; in the case of stalling, phase loss
or phaseline short circuit and other faults, LED is always on and other
flashingtimes.
Function & Instruction
-
Speed control mode (SV)
1. External potentiometer speed adjustment: connect the two fixed ends of the potentiometer to “+5V” and “GND” of the “control” terminal of the controller respectively, and connect the adjustment terminal to “SV”. It is recommended that the potentiometer value be at 10K–100K.
External power supply speed regulation: connect the negative pole of the external power supply to “GND” and the positive pole to “SV”, the voltage is 5V. -
Motor forward/reverse control (F/R)
Controls the direction of the motor by switching the forward and reverse switches. -
Enable switch on/off (EN)
Control the braking and stopping of the motor by controlling the opening and closing of the terminals “EN” and “GND”. -
Alarm for failure (ALM)
The following conditions will cause the ALM output to go from a 5V highlevel signal to a low level, giving a reminder for a check:
When the enable switch is turned on, the speed regulation is not started, and the motor does not rotate; when the under voltage or over voltage occurs, or the voltage supply is abnormal; when the stall occurs, the motor phase line is short-circuited, and the phase line is out of phase, etc. -
Motor speed signal output (PG)
The controller provides the customer with a pulse signal proportional to the motor speed through the terminal “PG”. The pulse amplitude is 5V.
Speed = Pulse frequency ÷ pair number of motor poles × 60 (seconds)
For example: A 4-pole motor with a pulse signal of 50Hz, then its speed is: 50÷ 4 × 60 = 750 (RPM).
Faults & Troubleshooting
| Faults | Causes |
|---|---|
| The motor does not rotate. | 1. Check if the power supply is normal. |
2. Check that the motor cable wiring is correct and firm.
3. Check if the potentiometer is wired correctly and rotated to the correct
position.
Motor speed is very slow.| 1. Check if the voltage is normal.
Alarm LED light is always on or flashing continuously.| In addition to the
flashing of standby and semi-standby: 1. Check if the working voltage is
normal.
Alarm and LED is always on.| 1. Check if it is at stall.
2. Check if it is lack of phase.
3. Check if the phase line is shorted.
Note:
After the motor is well connected, try the test running first. First make the
motor run at low speed, then gradually increase the speed, and then connect
the load after there is no problem.
In the running process, pay attention to whether the motor is very hot. In
tens of seconds to a minute or two, the temperature will rise to the situation
that people feel very hot, stop the motor in time and check the cause of the
problem.
The controller specification will be improved continuously. If there is
something that you don’t understand or is wrong, please contact us in time.
