1. Product introduction
1-1. Model naming rule
Take DP3F-705 as an example:
DP3F - 70 5
① ② ③
①: DP3F series closed loop stepping driver
②: Driver output maximum peak current 7A
③: The maximum supply voltage of the driver is 50VDC
1-2. Performance
⚫The encoder is used as position feedback, which can compensate the position deviation in real time, and
solve the problem of losing step of traditional stepping motor
⚫The current can be adjusted in real time according to the load and speed, so that the operation is more
stable and the motor heating is lower
⚫Compared with the open-loop stepping, the high-speed performance of the motor is significantly
improved
⚫The pulse and direction input voltage supports 5V and 24V, which can be set by sliding switch
⚫4-bit DIP switch, 16 levels subdivision can be set to meet the needs of most customers
⚫The rotation direction of the motor can be changed by switch
⚫It has power on auto-tuning function, can be set by switch
⚫It supports single and double pulse mode, can be set by switch
⚫Support smoothing time, can be set by switch and convenient for debugging and improves the stability
of motor operation
⚫Two digital input signals: enable signal input and alarm clear signal input
⚫Three digital output signals: alarm signal output, in place /Z signal output, brake signal output
⚫It has over-current, over-voltage, rotation blocking detection, out of step compensation and other
protection functions
1-3. Application field
It is suitable for all kinds of small and medium-sized automation equipment and instruments, such as engraving
machine, stripping machine, marking machine, cutting machine, laser machine, plotter, medical equipment, CNC
machine tool, automatic assembly equipment, electronic processing equipment, etc.

1-5. Safety precautions
(1) The drive must be installed and operated by professional technicians!
(2) The input voltage of the driver must meet the technical requirements!
(3) It is strictly forbidden to plug the strong current terminal of the driver when the power is on. When the motor
stops, there is still a large current flowing through the coil. Plug the strong current terminal will produce a huge
instantaneous induced electromotive force, which will burn the driver!
(4) Before power on, please ensure the correctness and firmness of power cable, motor cable and signal cable
connection!
(5) Avoid electromagnetic interference!

2-1-2. Installation environment
The reliable working temperature of the driver is usually within 60℃and that of the motor is within 80℃. To
ensure that the driver works within the reliable working temperature range, the driver should be installed in the
electric cabinet with good ventilation and proper protection. If necessary, a fan should be installed near the driver
for forced heat dissipation.Avoid being used in dust, oil mist, corrosive gas, high humidity and strong vibration.
2-2. Wiring
2-2-1. Typical wiring diagram
2-2-2. Wiring notice
(1) The pulse and direction signal cables and motor cables are not allowed to be bound side by side, and it is better
to separate them at least 10cm, otherwise it is easy to interfere with the pulse direction signal, resulting in
inaccurate motor positioning, system instability and other problems.
(2) If a power supply supplies multiple drives, parallel connection should be adopted at the power supply, and
chain connection from one to another is not allowed.
(3) It is strictly forbidden to connect the wire head to the terminal after adding tin, otherwise the terminal may be
damaged due to overheating due to increased contact resistance.
(4) The wiring head should not be exposed outside the terminal to prevent accidental short circuit from damaging
the driver.

3. Driver interface
3-1. Status indicator and troubleshooting
The green LED is the power indicator. When the driver is powered on, the LED is always on; When the drive is
powered off, the LED goes out.
The red LED is the fault indicator. When there is a fault, the indicator will flash continuously, then stop for one
second, and then flash continuously. When the fault is cleared by the user, the red LED is always off.
The continuous flashing times of red LED represent different fault information, and the specific relationship is
shown in the table below. The alarm output terminal outputs high level.
Flashing times
Fault
Solution
1
Over current or short
circuit
Check the power cable for short circuit
2
Over voltage
Check whether the power supply voltage is too high
3
Under voltage
Check whether the power supply voltage is too low
4
Motor open circuit or
poor contact
Check whether the power cable is well installed or
broken
5
Position over limit
Check whether the encoder cable is broken, check
whether the motor is blocked, and increase the
acceleration time appropriately
Note: since the driver does not have the function of reverse connection protection of positive and negative poles of
power supply, please confirm that the wiring of positive and negative poles of power supply is correct again
before power on. The reverse connection of positive and negative poles will burn out the safety tube in the driver.
