※When the driver has no pulse input for 500 milliseconds, the current will automatically drop
to 50% of the set current, which is the factory default value to reduce motor heating. When
pulse input is effective, the current returns to the set value. When the customer requires the
driver to keep 10%~90% of the stop current when there is no pulse input (the motor
generates more heat), please contact our company.

4. Regenerative Discharge
When the motor decelerates, it will convert the kinetic energy of the load into electrical
energy like a generator. Part of the energy will be consumed by the drive and motor. If your
application has a large load running at high speed, considerable kinetic energy will be
converted into electrical energy. It is easy to cause over-voltage alarm of the drive, and may
even cause damage to the drive. Because this driver has a power supply reverse connection
protection, it can prevent damage to the driver caused by power supply reverse connection.
Due to the shortcomings brought by this function, the power supply current of this driver
only flows in and does not flow out, and the external absorption resistors or capacitors is
invalid.
※When your application has a large load running at high speed, please contact the company
in advance to remove the anti-reverse connection function and connect an external
absorption resistor or capacitor. When there is no anti-reverse connection function, please
pay attention to the positive and negative polars of the power not to be reversed. There is
no warranty service for the damage of the driver caused by the reverse connection of the
power.

11
5. Motor connection
When the motor is connected to the driver, please make sure that the power is turned
off. Make sure that the unused wires are not short-circuited with other objects. The motor
cannot be disconnected while the driver is energized. Do not connect the motor leads to the
ground or power supply.
Caution：
①Different motors use different colors of wires, so please refer to the motor data when
you use them. For example.
②The phases are relative, but the windings of different phases cannot be connected to the
terminals of the same phase of the driver (A+, A- are one phase, B+, B- are another
phase), if the rotation of the motor is not as expected, just exchange A+ and A-.
③The correct way to judge whether the stepping motor is in series or in parallel: rotate the
motor shaft by hand, without connecting the driver. If it can be rotated easily and evenly,
the wiring is correct. If the resistance is large, uneven, and there is a certain noise, it
means that the wiring is wrong.
6. Input Signal
6.1 Pulse：P+/P-
The driver port has a internal optocoupler, which can receive 5~24VDC single or
differential signals, and the maximum voltage can reach 26V. The change from off to on is
understood as receiving a valid pulse edge command. For NPN, low potential is valid (PNP
is high potential), and the driver will drive the motor for one step according to the
corresponding timing. For the normal operation of the driver, the duty cycle of the effective
potential signal should be below 50%. In order to ensure a reliable response to the pulse
signal, the duration of the pulse effective potential of the driver should not be less than 1 μ
s. The signal response frequency of the driver is 500kHz, and an excessively high input
frequency may get an incorrect response.
6.2 Direction：D+/D-
It can receive 5~24VDC single or differential signal, the highest voltage can reach 26V.
The turn-on and turn-off of the internal optocoupler are interpreted as the two directions of
motor rotation. The direction signal will change the direction of motor operation. This
terminal floating is equivalent to the input of the high potential signal. It should be noted
that it is necessary to ensure that the direction signal input of the driver is at least 10 μs

12
ahead of the pulse signal input, so as to avoid the wrong response of the driver to the pulse
signal. When the motor switches the direction of rotation, it must be switched after the
motor stops. The switching direction signal must be changed between the last pulse of the
current direction signal ends and the first pulse of the next direction. When there is no need
to switch the direction, the “Direction” signal can be left floating.
6.3 Motor Free：FR+/FR-
It can receive 5~24VDC single or differential signal, the highest voltage can reach 26V. When
the internal optocoupler is turned on, the motor phase current is cut off and the rotor is in a
free state (de-excitation). When this function is not needed, the “Motor Free”signal can
be left floating.

13
6.4 Typical Signal Connection
※The P, D and FR terminals have current limiting functions, which can be directly connected
to the input signal without the external series resistor step-down current-limiting protection.
The Vcc value is 3.5~26V.

7. Output Signal
7.1 Digital output circuit (Relay connection)
7.2 Digital output circuit (Optocoupler connection)
The alarm output is photoelectrically isolated, with a maximum withstand voltage of
30VDC and a maximum saturation current of 50mA.
When the driver is working normally, the output terminal is short-circuited with the low
potential.
When the driver alarms, the output terminal is floating.
Caution: When the relay is connected, both terminals of the
relay must be connected to a diode. For example, 1N4001.

9. Wiring Requirements
1) In order to prevent the driver from being interfered, it is recommended that the control
signal use an anti-interference cable and the shield layer is grounded. Except for special
requirements, the shield line of the control signal line should be grounded at a single
side. The host controller side of the shield line should be grounded, and the driver side
should be floating. In the same machine, it must be grounded at the same point. If it is
not a real ground wire, there may be serious interference, and the shield layer do not be
connected in this situation.
2) Pulse and direction signal wires and motor wires are not allowed to be wrapped side by
side. It is better to separate them by at least 10cm, otherwise motor noise will easily
interfere with pulse and direction signals and cause inaccurate motor positioning and
system instability.
3) If a power supply is used for multiple drives, parallel connection is required for the drives.
A chain connection from one to the other is not allowed.
4) It is strictly prohibited to plug and unplug the driver's strong current terminals (motor
and power terminals) in the power-on state. When the charged motor is stopped, a large
current still flows through the coil. Plugging and unplugging the strong current
terminals will cause instantaneous huge induced electromotive force to damage the
driver.
5) It is strictly prohibited to connect the wire to the terminal after soldering, otherwise the
terminal may be damaged by overheating due to the increase of the contact resistance.
6) The wiring head should not be exposed outside the terminal to prevent accidental short
circuit and damage to the driver.
Driver Installation
Install on the narrow side, use M3/M4 screws to tighten through the holes on both sides.
The power device of the driver will generate heat. If it is continuously working under the
condition of high input voltage and high power, the effective heat dissipation area should
be enlarged or forced cooling.
➢Do not use it in a place without air circulation or where the surrounding temperature
exceeds 40°C.
➢Do not install the drive in a wet place or a place with metal shavings.
