2. Operation Guide
Please read the following suggestions carefully before you install the driver.
2-1. Safety
 The driver is authorized to be installed and operated by the professional staff.
 Don’t turn on the power before connecting to the motor.
 Make sure that the input signals meet the technical requirements.
 Don’t make the setting or measure operations on the motor and driver during
power on.
 Please do the wiring, installation and parameter setting after power is off for more
than 3 minutes.
 Ensure the connection operation is absolutely correct and fixable before you turn
on the power, including the power wire, motor cable and signal cable.
 Avoid electromagnetic interference.
2-2. Attention
 Please use shield cable for signal input, and leave each other for distance. The
further the distance, the better the interference is avoided.
 Please connect the motor cover to the GND terminal.
 Don’t operate on the output terminal when power on, or else the driver will be
damaged.
2-3. Installation
 Don’t install the driver next to the heating devices.
 Don’t exposure the driver to the dusty, corrosive gas, high humidity, and strong
vibration environment.
 For perfect conducting, the ground cable of PC, driver and motor should contact
with the ground for large area.

signal
The rising edge is effective; motor moves one step at the
rising edge of pulse. PUL high voltage is 24V, low
voltage is 0~0.5V.
PUL-
DIR+ Direction
control signal
High voltage 24V and low voltage 0~0.5V correspond to
two directions of the motor. Exchanging the signal can
change the motor direction. The original direction of the
motor depends on the wiring. Exchange any phase wiring
can change the motor turning direction.
DIR-
ENA+ Enable signal To release the motor. When ENA+ connects to 24V, ENA-
connects to low voltage, the driver will cut all phase
current of the motor, and the stepper pulse will not be
responded. Please let the terminal be vacant if out of use.

Output the error signal when the driver is under-voltage

3-1-2. Sequential chart of control signals
In order to ensure the reliability of the system response, please take the following
advices.
 The signal high voltage is 24V; low voltage is less than 0.5V.
 The ENA (enable) signal should turn to high-level at least 3s before DIR
(direction) signal.
 Ensure the falling edge of the DIR (direction) signal is built at least 5μs before
PUL (pulse) signal.
 The width of pulse should be more than 1.2μs
 The duration of the pulse low-voltage should be more than 1.2μs
The sequential chart is shown as below:
3-1-3. Input circuit
The common positive connection of input circuit is shown as below:
Note:
 All the input signals go through the photoelectric isolation. To ensure the well
conducting of inside high-speed optical coupler, keep the control signal current

 Optical coupler current limiting resistor is built in stepper driver. It is common to
supply all the control signals with +24V.

3-2-2. Requirement of power supply
 To keep the normal working of drive, please ensure the power supply in this
range: DP-708: 20~80VDC; DP-5022: 200~240VAC.
 For DP-708, it is advised to use non-regulated DC power supply, and make sure
the current output of power is 60% higher than setting current of driver.
 For DP-708, if use regulated DC power supply, the current of power supply is
higher than motor working current.

Note:
The motor performance depends on the connection between driver and motor.
Generally, the high-speed performance of motor depends on the power supply voltage
(the higher the power voltage, the higher the high-speed torque, can avoid the step
missing), and the output torque depends on the setting current (the greater the setting
current, the higher the output torque of motor).
However, please pay attention that the motor is getting hot when the power
voltage is higher, and the vibration is obviously big when the motor is running at a
low speed.
Above all, please do the connection according to the actual requirements.
There are some typical connections for your reference:
 8-wire parallel connection mode: the setting current is 1.4 times of rated motor
current.
 8-wire serial connection mode: the setting current value is 70% of rated motor
current.
 4/6-wire high-speed mode: the setting current value should be lower than the
motor rated current.
 6-wire high-torque mode: the setting current value should be 70% of the motor
rated current.
