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



2
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.

rising edge of pulse. PUL high voltage is 24V, low
voltage is 0~0.5V.
Direction
High voltage 24V and low voltage 0~0.5V correspond to
control signal
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.
Enable signal
To release the motor. When ENA+ connects to 24V, ENAconnects 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.
Error signal
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:


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.

Notes:
Generally, the motor high-speed performance depends on the driver power voltage
(the bigger the power voltage, the higher the high-speed torque, step loss is avoided
effectively), motor output torque depends on the setting current (the larger the setting
current, the higher the motor output torque).
However, if the power voltage is large, low-speed running vibration is serious; if the
setting current is large, the heating of driver and motor is serious.

7. Motor Selection
The DP-708 series driver matches with 4/6/8 wires 2-phase hybrid stepper motor.
Please select the suitable motor and driver.
The DP-5022 series driver matches with 3/6 wires 3-phase hybrid stepper motor.
Please select the suitable motor and driver.
Please pay attention to the torque and rated current when choosing a motor. The
torque depends on the motor dimension, the bigger the dimension, and the greater the
torque. And the current depends on the resistor, the smaller the resistor, the greater the
current, and the motor will have good performance at high speed.
But for certain connection motor, the bigger the working current, the greater the
torque, the motor heating is serious; the higher the driver power voltage, the bigger
the motor high-speed torque. The high-speed torque of motor is smaller than
low-speed torque.
