2. Operation Guide
Please read the following suggestion 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 signal meets 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 the output terminal when power on, otherwise the driver will be
damaged.
2-3. Installation
Don’t install the driver next to the heat source.
Don’t expose the driver to the dusty, corrosive gas, moist environment, and work
in low vibration place.
For perfect conducting, please ensure the fixation between earth wire of host
computer, driver, motor and ground.

Notes:
The power supply voltage of driver determines the motor high speed performance (the
larger the voltage, the higher the high-speed torque, can avoid loss of synchronism),
set current determines the motor output torque (the bigger the current, the higher the
output torque).

DP-7022P Users Manual

However, when the power supply voltage is large, the vibration is large at low-speed;
if set current is large, the driver and motor heat is very serious.
For actual applications, users can select suitable current to achieve well effect.
3-3. Mode setting
The driver set the subdivision and current by parameters through panel. For more
details, please refer to chapter 4-2.
3-3-1. Current setting
Parameter P0.00 can set any current level in the range of 0~7.0A. Parameter
P0.01can set the half current and full current state.
3-3-2. Subdivision setting
Parameter P0.02 can set the subdivision resolution. For more details, please refer
to chapter 4-2.

4. Panel Operation
This chapter mainly introduces the operation of digital manipulator and its
application. The digital manipulator can set parameters and run the motor. We suggset
users use the digital manipulator when reading this chapter.
4-1．Basic operation
This section mainly introduces some basic operation about how to set running

7. Motor Selection
DP-7022P is suitable for 3/6-wire 3-phase hybrid stepper motor. Generally
speaking, select the motor according to the torque and rated current. The torque
depends on the motor dimension. Big dimension motor has big torque. The current
depends on the resistor. Small resistor has large current and the motor will have good
performance at high speed.
For certain wiring motor, the bigger the working current, the larger the output
torque, the serious motor heating. The higher the drive power voltage, the bigger the
motor high-speed torque. The motor high-speed torque is smaller than low-speed
torque.
