2.3 Driver installation requirements
Please install the driver vertically or horizontally, with its front facing forward, top facing upward to
facilitate cooling.
During assembly, avoid drillings and other foreign matters falling inside the driver.
During assembly, please use M3 screw to fix.
When there is vibration source (such as a driller) close to the installation position, please use a vibrating
absorber or a vibration resistant rubber gasket.
When multiple drivers are installed in the control cabinet, please pay attention to reserve enough space
for sufficient heat dissipation. If necessary, you can configure cooling fans to ensure good heat
dissipation conditions in the control cabinet.

3.2 Power supply input
The driver's working power is DC power, and the input voltage range is between 24V ~ 48V.
Input power polarity should not be reversed!!!
The driver’s work mode is constant current control. The driver output the voltage to motor by changing
the input power into PWM chopping wave when it is working. In this case, the input power will affect the
performance of driver.
Power selection reference:

Voltage:
Stepper motor has the characteristics of torque decrease with the increase of motor speed, and the input
voltage will affect the amplitude of high-speed torque reduction. Properly increasing the voltage of the
input power supply can increase the output torque of the motor at high speed.
Therefore, if you want to get better high-speed performance, pls increase the power supply voltage of
the driver; and for low-speed applications, choosing a slightly smaller voltage can appropriately reduce
the heat of the motor.
Current:
The working process of the driver is to convert the input high-voltage and low-current power supply into
the low-voltage and high-current at both ends of the motor winding. In actual use, the appropriate power
supply should be selected according to the motor model, load torque and other factors.
The effects of regeneration voltage:
When the stepper motor is working, it also retains the characteristics of the generator. When
decelerating, the kinetic energy accumulated by the load will be converted into electrical energy and
superimposed on the driver circuit and input power supply.
Pay attention to the setting of acceleration and deceleration time to protect the driver or power supply.
When the driver is powered off, you will see the driver's LED indicator on when the load is pulled to make
the motor move, which is also affected by this.

There is only one connection mode for 4 leads motor.
Series and parallel connection mode are used by 8 leads motor:
When series used, the winding inductance increased. The set of driver current should be about 0.7times
than before. This is suitable for low speed required.
When parallel used, the winding inductance decreased. The set of driver current should be about
1.4times than before. This is suitable for high speed required.
Parallel and central tapping connection mode are used by 6 leads motor:
When parallel used, all the winding connected, and the inductance was higher. This is suitable for low
speed required.
When central tapping used, half of the winding connected, and the inductance was lower. This is suitable
for high speed required.
3.4 Control signal connection
3.4.1 PUL, DIR port: connection for pulse command
The standard R series driver signal interface is in the form of pulse, and R60 can receive two kinds of
pulse command signals.
The upper controller can be the pulse signal generating device, such as PLC, MCU, control card and
controller.
The pulse level that R60 driver can be used: 3.3V-24V (no need to connect resistor)
Pulse and direction (PUL +
DIR)
Double pulse (CW +CCW)
3.4.2 ENA port: used to enable or disable
When the internal optocoupler is off, the driver outputs current to the motor;
When the internal optocoupler is on, the driver will cut off the current of each phase of the motor to make
the motor free, and the step pulse will not be responded.
When the motor is in error state, ENA input can be used to restart the driver. Firstly, the fault is eliminated,
and then a falling edge signal is input to the ENA terminal. The driver can restart the power part and the
motor is excited.
The level logic of the ENA signal can be set to the opposite, with the logic being opposite to the above.

DIP SW1, SW2, SW3 are used to set current which is output from driver to motor.
Generally, the current setting is the motor rated current. If your system has high request to the heating,
please decrease the current properly to lower the motor’s heating, but at the same time, the output
torque will be lower. If you don’t need the motor running continuous, you can increase the current to
higher the torque. But be minded that the current can not be 1.5times over than the rated current.

DIP SW5, SW6, SW7, and SW8 are used to set the pulse per revolution required by the motor.
Motor speed = command pulse frequency / pulse per revolution
Motor stroke = number of command pulses / pulse per revolution
4.3 Half / full flow selection
DIP SW4 is used to set the static current value when the motor is stopped
Off means that when the driver's power-on pulse stops, the driver switches the current output to the
motor to half (half current) when it is rotating;
On means that when the driver's power-on pulse stops, the driver maintains the same current output to
the motor as the rotation (full current) ). In general use, SW4 should be set to off, so that the heat of the
motor and driver is reduced, and the reliability is improved.
