2.3 Drive installation requirements
Please install the drive 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 drive.
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 drives 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 power supply of the drive can be both AC power and DC power, and the input voltage range is
24V~48VDC.
Input power polarity should not be reversed!!!
The drive’s work mode is constant current control. The drive 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 drive.
Power selection reference:
Voltage:
The stepper motor has the characteristic of torque decreasing as the motor speed increases, and the
voltage of the input power supply will affect the declining amplitude of the motor torque at high speed.
Increasing the voltage of the input power supply appropriately can increase the output torque of the
motor at high speed. And use low voltage when it is low speed required, can lower motor’s heating
appropriately.
Current:
The work of the drive is to convert the input power supply with high voltage and low current to the low
voltage and high current at both terminals of the motor winding.In this case, the current of power supply
will be lower than the motor’s.
The effects of regeneration voltage:

When the stepper motor is working, it also keeps the characteristics of the generator. At deceleration, the
kinetic energy accumulated by the load is converted into electric energy, which will be superimposed on
the drive circuit and the input power. In application, attention should be paid to the setting of acceleration
and deceleration time to prevent the protection of the drive or power supply.
When the drive is powered off, similarly, the drive LED indicator will be on if the load is increased to allow
the motor to move

The matching motor of the R60-IO drive is the low resistance and low inductance hybrid stepper motor.
The common 2-phase stepper motor’s lead number are 4, 8 and 6.
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 drive 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 drive 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.

When IN1 is turned on and IN2 is turned off, the motor is triggered to rotate
forward; when IN1 is turned off, the motor decelerates to stop.
When IN1 is turned on and IN2 is turned on, the motor is reversed. When IN1 is
turned off, the motor decelerates to a stop.
When IN1 is off, the motor stops running. (default is this mode)
S p e e d m o d 2

When IN1 is turned on, the motor is triggered to continue to rotate forward;
when it turns from on to off, the motor decelerates and stops.
When IN2 is turned on, the motor is triggered to continuously reverse; when it
turns from on to off, the motor decelerates and stops.
When IN1 and IN2 are both on, the motor will stop running.
Note: The IO driver defaults to mode 1. If you need to adjust, please explain to Rtelligent.
3.4.2 ENA port: used to enable or disable.
By default, the driver outputs current to the motor when the photocoupler is turned off. When the

internal photocoupler is turned on, the driver will cut off the current of each phase of the motor to
make the motor in a free state. At this time, the step pulse is not responded.
When the motor is in an error state, the ENA input can be used to restart the drive. First remove
the fault, then input a falling edge signal to the ENA terminal, the driver can restart the power part,
and the motor excites.
The level logic of the ENA signal can be set to the opposite, and the logic is opposite to the
above.

DIP SW1, SW2, SW3 are used to set current which is output from drive 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, SW8 are used to set the speed when the motor is triggered. Built-in S-type
acceleration and deceleration.
When the switch is closed, the motor accelerates to the set speed.
When the switch is off, the motor decelerates and stops.
4.3 Acceleration selection
DIP SW4 is used to set the acceleration of the motor when it is running.
“Off” means the acceleration gear position “1” and the acceleration is moderate;
“On” means the acceleration gear position “2”, and the acceleration is large.
※The default acceleration for the general application is gear 1.
