1. Product overview
Thank you for choosing Rtelligent T series digital stepper servo driver.
Stepper servo is a stepper motor scheme formed based on the common open loop stepper motor in
combination with position feedback and servo algorithm, which features high speed, high torque,
high precision, low vibration, low heating and no loss of step.
Based on TI's new 32-bit DSP processing chip platform, T series stepper servo driver uses the field
oriented control (FOC) and vector field-weakening control algorithm in the servo driver, which has
the performance of surpassing the ordinary stepper in all aspects.
The built-in PID parameter adjustment function makes the motor better meet the application of
different kinds of loads.
The built-in field-weakening control algorithm makes the motor to reduce the magnetic field
characteristics and keep the power at high speed.
The built-in current vector control function makes the motor have the current characteristic of
servo and low heating.
The built-in micro-stepping command algorithm makes the motor can run while maintaining a
stable and low vibration at various speeds.
The encoder feedback with the built-in 4000 pulse resolution makes the positioning precision
increase and never loses the step.
In conclusion, the servo control scheme combined with the characteristics of the stepper motor
enables the T series stepper servo driver to better exert the performance of the stepper motor,
which can replace the servo application of the same power. It is a new choice of optimal cost
performance for automation equipment.

2.2 Driver installation dimensions
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 power supply of the driver is DC power, and the input voltage range is between 24V~ 50V.
Don't mistakenly connect the mains 220VAC directly to both ends of AC! ! !
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.
Stepper servo has a higher speed and torque output than ordinary stepper. Therefore, if you want to
get better high-speed performance, you need to increase the power supply voltage of the driver.
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.
3.3 Encoder connection

3.5 Control signal connection
3.5.1 PUL, DIR Port: connection for start and stop command
Start and direction indication
1. At PUL on and DIR off, the motor is triggered to rotate
forward.When PUL is turned off, the motor decelerates and stops.
2. At PUL on and DIR on, the motor is triggered to rotate
reverse.When PUL is turned off, the motor decelerates and stops.
3.At PUL off, the motor stops.
3.5.2 ENA port: enable/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 an error state, it is automatically turned off. The level logic of the enable signal
can be set to the opposite.

3.5.3 ALM port: used for alarm and arrival output.
The ALM port is used to output the operating status of the driver to an external control circuit. When
the driver is in the error state and the normal working state, ALM outputs different optocoupler
levels.
In addition, ALM can be reused as brake control (break) signal through software adjustment, which
is used to control the brake switch of stepper servo motor with brake. Since the brake coil is an
inductive load, and the coil heating is serious when the motor is running, customers can select
special brake controller according to their needs to reduce the brake heating and improve life and
reliability.
Rtelligent provides solutions for dedicated brake controllers, examples are as follows:

4.2Motor direction selection
DIP SW5 is used to set the running direction of the motor under the initial pulse.
The “off” means that the motor direction is counterclockwise when inputting the initial pulse;
The “on” means that the motor direction is clockwise when inputting the initial pulse.
※The initial pulse is the testing pulse used when developing the driver software; Please refer to the
actual running direction of the motor.
4.3 Open/closed loop selection
DIP SW8 is used to set the driver control mode.
The “off” means the closed loop control mode;
The “on” means the open loop control mode and can be used to test the motor.
