Attention: Please read this manual carefully before using the drive.
1 Introductions & Features
The Y series closed-loop drivers are divided according to the driving power, which are CL57Y,
CL86Y.This Closed Loop Stepper Drive offers an alternative for applications requiring higher
performance and higher reliability than open loop stepper system, and it remains cost-effective. The
matched stepper motors are NEMA17, 23 and 24 combined with an internal encoder which is used to
close the position, velocity and current loops in real time. Its great features of quicker response and
no hunting make this closed loop stepper drive ideal for applications such as bonding and vision
systems in which rapid motions with a short distance are required and hunting would be a problem.
And it is ideal for applications where the equipment uses a belt-drive mechanism or otherwise has low
rigidity and you don't want it to vibrate when stopping. And features are showing below:
A new generation of 32-bit DSP control technology
Input voltage range: DC24 ~ 50V, AC20 ~ 80V / DC30 ~ 110V
The highest impulse response frequency is 200KHz
Low torque attenuation, up to 3000rpm
Built-in positioning and alarm output for easy detection and control
Intelligently regulate current, reduce vibration, noise and heat, and increase efficiency by 35%
With single and double pulse selection function, the factory default is: pulse + direction
control
Excellent high-speed performance and rigidity, perfect combination of servo and stepping

MF-
When it is active
（low level）
, the motor coil current is turned off, the driver stops
working, and the motor is in a free state.
Pend+
When the drive has finished a given pulse, the in-position signal is valid (output
optocoupler is on). Pend+ is connected to the pull-up resistor to the positive
terminal of the output power supply. The maximum current is 50mA.
Pend-
Pend- is connected to the negative terminal of the output power supply.
ALM+
When overcurrent, overvoltage, undervoltage or position error alarm, the alarm
signal is valid (output optocoupler is on). ALM+ is connected to the pull-up
resistor to the positive terminal of the output power supply. The maximum drive
current is 50mA.
ALM-
ALM- is connected to the negative terminal of the output power supply.

4 Wiring
The CL57Y、CL86Y can accept differential and single-ended inputs (including open-collector and PNP
output). The CL57Y、CL86Y has 4、5 optically isolated logic inputs which are located on connector P1 to
accept line drive control signals. These inputs are isolated to minimize or eliminate electrical noises
coupled with the drive control signals. Recommend using line drive control signals to increase noise
immunity for the drive in interference environments.
A complete closed loop stepper system should include a closed loop motor, a drive, a power supply
and a controller (pulse generator). The typical connection is shown as figure 3.
