Chapter 1 Overview

1.1 Product Introduction

CL57Y adopts a new generation of 32-bit DSP control technology and power angle control technology. The maximum speed can reach 3000rpm, and the high-speed torque attenuation is far lower than that of the ordinary open-loop driver, which can greatly improve the high-speed performance and torque of the stepper motor. It can effectively reduce the heating and vibration of the motor, thus improving the processing efficiency and accuracy of the machine. The driver adopts load-based current control technology, which can effectively reduce motor heat and prolong motor service life. The built-in position and alarm output signals of the driver are convenient for the upper computer to monitor and control. Position out of tolerance alarm function guarantee.

• The current size is intelligently adjusted according to the load condition.
• Can drive 23/24 series stepper motor.
• The optocoupler isolates the differential signal input.
• The impulse response frequency is up to 200KHz.
• Voltage input range: DC24-50V.
• With over current, over voltage, under voltage, position over error protection.

1.2 Application Field

This product is suitable for a variety of large automation equipment and instrument applications. For example: engraving machine, special industrial sewing machine, stripping machine, marking machine, cutting machine, laser phototypesetting, plotter, CNC machine tools and other automation equipment and instruments.

Chapter 3 Installation

3.1 Mounting Dimension

Diagram Description: The mounting dimensions are shown in two views. The side view depicts a rectangular block with a height of 118mm, a width of 24.2mm, and a flank depth of 4.6mm, indicating mounting holes. The front/top view shows a block with a height of 111.5mm, a width of 75.7mm, and a depth of 27.9mm, featuring four ø3.5mm mounting holes on the head. Installation size is in millimeters.

3.2 Installation Methods

When installing the driver, please use the upright side installation to form strong air convection on the driver surface. If necessary, install a fan close to the driver to force the heat to dissipate to ensure that the driver works within the reliable operating temperature range (the reliable operating temperature of the driver is usually within 50°C, and the operating temperature of the motor is within 80°C).

Diagram Description: The diagram illustrates a recommended installation setup for multiple stepper drivers to ensure adequate cooling. Drivers are mounted vertically with sufficient spacing: at least 50mm between drivers and at least 30mm from side walls. Air inlets are shown at the bottom and air outlets at the top, indicating a forced convection cooling system.

4.3 Input/Output Port Operation

The CL57Y driver has three digital inputs, photoelectric isolation, and the signal supports 5V-24V input. When the input signal is higher than 24V, the series current limiting resistance is required at the signal input end. The specific wiring diagram is as follows:

4.3.1 Input Signal

Diagram Description (Common Positive Connection): Shows a 5-24V VCC source connected to the positive terminals of Pulse (PU+), Direction (DR+), and Enable (MF+) signals. The input signals (Pulse, Dir, MF) are then connected to the respective negative terminals (PU-, DR-, MF-) of the CL57Y driver through optocouplers.

Diagram Description (Common Negative Connection): Shows a 5-24V VCC source connected to the common terminal of the CL57Y driver. The input signals (Pulse, Dir, MF) are connected to the respective positive terminals (PU+, DR+, MF+) of the driver through optocouplers.

Diagram Description (Differential Connection): Shows the Pulse (PU), Direction (DR), and Enable (MF) signals connected directly to the corresponding differential input terminals (PU+/PU-, DR+/DR-, MF+/MF-) of the CL57Y driver, with optocouplers on each signal line.

4.3.2 Output Signal

The driver output signal is isolated by an optocoupler and the drive current is max 50mA.

Diagram Description (Common Negative Connection): Illustrates the driver's output signals (e.g., PEND, ALM) connected to an actuator. The driver's output uses optocouplers. The actuator is powered by +5-24V and includes a series resistor (R). The common negative connection is shown for the driver and actuator.

Diagram Description (Independent Termination Method): Shows the driver's output signals connected to an actuator. The actuator is powered by +5-24V and includes a series resistor (R). The connection is made with the positive terminal of the actuator connected to the driver's output and the negative terminal connected to ground.

4.4 Signal Input Timing Diagram

CL57Y driver: To avoid abnormal operation of the driver control motor, please refer to the following diagram for the timing diagram of the input signal:

Diagram Description: The timing diagram shows waveforms for the Pulse (PU), Direction (DR), and Enable (MF) input signals. The PU signal is depicted as a pulse with specified rise/fall times and a minimum pulse width. The DR signal shows a transition. The MF signal is shown as a low-level signal. Key timing parameters indicated are: PU pulse width > 2.5µs, DR setup time < 1µs, and MF hold time > 125µs.

Chapter 5 Driver Status Indicators

The CL57Y driver has an alarm prompt. After the driver alarms, the alarm indicator state indicates the alarm information of the driver. The specific alarm information is shown in the following table:
