CW1108 stepper motor driver

1、 Product Introduction

1. Overview

The CW1108 stepper motor driver is a novel subdivision driver developed by our factory by absorbing new and high-speed electronic technologies on the basis of the original driver. This driver adopts advanced technology and has the advantages of low noise, high efficiency, wide voltage range, flexible and diverse settings, especially smooth operation and accurate positioning, which are the biggest features of this driver. In addition, this driver has complete protection functions and has power-off phase function. There are 16 types of micro step subdivision, with a maximum subdivision score of 1/256 (51200 steps per revolution); Its working current range is 0.5A-8A, with a total of 16 output currents and a current resolution of approximately 0.4A. It has protection functions such as automatic half current, self check, overvoltage, undervoltage, and overcurrent. This driver is powered by AC, and it is recommended to operate at a voltage of 110VAC-220VAC, with a voltage not exceeding 240VAC and not lower than 80VAC.

2、 Parameter settings

1. Current setting

Dial switch: ON=0 OFF=1

2. Half flow setting

If the upper control computer does not send a step signal for half a second, the driver will automatically enter a power-saving half current state, and the phase current of the motor winding will be reduced to half of the set value. In this state, the power consumption of the motor and driver is reduced, but the output torque of the motor is also correspondingly reduced. Automatically restore the rated output current when the next pulse arrives.

3. Subdivision setting

Dial switch: ON=0 OFF=1

3、 Interface wiring instructions

1. Control signal interface

If the input signal voltage amplitude is greater than 5V, the input terminal needs to be connected in series with a current limiting resistor (refer to the control signal interface circuit diagram).

2. Strong electrical interface

3. Control signal interface circuit

Detailed description of signal interface: The interface circuits inside the CW1108 stepper motor driver are all isolated by optocoupler signals, and R in the figure is an external current limiting resistor. The connection method is differential connection, with good anti-interference performance.

5、 Appearance and installation dimensions (unit: mm (inch), 1 inch=25.4mm)

The external dimensions of the driver are 195 × 107 × 81mm, as shown in the external dimension diagram. Pay attention to leaving more than 10CM of space for heat dissipation. During installation, it should be tightly attached to the metal cabinet to facilitate heat dissipation.
