   1.3 Safety instructions

  The transportation, installation, use or maintenance of this product must be carried out by personnel who are professionally qualified and familiar with the above operations.

  In order to minimize potential safety hazards, you should comply with all local and national safety regulations when using this equipment. Different areas have different safety regulations. You should ensure that the equipment is installed and used in accordance with your Regional specification.

  System errors can also result in equipment damage or personal injury. We do not guarantee that this product is suitable for your specific application and we cannot be held responsible for the reliability of your system design.

  Be sure to read all relevant documents before installation and use. Improper use may result in equipment damage or personal injury. Please strictly observe the relevant technical requirements during installation. Be sure to confirm the grounding of each device in the system. Ungrounded systems cannot guarantee safety during using.

  Some components inside the product may be damaged by external static electricity. Before touching the product, the operator should ensure that there is no static electricity and avoid contact with objects that are easily electrostatically charged (chemical fiber, plastic film, etc.).

  If your device is placed in the control cabinet, please close the control cabinet cover or the door during operation, otherwise it may cause equipment damage or personal injury.

  It is strictly forbidden to hot plug the cable while the system is running. The arc generated by hot plugging may cause harm to operators and equipment.

  Wait at least 5 seconds to contact the product or remove the wiring after turning off the power. Capacitive devices may still store dangerous electrical energy after power failure and require some time to release. To ensure safety, you can measure it with a multimeter before touching the product.

  Please observe the important safety instructions presented in this manual, including clear warning symbols for potential safety hazards, and read and become familiar with these instructions before installation, operation and maintenance. The purpose of this paragraph is to inform users of the necessary safety instructions and to reduce the risk of personal injury and equipment safety. Miscalculations of the importance of safety prevention can cause serious damage or render the device unusable.

  2. Driver installation

  The narrow side of the driver ‘s heat sink is the mounting surface and is installed in the cabinet. It should be installed in the mounting hole of the driver with M4 screws.

  The power portion of the driver generates heat, and forced air cooling is required to operate the driver at maximum power.

  Do not install the driver in a space where there is no air flow or place it around equipment that can cause ambient temperatures above 40 °C, and do not place the driver in a humid environment or where metal chips can easily fall into the driver.

  3 Connections

   3.1 Connecting the power supply

  Connect the AC power supply with the attached connector as shown below. Connect the live (L) and neutral (N) wires with AWG16 wires and the ground wire (G) with AWG14 wires.

  Do not remove the power connector while the power is on! If the operating environment's power supply voltage is higher than the normal voltage, a transformer is required to bring the voltage back to the normal range.

  The 3R110 drive contains a 10A snap-off fuse.

   3.2 Connecting the motor

  Warning: When connecting the motor to the driver, please make sure that the power of the driver is off. The motor cannot be disconnected while the driver is energized. Do not connect the motor leads to the ground or power supply.

  By connecting the motor leads to the U, V, and W terminals of the drive, you can change the lead sequence of any set of windings to change the direction of the motor.

  3.3.1 Enable Input

  The EN input enables or disables the power section of the driver. The signal input is photoelectric isolated and accepts 5-24 VDC single-ended or differential, and the maximum signal can reach 28V.

  When the EN signal is suspended or low (optocoupler is not conducting), the driver is enabled and the motor is running normally; when the EN signal is high (optocoupler is on), the power supply of driver is partially turned off and the motor is not energized.

  The EN input can be used to restart the drive when the motor is in an error state. First, the existing fault is eliminated from the application system, and then a falling edge signal is input to the EN terminal. The driver can restart the power section and the motor is excited.

  3.3.2 Alarm output

  The OUT port is an opto-isolated output with a maximum withstand voltage of 30VDC and a maximum saturation current of 100mA.

  When the driver is working normally, the output optocoupler does not turn on. Detailed parameters of 3R110 three-phase AC stepper motor driver
