Interface & Wiring Description
Item Name - No. | Interface Identification | Description |
Motor Status Indicator - 1 |
| Red LED ON: The motor is in the disabled state (default state after power-up)； Green LED ON: The motor is in the enabled state； Red LED Flashing: A motor fault is detected. Refer to the feedback information to identify the fault type； Green LED Flashing: The motor failed the power-on self-check. Please save the startup log information and contact customer support.
|
Terminal Resistor Switch - 2 |
| The motor is equipped with a built-in terminal resistor, which is disabled by default. |
Debug Serial Port - 3 |
| Connect the motor to a PC via a GH1.25 3-pin cable using a USB-to-CAN debugging tool (or a general USB-to-Serial adapter). The Debug Assistant software can be used for parameter configuration, firmware upgrades, and other debugging operations. |
Power Connector - 4 (with CAN Communication Terminal) |
| 1. Connect the power supply through an XT30 (2+2)-F power connector. The rated voltage is 24V for motor power input. 2. Connect external control devices through the CAN communication terminals to receive CAN control commands and transmit motor status feedback. 3. The motor is equipped with two power connectors. Either connector can be used independently, or multiple motors can be connected in series to simplify cable routing. |
Power Connector - 5 (with CAN Communication Terminal) |
