5. Operation
Once the kit is correctly installed and wired, ensure your control system is configured to send appropriate pulse and direction signals to the CL57T driver. The closed-loop system will monitor the motor's position via the encoder and adjust current to maintain accuracy, preventing step loss. Always verify DIP switch settings match your application requirements before initiating operation.
6. Troubleshooting
The CL57T driver incorporates built-in protection features to improve reliability. The red LED on the driver indicates operational status and can blink in specific sequences to signal errors. Refer to the table below for common error indications and their corresponding troubleshooting steps.
