CE Communications ErrorIf there is any breakdown in communication between the machine controller and the motor controller, CE flashes and the unit beeps once.
Some common causes of CE errors include:
· Conformal coating on serial communications pins between the machine controller and motor controller. After disconnecting power to the unit, try scraping this coating off the pins.
· Check the resistance values between the serial communications pins with the connectors in place. Make sure the harness does not have a bad connection.
· Check the quick disconnect at the motor terminal. The drive motor must be hooked up properly or a CE error will occur.
· Drive motor thermal protector has opened.
·Motor controller is not powered or fuse has opened. Replace motor controller.
