Keypad/Device Communication Abort

Hva betyr ErP ?

A communication abort has occurred between the keypad and the standard device (e.g., fault codes ErP0 through ErP19), indicating a failure in data exchange. The specific cause can vary. This prevents proper interaction with the device via the keypad and requires expert assistance for diagnosis.

• Loose or damaged cable connection between the keypad and the drive controller.
• Keypad not securely seated in its mounting slot or having bent pins on the connector.
• Electrical noise interfering with the serial communication between the keypad and the device.
• Faulty keypad unit or damaged communication port on the drive controller.
• Firmware incompatibility or corruption on either the keypad or the drive controller.

1. 1

   Disconnect and re-connect the keypad cable, ensuring it is fully seated and secured at both the keypad and the drive controller.

2. 2

   Carefully inspect the keypad connector pins and the drive's communication port for any physical damage, bent pins, or debris.

3. 3

   Check for external sources of electrical interference near the keypad cable, such as unshielded power cables or contactors.

4. 4

   Test with a known-good keypad if available, or attempt to connect to the drive using an alternative communication method (e.g., a PC via a service port).

5. 5

   Verify the firmware versions of both the keypad and the drive controller for compatibility, consulting the device manual if necessary.
