How Do I Resolve The Monarch E20 Error?

Today, let's look at a common fault code in Monarch systems - E20.

When an E20 fault occurs, focus on the following checks:

First, inspect the encoder for any looseness or misalignment.

Second, check the encoder wiring for broken wires, damaged insulation, or electromagnetic interference.

Third, pay close attention to the connection between the PG card and the main board.
Make sure the connector is secure, and check whether the PG card or the main board itself is faulty.

Additionally, verify that the motor parameters match the encoder parameters.
If the parameters are correct, proceed to check the hardware step by step as mentioned above.
