What Er02-c means

Encoder fault--No data in encoder EEPROM p. 257

Common causes

  • Encoder fault--No data in encoder EEPROM p. 257
  • If the motor is used with a communication encoder, no data is found in the encoder EEPROM when the motor attempts to read data from it during power-on. p. 257

What to do

  1. 7300-020Ch p. 257
  2. 1. Select the motor model based on the setting of P0.00 and execute the operation of writing data to the encoder EEPROM through P4.97. 2. Mask this fault through P4.98. The motor parameters in the drive EEPROM are used for initialization. p. 257
