What Er13-1 means

Main circuit undervoltage p. 258

Common causes

  • The DC voltage of the drive main circuit is higher than the specified voltage. p. 258
  • 1. The grid voltage is too low. p. 258
  • 2. The buffer relay is not closed. p. 258
  • 3. The drive output power is too high. p. 258
  • 4. The internal DC voltage detection circuit of the drive is damaged. p. 258

What to do

  1. 3120-0D01h p. 258
  2. 1. Ensure the grid input voltage is within the allowed range. 2. Repower on the drive. Ensure the buffer relay is closed. If the buffer relay is closed, there is a sound indicating actuation. p. 258
  3. 3. Check R0.07 when the drive is disabled. If it is abnormal and does not match the grid input voltage, replace the drive. p. 258
