The input of regenerative resistor capacity is over 0 and the servo drive does not connect to external regenerative resistor
  1. Check if it is connected to regenerative resistor.
  2. Check if the setting value of P1-53 is 0.
  1. If wishing to apply regenerative brake, please connect to external regenerative resistor. Then, check if the setting of P1-53 is correct.
  2. If not applying to regenerative brake, please set P1-53 to 0.
