Cause Remedy
A Regenerative power exceeds the allowable
value. Use an external regenerative resistor that
matches the regenerative power capacity.
B Alarm occurs although an external regener-
ative resistor is used and the temperature
rise of the regenerative resistor is small. Correct parameter Pn600.
