A,B
Cause of the Problem
Solution
A
Regenerative power exceeds the limit.
Use an external regenerative
resistor that matches the
regenerative power capacity.
B
Alarm occurs although an external
regenerative resistor is used and the
temperature rise of the regenerative
resistor is small.
Correct parameter Pn600.
