1. TROUBLESHOOTING FOR SERVO AMPLIFIER (DRIVE UNIT)
1 - 104
Alarm No.: E0 Name: Excessive regeneration warning
Alarm content
There is a possibility that regenerative power may exceed permissible regenerative power of built-in
regenerative resistor or regenerative option.
Detail
No.
Detail name Cause Check method Check result Action Target
E0.1 Excessive
regeneration
warning
(1) The regenerative
power exceeded 85%
of the permissible
regenerative power of
the built-in regenerative
resistor or regenerative
option.
Check the effective
load ratio. It is 85% or more. Reduce the
frequency of
positioning.
Increase the
deceleration time
constant.
Reduce the load.
Use a regenerative
option if it is not
being used. [A]
