Cause and
correction
Assumed cause Remedy Prevention
The load inertia is too large. Or, the
Servomotor rotation speed is too high
to absorb the regenerative energy
within the specified deceleration time.
Check the operation pattern (velocity
monitor). Check the Regeneration
Register load rate and the excessive
regeneration warning, and perform
the following accordingly.
• Increase the capacity of the
Servomotor and Servo Drive.
• Increase the deceleration time.
• Reduce the Servomotor rotation
speed.
• Use an External Regeneration
Resistor.
• Set the Regeneration Resistor
Selection (3016 hex) to 2.
Check the items given for corrections
in advance and implement
countermeasures as required.
This Regeneration Resistor cannot be
used for continuous regenerative
braking. (The operating limit of the
external resistor is limited to a 10%
duty.)
Set the Regeneration Resistor
Selection (3016 hex) to 2.
Set the Regeneration Resistor
Selection (3016 hex) to 2.
