Solution
The input reference exceeds
the overspeed threshold.
Check whether the motor
speed corresponding to the
input reference exceeds the
overspeed threshold.
● Position control mode:In
CSP mode, check the gear
ratio 6091.01h/6091.02h to
determine the position
reference increment for an
individual synchronization
period and convert it to the
speed information.In PP
mode, check the gear ratio
6091.01h/6091.02h and
determine the 6081h
(Profile velocity).In HM
mode, check the gear ratio
6091.01h/6091.02h, and
determine 6099.01h and
6099.02h.
● Speed control mode:Check
the gear ratio (6091h),
target velocity (60FFh),
speed limits (H06.06 to
H06.09), and the maximum
profile velocity (607Fh).
● Torque control mode:View
the speed limit defined by
H07.17 and check the
corresponding speed limit.
● Position control mode:CSP:
Decrease the position
reference increment per
synchronization period.
The host controller should
cover the position ramp
when generating
references.PP: Decrease
the value 6081h or increase
the acceleration/
deceleration ramp (6083h,
6084h).HM: Decrease
6099.01h and 6099.02h or
increase the acceleration/
deceleration ramp (609Ah).
Decrease the gear ratio
according to actual
conditions.
● Speed mode:Decrease the
target velocity, speed limit,
and gear ratio. In PV mode,
increase the speed ramp
(6083h and 6084h). In CSV
mode, the host controller
should cover the speed
ramp.
● Torque control mode:Set
the speed limit to a value
lower than the overspeed
threshold.
The motor speed
overshoots.
Check whether the speed
feedback exceeds the
overspeed threshold by
using Inovance servo
commissioning software.
Adjust the gain or
mechanical running
conditions.
5. The servo drive is faulty.
The fault persists after the
servo drive is powered off
and on again.
Replace the servo drive.
