3. 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:
Check the speed limit
defined by H07.17 in the
torque control mode 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 control 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.
4. The motor speed
overshoots.
Check in the software tool
whether the speed feedback
exceeds the overspeed
threshold.
Adjust the gains or
mechanical operating
conditions.
5. The servo drive is faulty.
The fault persists after the
servo drive is powered off
and on again.
Replace the servo drive.
● E500.1: Speed feedback overflow
Cause:
The FPGA speed measurement overflows.
