Probable Cause Conrming Method Corrective Action
5. The servo
drive is faulty.
Check whether 200B-1Bh (Bus voltage) is within the
following specications:
380 V drive: 200B-1Bh < 350 V
The fault persists after the power supply on the power
supply side is powered off and on several times.
Replace the
servo drive.
E1.500: Motor overspeed
Cause:
The actual speed of the servo motor exceeds the overspeed threshold.
Probable Cause Conrming Method Corrective Action
1. The UVW phase
sequence of the
motor cables is
incorrect.
Check whether the servo drive power
cables are in the same phase sequence
as the servo drive UVW cables and the
motor UVW cables.
Connect the UVW cables according to the
correct sequence.
2. The setting
of 200A-09h is
incorrect.
Check whether the overspeed threshold
is smaller than the actual maximum
motor speed.
Overspeed threshold = 1.2 times
maximum motor speed (200A-09h = 0).
Overspeed threshold = 200A-09h
(200A-09h ≠ 0, and 200A-09h < 1.2 times
maximum motor speed).
Re-set the overspeed threshold according
to the actual mechanical requirement.
3. The input
reference is higher
than the overspeed
threshold.
Check whether the motor speed
corresponding to the input reference
exceeds the overspeed threshold.
Position control mode:
In CSP mode, view the gear ratio
6091-01h/6091-02h to check the
position reference increment for a single
synchronous cycle and convert it to
speed.
In PP mode, view the gear ratio
6091-01h/6091-02h and check the value
of 6081h (prole velocity).
In HM mode, view the gear ratio
6091-01h/6091-02h, and determine
6099-01h and 6099-02h.
In speed control mode,
view the gear ratio 6091-01h, and the
values of 60FFh (Target velocity) and
607Fh (Max prole velocity).
Torque control mode:
View the speed limit 607Fh in torque
control.
Position control mode:
CSP: Decrease the position reference
increment for a single synchronous cycle,
and the host controller needs to increase
the position ramp additionally when
generating references.
PP: Decrease the value of 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 the
actual conditions.
Speed mode:
Decrease the target velocity, speed limit
value, gear ratio. In PV mode, increase
the speed ramp 6083h and 6084h; in CSV
mode, the host controller needs to increase
speed ramp additionally.
Torque control mode:
Set a speed limit value smaller than the
overspeed threshold.
4. The motor speed
overshoots.
Check whether the actual speed exceeds
the overspeed threshold through the
drive Inovance servo commissioning
software.
Adjust the gain or mechanical conditions.
5. The servo drive
is faulty.
The fault persists after the servo drive is
powered on again.
Replace the servo drive.
