4. The motor
cables are
grounded.
After ensuring the servo drive power cables
and motor cables are connected securely,
measure whether the insulation resistance
between the servo drive UVW cables and
ground cable (PE) is MΩ-level.
Replace the motor if the
insulation is poor.
5. The motor
UVW cables are
short-circuited.
Disconnect the motor cables and check
whether they are short-circuited and whether
burrs exist.
Connect the motor cables
correctly.
6. The motor is
damaged.
Disconnect the motor cables and measure
whether the resistance between motor cables
UVW is balanced.
Replace the motor if the
resistance is unbalanced.
7. The gain
setting is
improper and the
motor oscillates.
Check whether the motor oscillates or
generates a shrill noise during motor
startup and running. You can view current
feedback by using the drive Inovance servo
commissioning software.
Carry out gain adjustment.
8. The encoder
cable is
incorrectly
wired, corrosive,
or connected
loosely.
Check whether the encoder cable is used
according to the standard conguration.
Check whether the cable is aging, corrosive
or loose.
Turn off the S-ON signal, rotate the motor
shaft manually, and check whether 200B-12h
(electrical angle) changes as the motor
rotates.
Re-weld, fasten or replace
the encoder cable.
9. The servo
drive is faulty.
The fault persists after the motor cables are
disconnected and the servo drive is powered
on again.
Replace the servo drive.
10. Bleeder
resistor
overcurrent
Check whether external bleeder resistor
resistance value is small or the bleeder
resistor is short-circuited (P and C ends at
main circuit input terminal).
Select a new resistance
value and model of the
bleeder resistor.
Perform the wiring again.
E1.208: FPGA sampling operation timeout
Cause:
Find the cause based on the internal fault code (200B-2Eh).
Probable Cause Conrming Method Corrective Action
1. Communication
with the encoder
times out.
Internal fault code 200B-2Eh =
2208:
Encoder wiring is incorrect.
Connection of the encoder cable
becomes loose.
The encoder cable is too long.
Communication interference exists.
The encoder is faulty.
Use the recommended encoder
cable. If a non-standard cable is
used, check that it complies with
the specications and is a shielded
twisted pair cable.
Check whether the connectors at
both ends of the encoder are in good
contact.
Contact the manufacturer.
Do not bundle motor cables and
encoder cables together. Ensure the
servo motor and servo drive are well
grounded.
Replace the servo motor.
