Cause Possible Solution
Encoder fault
E 20.00
Encoder wire-break
occurs.
Repair the wire-break.
Confirm the wiring of PG card is correct.
Confirm the actual encoder pulses per
revolution matches the setting value of F1-27
(Encoder pulses per revolution).
Confirm the wiring of signal AB is correct.
E 20.01
The encoder is
faulty.
E 20.02
Encoder wire-break
occurs.
E 20.03
The synchronous
motor no-load auto-
tuning encoder is
faulty.
E 20.04
The synchronous
motor no-load auto-
tuning encoder is
faulty.
E 20.06
The synchronous
motor auto-tuning
encoder is faulty.
E 20.07
The synchronous
motor no-load auto-
tuning encoder is
faulty.
E 20.08
The synchronous
motor no-load auto-
tuning encoder is
faulty.
E 20.09
The synchronous
motor with-load
auto-tuning encoder
is faulty.
Check feedback signal Z and the wiring of PG
card.
E 20.10
The synchronous
motor encoder is
faulty.
E 20.11
The asynchronous
motor FVC no-load
auto-tuning encoder
is faulty.
Confirm the encoder is correctly connected.
Confirm the actual encoder pulses per
revolution matches the setting value of F1-27
(Encoder pulses per revolution).
E 20.12
The error between
encoder feedback
speed and speed
estimated by SVC is
too large.
Confirm the encoder is correctly connected.
Confirm the motor parameters is correctly set.
Confirm motor auto-tuning is performed.
E 20.13
The resolver wire-
break occurs.
Confirm the resolver is correctly connected.
