Description of Fault Codes
‑35‑
Cause
Confirming Method
Solution
1. The product (motor or
servo drive) code does not
exist.
Read the nameplates of the
servo drive and motor to
check whether SV670N
series servo drive and 23‑bit
servo motor are used.
Meanwhile, check whether
H00.00 (motor code) is set to
14101.
If the motor code is
unknown, set H00.00 to
14101 when the SV670N
series servo drive and 23‑bit
servo motor are used.
Check the servo drive code
(H01.02) to see whether this
servo drive code exists.
If the drive code is absent,
set the servo drive model
correctly according to the
nameplate.
2. The power rating of the
motor does not match that
of the servo drive.
Check whether the servo
drive code (H01.02) matches
the serial‑type motor code
(H00.05).
Replace the unmatched
products.
● E120.1: Unknown motor model
Cause:
The servo drive detects the motor model defined by H00.00 during initialization
upon power‑on. If the motor model does not exist, E120.1 occurs.
Cause
Confirming Method
Solution
The motor model defined by
H00.00 is abnormal
Check whether the value of
H00.00 matches the used
motor.
Rectify the value of H00.00.
● E120.2: Unknown drive model
Cause:
The servo drive detects the servo drive model defined by H01.10 during
initialization upon power‑on. If the servo drive model does not exist, E120.2
occurs.
Cause
Confirming Method
Solution
H01.10 is incorrect
Check the value of H01.10.
Disable servo drive model
auto detection and set H01‑
10 to a proper value
manually.
● E120.5: Motor and drive current mismatch
Cause:
The rated output of the servo drive is far higher than the rated current of the
motor. You must use a servo drive of lower rated output or a motor with higher
rated current.
