Description of Fault Codes
‑39‑
When reading parameters in the encoder ROM, the servo drive detects that no
parameters are saved there or parameter values are inconsistent with the
setpoints.
Cause
Confirming Method
Solution
1. The servo Servo drive
model does not match the
motor model.
View the servo drive and
servo motor nameplates to
check whether the SV670P
series servo drive and servo
motor are used.
Replace the servo drive and
motor.
2. A parameter check error
occurs or no parameter is
saved in the ROM of the
serial incremental encoder.
1. Check whether the
encoder cable provided
by Inovance is used. For
cable specifications, see
"Matching Cables". The
cable must be connected
securely without
scratching, breaking or
poor contact.
2. Measure signals PS+, PS‑,
+5V and GND on both
ends of the encoder cable
and observe whether
signals at both ends are
consistent. For signal
assignment, see Chapter
"Wiring" in SV680P Series
Servo Drive Hardware
Guide.
1. Use the encoder cable
provided by Inovance.
Ensure motor terminals
and servo drive screws
are connected securely.
Use a new encoder cable
if necessary.
2. Route encoder cables and
power cables (R/S/T, U/V/
W) through different
routes.
3. The servo drive is faulty.
The fault persists after the
servo drive is restarted.
Replace the servo drive.
● E136.1: Encoder ROM motor parameter read error
Cause:
■ The encoder cable is disconnected.
■ A communication error occurs on the encoder due to interference.
