10. Er.136: Data check error or no parameter stored in the motor ROM
Cause:
•
When the servo drive reads parameters from the encoder ROM, it nds that no parameters
are saved there or the parameter value is inconsistent with the agreed value.
Cause Conrming Method Corrective Action
1. The servo drive model
and the motor model do
not match.
•
View the servo drive and motor
nameplates and check that the
equipment you are using is the
IS620P series servo drive and 20-bit
servo motor (-U2***) of Inovance.
Replace the unmatched servo
drive or motor. If you use the
IS620P series servo drive and
20-bit servo motor of Inovance,
ensure that H00-00 = 14000.
2. A parameter check
error occurs or no
parameter is stored in
the serial encoder ROM
memory.
•
Check whether the cable you use is
standard conguration of Inovance.
For the cable specication, refer to
Chapter 3 Wiring of Servo System.
The cable must not scratch, break or
be in poor contact. The cable must
be connected reliably.
•
Measure the signals PS+, PS-
, +5V and GND at both ends of
the encoder cable and observe
whether the signals at both ends are
consistent. For denition of signals,
see Chapter 3 Wiring of Servo
System.
•
Ensure that you use the
encoder cable congured by
Inovance as standard.
•
Ensure that the cable is
connected to the motor
securely and tighten the
screw on the drive side.
If necessary, use a new
encoder cable.
•
Never bundle the encoder
cable and power cables (R/
S /T, UVW). Connect them
separately.
3. The servo drive is
faulty.
•
The fault remains after the servo
drive is powered on again.
Replace the servo drive.
11. Er.200: Overcurrent 1
Cause:
•
Any phase feedback current is larger than the overcurrent level of the servo drive.
