33. Er.A34: Encoder communication check abnormal
Cause:
•
After power-on, read the initial phase information of the rotor of the 2500-PPR incremental
encoder error
Cause Conrming Method Corrective Action
1. The servo drive and
the servo motor are not
matching.
•
Check that the equipments you are
using are the IS620P series servo
drive and 20-bit servo motor (-U2***)
of Inovance. Meanwhile, check
whether H00-00 (motor SN) is 14000.
Replace the unmatched servo
drive or motor.
2. The encoder cable
breaks.
•
Check whether the encoder cable
breaks and whether connection of
the servo drive and connection of the
servo motor are secure.
Replace with a normal
encoder cable and secure the
cable connections.
34. Er.A35: Z signal lost
Cause:
•
The Z signal of the 2500-PPR incremental encoder gets lost or the edge of A, B signals
changes simultaneously.
Cause Conrming Method Corrective Action
1. The Z signal gets
lost because of faulty
encoder.
•
Use a normal encoder cable and
connect it. Then rotate the motor shaft
manually and check whether the fault
remains.
Replace the servo motor.
2. Poor contact or
incorrect connection
results in Z signal lost.
•
Rotate the motor shaft manually and
check whether the fault remains.
Connect the encoder cable
correctly or replace the cable.
