■ E3.102: Abnormal communication initialization of coprocessor
Cause:
Multi-core communication initialization fault or software version of cores not matching
Probable Cause Confirming Method Corrective Action
1. The FPGA software
version and the
software version of
CPU cores do not
match.
View the FPGA software version (2001-03h) and the
CUP0 software version (2001-04h) and the CUP1 software
version (2001-05h) via the keypad or the Inovance servo
commissioning software. Check whether the non-zero
value of the most significant bit is the same in the two
versions.
Contact Inovance for
technical support. Update
the software to make them
match.
2. The FPGA is faulty.
The fault persists after the servo drive is powered off and
on for several times.
Replace the servo drive.
■ E3.104: Abnormal communication or interrupt timeout of coprocessor
Cause:
Coprocessor or FPGA interrupt timeout, cyclic access among coprocessors timeout
Probable Cause Confirming Method Corrective Action
1. The FPGA is faulty.
The fault persists after the servo drive
is powered off and on several times.
Replace the servo drive.
2. The communication handshake between
the FPGA and the MCU is abnormal.
3. MCU interrupt times out.
■ E3.105: Internal program abnormal
Cause:
The total number of parameters is abnormal at EEPROM reading/writing operation.
The data range of parameters is abnormal, which generally occurs after software updates.
Probable Cause Confirming Method Corrective Action
1. An EEPROM fault occurs.
Check the causes according to the
method of E3.101.
Restore the default setting (2002-
20h=1), and power on the system
again.
2. The servo drive is faulty.
The fault persists after the servo drive is
powered off and on several times.
Replace the servo drive.
■ E3.106: abnormal communication of the main processor
To distinguish the fault symptom, the servo drive displays different internal fault codes under the same fault
code. You can view these internal fault codes in 200B-2Eh.
Cause:
Access between HOST and FPGA or between Host and coprocessor times out during power-on initialization.
Probable Cause Confirming Method Corrective Action
1. The FPGA is faulty.
The fault persists after the servo drive
is powered off and on several times.
Replace the servo drive.
2. The communication handshake between
the FPGA and the HOST is abnormal.
3. Access between HOST and coprocessor
times out.
