Description of Fault Codes
‑33‑
Parameter attribute initialization check error.
Cause
Confirming Method
Solution
Parameter attribute
initialization check error
Check that H0A.99 = AA5C.
If the problems persists after
the servo drive is powered
off and on several times,
replace the servo drive.
● E102.0: FPGA communication establishment error
Cause:
The communication between MCU and FPGA cannot be established.
Cause
Confirming Method
Solution
The communication
between MCU and FPGA
cannot be established.
The fault persists after the
servo drive is powered off
and on repeatedly.
Replace the servo drive.
● E102.1: FPGA initialization start error
Cause:
FPGA failed.
Cause
Confirming Method
Solution
FPGA cannot start.
The fault persists after the
servo drive is powered off
and on repeatedly.
Replace the servo drive.
● E102.8: FPGA and MCU version mismatch
Cause:
FPGA and MCU version mismatch.
Cause
Confirming Method
Solution
The software versions of
MCU and FPGA are
inconsistent.
1. Check whether the MCU
version (H01.00) is 9xx.x
(the fourth digit displayed
on the keypad is 9);
2. Check whether the FPGA
version (H01.01) is 9xx.x
(the fourth digit displayed
on the keypad is 9).
Contact Inovance for
technical support. Update
the FPGA or MCU software.
● E104.1: MCU running timeout (MCU break down)
Cause:
The access to MCU times out.
