E1.104: Abnormal communication or interrupt timeout of coprocessor
Cause:
Coprocessor or FPGA interrupt timeout, cyclic access among coprocessors timeout
Probable Cause Conrming 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.
E1.107: main processor communication loss
Cause:
Cyclic handshake communication between the main processor and coprocessor is lost.
Probable Cause Conrming Method Corrective Action
Internal
communication
failure
The fault persists after the servo drive is
powered off and on several times.
Replace the servo drive.
E1.108: parameter storage fault
Cause:
Parameter values cannot be written to EEPROM.
Parameter values cannot be read from EEPROM.
Probable Cause Conrming Method Corrective Action
1. Parameter writing is abnormal.
Modify a parameter, power on
the servo drive again and check
whether the modication is
saved.
If the modication is
not saved and the fault
persists after the servo
drive is powered off and
on several times, replace
the servo drive.
2. Parameter reading is
abnormal.
E1.110: Setting error of frequency-division pulse output
Cause:
The number of frequency-division output pulses is excessively large.
Probable Cause Conrming Method Corrective Action
The number of
frequency-division
output pulses is
excessive.
View the H05-17 value of a corresponding
axis:
The H05-17 value exceeds the encoder
resolution.
Modify the H05-17 value.
E1.111: abnormal 2000h/2001h group parameter
Cause:
The total number of parameters changes, which generally occurs after software updates.
The actual parameter values of group 2000 or 2001 exceed the limit, which generally occurs
after software updates.
