Note: The PID feedback input is not within the range set by F13.27 [Disconnection Detection Upper Limit] and F13.28 [Disconnection Detection Lower
Limit], and is reported after exceeding the setting value of F13.26 [Disconnection Detection Time]. The fault.
The motor action can be detected when the fault is detected by F13.25 [PID feedback disconnection processing].

Reason
Read and write parameters to receive interference
during EEPROM operation
E. EEPROM hardware has failed
Reason
Braking resistor resistance is small
Brake unit failure
Reason
communication fail
The drive model or software version does not match
the keyboard storage parameters.
Keyboard parameter copy hardware failure
Reason
Improper encoder ratio setting
Reason
ABZ encoder wiring is incorrect, or disconnection
occurs
Reason
There is a strong interference source that causes
problems with data transmission.
The resolver card is not wired correctly, or the cable
is broken.
Reason
The resolver card is not wired correctly, or the cable
is broken.
Reason
ABZ encoder wiring is incorrect, or disconnection occurs
The motor electromagnetic brake is in the brake state
Reason
The spindle encoder is not wired correctly or a wire break
occurs.
The motor electromagnetic brake is in the brake state
Reason
Spindle encoder Z pulse error exceeds the set value
Reason
Drive output current exceeds upper and lower limits during
self-learning
Reason
Reason
Reason
Excessive load
ACCE and DECE time is too short
Improper setting of speed deviation detection parameters
The motor electromagnetic brake is in the brake state

Countermeasures
Re-read and write parameters after checking and
eliminating interference sources
Power off and restart the drive to confirm whether the fault
will still occur.
The fault still occurs after restarting, seeking technical
support from the manufacturer.
Countermeasures
Replace the braking resistor with a larger resistance
Seek technical support from manufacturers
Countermeasures
Confirm that the keyboard and drive are connected properly,
and re-copy after plugging and unplugging.
Re-copy the parameters before downloading to the drive
Replace the keyboard and still can't copy and seek technical
support from the manufacturer.
Countermeasures
Reset F02.35 [transfer ratio numerator] and F02.36 [gear
ratio denominator] so that the ratio is in the range of
0.01~100
Countermeasures
Check the encoder wiring for problems
Countermeasures
Check the grounding of the whole machine to eliminate the
interference source
Check if there is a problem with the resolver wiring
