Table 5–1 Fault codes
Fault Name Display Possible Cause Action
Overcurrent during
acceleration
E02.00 Grounded or short‑circuited
output circuit of the AC drive
Check whether the motor or relay contactor is
short‑circuited.
Auto‑tuning is not performed in
SVC or FVC control mode.
Set motor parameters according to the motor
nameplate and perform motor auto‑tuning.
Excessively short acceleration
time
Increase the acceleration time (F0‑17).
Inappropriate overcurrent stall
suppression
Ensure that overcurrent stall suppression (F3‑19)
is enabled.
If the value of F3‑18 (overcurrent stall suppression
level) is too large, adjust it to a level between
120% and 160%.
If the value of F3‑20 (overcurrent stall suppression
gain) is too small, adjust it to a level between 20
and 40.
Inappropriate customized torque
boost or V/f curve
Adjust the customized torque boost or V/f curve.
Startup of a running motor Use flying start or restart the motor after the
motor stops.
External interference to the AC
drive
View the fault records to check whether the fault
current has ever reached the overcurrent
suppression level (F3‑18). If not, check for external
interference source. If no external interference
source is found, the driver board or Hall device
might be damaged. Contact Inovance for
replacement.
