Inovance MD800 Series Function Guide

List of Fault Codes
The following faults may occur during the use of the AC drive. Troubleshoot the faults according to the
solutions described in the following table.
Table –52 Fault codes
Fault Name
Display
Possible Cause Solution
Fault Type
STO product model
identification error
E01.06
The hardware is faulty.
Check the AC drive nameplate to confirm whether
the AC drive has the STO function. If not, contact the
technical support personnel.
Axis fault
AC drive axis type
identification
setting error
E01.07
The hardware is faulty.
Check the AC drive nameplate to confirm the axis
type (single-axis or dual-axis) of the AC drive.
Axis fault
Overcurrent during
acceleration
E02.04
1 A grounding fault or
short circuit exists in the
output circuit of the AC
drive.
2 The SVC control mode
is adopted, and motor
auto-tuning is not
performed.
3 The set acceleration
time is too short.
4 The overcurrent stall
suppression setting is
improper.
5 The customized torque
boost or V/f curve is
improper.
6 The motor is started
while rotating.
7 The AC drive suffers
external interference.
1 Check the motor and the relay contactor
and make sure that they are not short-
circuited.
2 Set the motor parameters according to the
motor nameplate and perform motor auto-
tuning.
3 Increase the acceleration time (F0-17).
4 Ensure that overcurrent stall suppression
(F3-19) is enabled.The overcurrent stall action
current (F3-18) is too high. Adjust it to a value
between 120% and 160%.The overcurrent stall
suppression gain (F3-20) is too low. Adjust it
to a value between 20 and 40.
5 Adjust the customized torque boost or V/f
curve.
6 Enable the flying start function or start the
AC drive after the motor stops.
7 Check whether the fault current reaches the
overcurrent stall suppression current (F3-18)
by viewing the fault log. If not, the fault is
possibly caused by external interference. In
this case, find out the external interference
source and rectify the fault.If no external
interference source is found, the drive board
or Hall device may be faulty. In this case,
contact the manufacturer for replacement.
