Fault
number Er_
Warning name
Cause of fault
82
Motor overload warning
The warning before the motor is about to fail, the warning
value is determined by P09_05
83
Changed parameters need
to be re-powered to take
effect
Changed parameters that need to be re-powered
86
Forward
overtravel
warning
Positive overtravel switch Pot terminal is valid
87
Negative
overtravel
warning
Negative overtravel switch Not terminal is valid
90
External
regenerative
resistor overload
External regenerative resistor power is too small
91
External
regenerative
resistor is too small
The external regenerative resistor is less than the minimum
requirement by the driver;
Or parameter setting error
94
DI emergency brake
External emergency brake E_STOP terminal trigger
96
Homing timeout
1. Home switch failure
2. Time limit to find home is too short
3. The high speed for searching home signal is too small
97
Mechanical home point
offset error
1 When the home return mode parameter P16-09=6 or P16-
09=8 or P16-09=14, the mechanical home offset parameter
P16-14 is set to a value greater than 0.
2 When the home return mode parameter P16-09=7 or P16-
09=9 or P16-09=15, the mechanical home offset parameter
P16-14 is set to less than 0.
98
Main circuit input lack
phase
When the power input lack phase protection selects
parameter P09-00=1 (enable fault and warning), the driver
with rated power of 0.8kW, 1.0kW, 1.5kW, 3.0kW will
report a warning when the main circuit input voltage is
single-phase. .
Note: The reset method of warning: set P11-01=1 or use DI function 2.
