Fault

number Er_

Warning name

Cause of fault

Motor overload warning

Changed parameters need

to be re-powered to take

effect

Forward

overtravel

warning

Negative

overtravel

warning

External regenerative

resistor overload

External regenerative

resistor is too small

DI emergency brake

Homing timeout

Mechanical home point

offset error

Main circuit input lack

phase

The warning before the motor is about to fail, the warning

value is determined by P09_05

Changed parameters that need to be re-powered

Positive overtravel switch Pot terminal is valid

Negative overtravel switch Not terminal is valid

External regenerative resistor power is too small

The external regenerative resistor is less than the minimum

requirement by the driver;

Or parameter setting error

External emergency brake E_STOP terminal trigger

1. Home switch failure

2. Time limit to find home is too short

3. The high speed for searching home signal is too small

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.

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.
