: IPM over-current
Cause
Confirmation
Solution
Short of driver output wire
Short of driver output wire, whether
short circuit to PG ground or not
Assure driver output wire no short
circuit, assure motor no damage
Abnormal wiring of motor
Check motor wiring order
Adjust motor wiring sequence
Short of IGBT module
Cut off driver output wiring, make
srv_on available and drive motor,
check whether over-current exists or
not
replace the driver with a new one
Short of IGBT module
/
replace the driver with a new one
abnormal setting of control
parameter
Modify the parameter
Adjust parameter to proper range
abnormal setting of control
command
Check control command whether
command changes too violently or
not

: driver over-heat
Cause
Confirmation
Solution
the temperature of power
module have exceeded
upper limit
Check driver radiator whether
the temperature is too high or
not
Strengthen cooling conditions, promote
the capacity of driver and motor, enlarge
acceleration/deceleration time, reduce load

motor over-load
Cause
Confirmation
Solution
Load is too heavy
Check actual load if the value of
parameter exceed maximum or not
Decrease load, adjust limit parameter
Oscillation of
machine
Check the machine if oscillation exists
or not
Modify the parameter of control loop;
enlarge acceleration/deceleration time
wiring error of
motor
Check wiring if error occurs or not, if
line breaks or not
Adjust wiring or replace encoder/motor
for a new one

Resistance discharge circuit over-load
Cause
Confirmation
Solution
Regenerative energy has
exceeded the capacity of
regenerative resistor .
Check the speed if it is too
high. Check the load if it is
too large or not.
lower motor rotational speed; decrease load
inertia ,increase external regenerative resistor,
improve the capacity of the driver and motor
Resistance discharge
circuit damage
/
Increase external regenerative resistor, replace
the driver with a new one
