Fault Principle
Phase loss on the output side
Fault Cause
Solution
Motor fault
Check whether the cables between the servo drive and the motor are
short-circuited or in poor contact.
Disconnect the servo drive from the motor, measure the inter-phase
resistance of U, V, W phases of the motor by using the M mode in the ohm
function of the motor, and check whether the resistance is the same and
above 5 M
Ω
. If yes, connect the servo drive and the motor and perform trial
running again.

Ground
Module fault
Power off the servo drive, and measure the IGBT by using the diode
function of the multimeter. Connect the red probe to the - terminal, and
measure R, S, T in turn by using the black probe. Then, connect the black
probe to the + terminal, and measure R, S, T in turn by using the red probe.
If the six measurement values are all about 0.3 V, it indicates that the IGBT
is normal.
Internal component
fault
If the fault persists after you perform the preceding operations, contact the
IMM manufacturer.
Fault Code
ERR14
Fault Principle
Module overheat
Fault Cause
Solution
Cooling fan problem
Check whether the fan is damaged. Measure the power supplied by the
drive board to the fan, and see whether the measured value is 24 V.
Eliminate the related problems and perform trial running again.
Air filter problem
Check whether the air filter is blocked. If yes, clean the air filter.
Too high ambient
temperature
If the temperature inside the cabinet exceeds 50
C, enhance ventilation and
heat dissipation of the cabinet.
