Any two phases of
motor are
short-circuited
Measure whether the three-phase resistance of motor is
balanced with a multimeter (for 5.0NM motor, it is about 30
Ω). In case of three-phase imbalance or large difference of
resistance value, the motor is damaged.
Input voltage is too high
Check the input power voltage
Encoder loop of
controller is abnormal
Encoder cable is
disconnected or
short-circuited
Rearrange the encoder cable
Encoder hardware is
damaged
Resistance during
open/close process
Check for the foreign matter or mechanical jam or too large
door width
Phase loss of motor
during the operation of
door operator
Check the motor power line
Rearrange the encoder cable
Any one phase of motor
is short to ground
Measure the resistance between the motor three-phase and
ground which should be infinite.
Measure the input voltage which should be 220V ± 20%
