Shut down the device with
interference
Alarm at the moment
of high-speed
stop/start
Increase the acceleration time
Over speed(actual
speed ≥
P3-21/P3-22)
1. check if there is external force
make the motor over speed
2. input command frequency too
high
3. electronic gear ratio too large
Drive P0-33 must match the motor
code on the motor label
U, V, W wiring error
with ground
1. Check encoder cable or change
it 2. Set servo to bb state, monitor
U0-10, rotate motor shaft by hand,
U0-10 increase at one direction
and decrease at another direction
(0~9999)
Check P3-21/P3-22
max speed limit
When actual speed larger than
P3-21/P3-22, it will alarm
Analog Tref zero
calibration over
limit
Analog zero
calibration operation
error
Please not add analog value when
calibrating
Analog Vref zero
calibration over
limit
Analog zero
calibration operation
error
Please not add analog value when
calibrating
Position offset too
large
The difference
between setting
position and actual
position is over the
limit
1. check whether the motor stall,
decrease the position setting speed
2. increase the offset pulse limit
P0-23
Drive P0-33 must match the motor
code on the motor label
Short circuit with
drive UVW or motor
problem
1. measure the phase resistor of
motor phase UVW, if not
balanced, change the motor 2. If
short circuit between UVW and
PE, change the motor 3. Measure
UVW output with multimeter
(diode gear), black pen test P+,
red pen test UVW, red pen test P-,
black pen test UVW. 6. Group
voltage any one is 0, change the
drive
Run the motor without load to
check the problem
