380V: U0-05=700 start
discharging, U0-05=660 discharge
end)
2. increase
acceleration/deceleration time
3. decrease load inertia
4. decrease start/stop frequency
5. change larger power drive and
motor
regenerative resistor
broken or value too
big
Change suitable resistor, refer to
chapter 3-4
Run the motor without load to
check the problem
Bus
undervoltage(220
V: U0-05≤140.
380V: U0-05 ≤
300)
Power grid voltage too
low
1. Check the power grid, 220V
servo drive voltage range
200~240V, please use regulator.
2. change large capacity
transformer
Repower on after voltage is stable
Bus voltage
charging failure
Please note if there is relay
ON/OFF sound when drive power
on
Module
temperature too
high
1. long time running
with large load
2. environment
temperature too high
3. short circuit
between UVW
1. consider change the motor
capacity(mointor U0-02, motor
present torque) decrease the load
2. good ventilation, check if the
fan is running when module
temperature U0-06≥45℃
3. check the UVW wiring
Motor temperature
too high
1. long time running
with large load
2. environment
temperature too high
Environment
temperature is too low
The environment must up to 0℃
Drive P0-33 must match the motor
code on the motor label
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)
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
