High voltage of power
grid
Check the fluctuation of power
grid, 220V driver normal voltage
range 200V ~ 240V, 380V driver
normal voltage range 360V ~
420V. If the voltage fluctuation is
large, it is recommended to use
the correct voltage source and
regulator.
Excessive load

(insufficient
regeneration capacity)
(1) connect external regenerative
resistor, (220V: bus voltage
U0-05 = 380 discharge starts,
U-05 = 350 discharge ends;
380V: U-05 = 700 discharge
starts, U-05 = 660 discharge
ends;)
(2) Increasing Acceleration and
Deceleration Time
(3) Reducing load inertia
(4) Reduce start-stop frequency
(5) Replacement of larger power
drivers and motors
Brake resistance
damage or excessive
resistance value
Check the regenerative resistor
and replace the external resistor
with the appropriate resistance
value. See chapter 1.4.1 for the
selection of the external resistor.

Sampling Circuit
The AC gear of the multimeter
measures the input value of the
servo LN (R/S/T), which is 220V
± 10% of the normal value. If the
power supply voltage is more
than 220V+10% (380V+10%),
