Check the regenerative resistor and
replace the external resistor with the
appropriate resistance value. See

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%), check the
power supply voltage; if the power
supply voltage is normal, then the
servo BB state, monitor U0-05, the

* 1.414 < U0-05 (within 10V error),
then the servo driver is faulty and
needs to be sent back for repair.
