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 in
servo BB state, monitor U0-05, the
voltage measured by the multimeter
* 1.414 < U0-05 (within 10V error),
then the servo driver is faulty and
needs to be sent back for repair.

Disconnect the power supply of the
driver, check the connection of the
encoder cable, if there is cable
loosening, it is recommended to use
the multimeter to test the
conduction condition; after
eliminating errors, power on again
Hot plugging is strictly prohibited,
