 Pulse received by Lo-08 is not same
as the one sent by PC/PLC..
1. Check whether servo grounding is
reliable.
2. Check whether signal cable is
There is position twisted-pair shield cable, whether
error. shielding layer is connected to
housing correctly.
 Check whether motor shaft coupler is
locked tightly.
 Check whether device has vibration.
Adjust the gain according to chapter 9.
Possible Cause
Output short-circuit or module malfunction
Main circuit DC voltage is too high.
Main circuit DC voltage is too low
Hardware failure inside drive
Motor cable sequence error
High current is output for long time.
Speed is too high
High current is output for long time.
Position loop trace error overflow
Servo motor encoder is damaged.
External emergency stop terminal is valid
Temperature of servo drive radiator is too
high
In the state of power supply connection of
main circuit, the voltage of one phase in
three-phase power supply is too low.
Brake parameters aren't set correct or
continuous brake time is too long.
