Reports Reason
Over-voltage 0x5000 Voltage of the power supply is too high, or the servo
drive failed to absorb kinetic energy while braking a
load. A shunt resistor may be required. The over-voltage
threshold differs with the power stage model (refer to
product user manual). A probable reason for this
protection is an attempt to decelerate a motor that is
moving so fast that the drive fails to absorb the motor’s
kinetic energy. The solution to this is to decelerate more
slowly or to add a shunt resistor to the power supply.
Under-voltage 0x3000 The power supply has been shut down or its impedance
is too high. The under-voltage threshold differs with
power stage models; refer to the product user manual. A
probable reason is that PL[1] and CL[1] have been set too
high for the power supply.
Short circuit 0xb000 A large, fast current pulse has been detected. The motor
or its wiring may be defective or the drive may be faulty.
Over-temperature 0xd000 The power stage of the drive is too hot. An additional
heatsink or forced cooling is required.
Over-current 0x8 An unexpected, large current has exceeded 1.15 * MC.
The current loop or the winding shape function HV[N]
may need better tuning.
