10.2 Alarm Causes & Troubleshooting
There is no motor type set in servo
driver
Set the motor type in d4.01.
Please contact manufacturer
The ABZ signal cable is
disconnected.
The UVW signal cable is
disconnected.
Interferences are suppressed.
Encoder cable problem
Check encoder cable.
Remove interference(Such as
connect the motor cable to SHIELD
terminal etc.)
ABZ and UVW signals of the
encoders incur error
simultaneously.
The driver temperature exceeds
83°C.
Check whether the selected driver
has enough power.
The bus voltage of the driver
exceeds the allowable range.
Check the input voltage,or
determine whether a braking
resistor is connected.
The voltage of the driver bus is
below the allowable range.
Check the input power.
Power on AC first,then power DC.
Reduce deceleration.
The power tube in the driver is
faulty, or short circuit occurs on the
phase line of the motor.
Check motor wires. If the motor
works properly, it can be judged that
faults occur on the power tube in
the driver.
The actual power of brake resistor
is larger than rated power
Control loop parameters setting
problem.
Overload or block.
Encoder signal problem.
Set VFF (d2.08) as 100%,increase
kpp(d2.07) and kvp(d2.01).
Choose bigger power motor or check
whether the load is blocked.
Check the encoder cable.
The logic voltage is lower than 18V.
Check the logic power supply 24V.
Control loop parameters setting
problem.
Overload or block.
Increase kvp(d2.01).
Choose bigger power motor or check
whether the load is blocked.
The input pulse frequency exceeds
the allowable maximum value.
Check the input pulse frequency and
the maximum permissible value of
the frequency.(d3.38)。
Check the wiring according to
