The difference between the
current position of the twin
axis has reached the twist
detection value.
(The difference between the

Error occurred in slave axis.
(Error occurred in slave axis.)
Please confirm the situation of the
error occurred and error content of
slave axis.
1587
Power supply may have
been stopped momentarily
due to power failure.
(Instantaneous power failure
occurred due to power
voltage of servo amplifier)
Check the voltage of the power
supply in the plant. Turn the
machine power back ON and start
production. If the error persists,
contact PFSC.
1588
Regenerative resistor cable
may be disconnected.
(Power voltage inside the
servo amplifier is beyond the
specified range.)
Check the cable connected to the
regenerative resistor. If the error
persists, contact PFSC.

Cause Inspection and Solution
Power supply may have
been stopped momentarily
due to power failure.
(Instantaneous power failure
occurred due to power
voltage of servo amplifier)
Check the voltage of the power
supply in the plant. Turn the
machine power back ON and start
production. If the error persists,
contact PFSC.
1590
Ground fault in the cable
between the motor and servo
amplifier. Motor or servo
amplifier may be at fault.
(Current supplied to the
motor is beyond the specified
value.)
Check the situation of the error
occurred and error message, and
contact PFSC.
1591
Internal fan may be stopped.
(Temperature inside the
servo amplifier is beyond the
specified value.)
Check the condition of the fan. Make
sure that there is no obstacle around
the cooling fan.

1) Broken motor cable
2) Collision with some
objects causes the machine
to slow down suddenly.
Machine may have been
deformed.
(Output of the servo amplifier
is beyond the specified
value.)
Make sure there is no axis
interference and no foreign objects
get caught. After turning OFF the
machine power, if the error persists,
contact PFSC.

Cause Inspection and Solution
Servo amplifier is at fault or
at high load during operation.
Power to the machine may
be beyond the specified
value.
(Regenerative load of the
servo amplifier is beyond the
specified value.)
Check the voltage of the power
supply in the plant. After turning
OFF the machine power, if the error
persists, contact PFSC.
1594
Encoder cable may be
broken; Servo amplifier or
encoder may be at fault.
(Encoder-servo amplifier
communication broke^ and
the wire break detection
function was triggered.)
Check the encoder wiring and the
wiring between motor and driver. If
the error persists, contact PFSC.
1595
Encoder cable may be
broken; Servo amplifier or
encoder may be at fault.
(Encoder-servo amplifier
communication broke^ and
the wire break detection
function was triggered.)
Check the encoder wiring and the
wiring between motor and driver. If
the error persists, contact PFSC.
1596
Servo amplifier or motor may
be at fault.
(Motor cannot follow the
command.)
After turning OFF the machine
power, if the error persists, contact
PFSC.
