Probable cause
The power supply voltage fell
below the prescribed value.
The power supply capacity is
insufficient.
The UP-02 (applicable motor)
setting is wrong.
The resolver's wiring is dis-
connected or faulty.
There is poor contact at the
connectors.
An error occurred in the main
circuit.
The regenerative absorption
exceeded the internal absorp-
tion.
The power supply voltage is
outside the allowable range.
The Regeneration Resistor is
damaged.
An external Regeneration
Resistor is not being used and
the short bar has been
removed from between JP1
and JP2 on the terminal block.
The regeneration circuit is
damaged.
The Position Driver's internal
clock has stopped.
The mechanical system is
locked.
The power lines are wired
incorrectly.
The power lines are shorted-
circuited or grounded.
The UP-02 (applicable motor)
setting is wrong.
The mechanical system is
locked.
The power lines are wired
incorrectly.
The UP-02 (applicable motor)
setting is wrong.

Countermeasures
For 200-VAC input specifi-
cations, use a 170 to
264-VAC power supply.
For 100-VAC input specifi-
cations, use an 85 to
127-VAC power supply.
Increase the power supply
capacity.
Set the motor model code cor-
rectly.
Connect any places that are
disconnected.
Correct the wiring.
Make sure the connectors are
inserted firmly and locked into
place.
Replace the Driver.
Connect an external Regen-
eration Resistor.
Use a 170 to 264-VAC power
supply.
Replace the external
Regeneration Resistor.
If an external Regeneration
Resistor is not being used,
replace the Driver.
Mount a short bar between
JP1 and JP2.
Replace the Driver.
Replace the Driver.
Correct the places that are
locked.
Correct the wiring.
Correct the short-circuiting or
grounding.
Set the motor model code cor-
rectly.
Correct the places that are
locked.
Correct the wiring.
Set the motor model code cor-
rectly.
