(5) Wiring to the motor is incor-
rect.
Check the wiring to the motor.
→ Wire the inverter output wires
(U, V, and W) to the motor wires
(U, V
, and W), respectively.
Wire the output wiring of the in-
verter (U, V, and W).
(6) The speed does not increase
in torque limiting operation.
Check the values of Torque
Limit 1 (Four-quadrant Mode
Forward Power Running)
(3004-29 hex), T
orque Limit 2
(Four-quadrant Mode Reverse
Regeneration) (3004-2A hex),
Torque Limit 3 (Four-quadrant
Mode Reverse Power Running)
(3005-11 hex), and Torque Limit
4 (Four-quadrant Mode
Forward Regeneration)
(3005-12 hex).
→ Change the torque limit pa-
rameters to appropriate values.
Or, if torque limit operation is not
required, change it to Disable
(300%).
Set the torque limit appropriately.
(7) Wiring between the pulse
generator and the option card is
incorrect.
One of the wires is faulty be-
tween the pulse generator (PG)
and the pulse input terminals.
→Check and correct the wiring.
