(4) There is a significant differ-
ence between the rated capacity
of the inverter and the capacity of
the connected motor.
Check if the capacity of the con-
nected motor is at least 3 ranks
lower or at least 2 ranks higher
than the rated capacity of the in-
verter.
→ Review the capacity of the in-
verter
.
→ Manually set 1st Motor
Parameter Io (3007-07 hex), 1st
Motor Parameter R1 (3007-08
hex), and 1st Motor Parameter
L (3007-09 hex).
→ Do not use the auto-tuning
and auto torque boost functions.
(Set 1st Torque Boost
Selection (301F-0D hex) and
2nd Torque Boost Selection
(301F-0E hex) to 0.)
Use a motor that is suitable for
the inverter.
(5) The motor is a high-speed
motor or other special motor.
Do not use the auto-tuning and
auto torque boost functions. (Set
1st Torque Boost Selection
(301F-0D hex) and 2nd T
orque
Boost Selection (301F-0E hex)
to 0.)
To use a special motor, in addi-
tion to auto-tuning, consider set-
ting the motor constants manual-
ly.
(6) Tuning operation (Parameter
3007-05 hex = 2) was performed
to rotate the motor while the
brake is applied to the motor.
Use the turning method that does
not cause the motor to rotate
(
1st Auto tuning (3007-05 hex)
= 1).
Use the tuning method without
applying the brake (1st Auto
tuning (3007-05 hex) = 2).
Check the brake condition before
performing auto-tuning.
