(b) Setting Motor Constants
CAUTION
S Be sure to set the motor constants before the initial operation and after replacement of the
motor. Reconfirm the motor constants after they have been set.
Failure to observe this caution may result in motor malfunctions such as sudden acceleration.
S In the following cases when under flux vector control, be sure to adjust the PG zero-pulse
as described in 4.3 (3) (e) PG Zero-pulse Adjustment:
• Before initial operation.
• After replacing the motor.
• After replacing the PG.
Set the motor constants in accordance with the values listed on the motor nameplate.
If the open loop vector control is selected, set
the motor constants in the order shown in
Table 11.
If the flux vector control is selected, set the
motor constants in the order shown in Table
12.
If the setting of the motor capacity selection
(E1-02) is changed, the motor constants will
return to their initial values.

the value in the lower row.
E1-05 Number of motor poles (POLES) If (POLES) is not shown on the nameplate, set E1-05 to 6.
E1-06 Motor max. speed (r/min) or (min -1 ) If two values are shown for (r/min) or (min -1 ), set E1-06 to the
value in the upper row.
E1-07 Motor base speed (r/min) or (min -1 ) If two values are shown for (r/min) or (min -1 ), set E1-07 to the
value in the lower row.
E1-08 Motor min. speed 10% of the base
speed or higher Initial setting: 10% of base speed.
