1.1 Setting procedure of PM sensorless vector control
* Two IPM parameter initialization methods are available for MM-CF IPM motors; setting Pr.998 IPM parameter initialization, and selecting
(IPM parameter initialization) mode on the operation panel. One of the two methods can be selected.
To change to the PM sensorless vector control, perform IPM parameter initialization at first. If parameter initialization is performed after
setting other parameters, some of those parameters will be initialized too. (Refer to page 6 for the parameters that are initialized.)
· This inverter is set for a general-purpose motor in the initial setting. Follow the following procedure to change the
setting for the PM sensorless vector control.
REMARKS
· To use a motor capacity that is one rank lower than the inverter capacity, set Pr. 80 Motor capacity before performing
IPM parameter initialization.
Test run
Perform IPM parameter initialization by selecting IPM in the parameter setting mode on the operation
panel.* (Refer to page 3)
Set the operation command. (Refer to the Instruction Manual.)
Set "3003" (MM-CF IPM motor parameter setting (rotations per minute)) in (IPM parameter
initialization) to select the PM sensorless vector control.
P.RUN on the operation panel (FR-DU07) is lit when PM sensorless vector control is set.
Select the start command and speed command.
Set parameters such as the acceleration/deceleration time and multi-speed setting.
Set parameters such as the acceleration/deceleration time and multi-speed setting
as required.
Perform offline auto tuning for an IPM motor. (Pr.96) (Refer to page 7)
Use Pr.998 to perform IPM parameter initialization. (Refer to page 4)
Setting "8009" or "8109" in Pr. 998 IPM parameter initialization selects the IPM
motor parameter settings.
"8009":
Parameter (rotations per minute) settings for an IPM motor other than MM-CF
"8109": Parameter (frequency) settings for an IPM motor other than MM-CF
To perform tuning, set "1" (offline auto tuning without rotating motor (for other
than MM-CF)) in Pr. 96.
Set the motor. (Pr.9, Pr.71, Pr.80, Pr.81, Pr.83, Pr.84) (Refer to page 7)
Set "8093 (IPM motor other than MM-CF)" in Pr.71 Applied motor. Set Pr.9
Electronic thermal O/L relay, Pr.80 Motor capacity, Pr.81 Number of motor poles,
Pr.83 Rated motor voltage, and Pr.84 Rated motor frequency according to the
motor specifications.
(Setting "9999 (initial value)" in Pr. 80 or Pr. 81 selects V/F control.)
Driving an IPM motor other than MM-CF
Driving an MM-CF IPM motor
As required for MM-CF.
· Perform offline auto tuning for an IPM motor. (Refer to page 7)
