IPM motor control <IPM>
4
PARAMETERS
(1) IPM motor control setting by selecting the parameter setting mode on the operation panel
()
(2) IPM motor control display and IPM motor control signal
P.RUN on the operation panel (FR-DU07) is lit and the IPM motor control signal (IPM) is output during IPM motor control.
For the terminal to output the IPM motor control signal, assign the function by setting "57 (positive logic)" or "157
(negative logic)" to any of Pr.190 to Pr.196 (Output terminal function selection).
POINT
· The parameters required to drive an IPM motor are automatically changed as a batch. (Refer to page 80.)
Operation example
Initialize the parameter setting for a premium high-efficiency IPM motor (MM-EFS) by selecting the parameter
setting mode on the operation panel.
Setting Description
0 Parameter settings for a general-purpose motor
1 Parameter settings for a high-efficiency IPM motor MM-EF (rotations per minute)
12 Parameter settings for a premium high-efficiency IPM motor MM-EFS (rotations per minute)
REMARKS
· Performing IPM parameter initialization by selecting the parameter setting mode on the operation panel automatically changes
the Pr. 998 IPM parameter initialization setting.
· The parameter initialization sets the same capacity as the inverter capacity to
Pr. 80 Motor capacity
. To use a 0.4kW MM-EF, set
Pr. 80
Motor capacity
= "0.4" before performing IPM parameter initialization by selecting the parameter setting mode on the operation panel.
· The IPM parameter setting is displayed as "1, 12" in the parameter setting mode even if
Pr.998 IPM parameter initialization
= "101, 112."
