IPM motor control <IPM>
[IPM motor specification list]
(3) IPM motor control dedicated parameter
The following parameters are activated only under IPM motor control.
See the reference pages for details.
4.3.3 IPM motor test operation (Pr.800)
<IPM>
The above parameters can be set when Pr.160 User group read selection = "0." (Refer to page 201)
(1) Test operation
· To activate the IPM motor test operation, set
Pr.998 IPM parameter initialization
, change the control to IPM motor control,
then set
Pr.800 Control method selection
= "9."
Perform a test operation by giving a frequency and a start command under each of PU/External/Network operation mode.
· P.RUN on the operation panel (FR-DU07) flickers during the IPM motor test operation.

Speed control P gain 1
The proportional gain during speed control is set. (Setting this
parameter higher improves the trackability for speed command
changes. It also reduces the speed fluctuation due to a load fluctuation.)
84
821
Speed control integral time 1
The integral time during speed control is set. (Setting this parameter
shortens the return time to the original speed when the speed fluctuates
due to a load fluctuation. )

Without connecting an IPM motor, the frequency movement can be checked by the monitor or analog signal output.
Two types of operation can be selected using this parameter: an actual operation by connecting an IPM
motor, or a test operation without connecting an IPM motor to simulate a virtual operation.
