Speed Control Under Pm Motor Control; Setting Procedure Of Pm Motor Control - Mitsubishi Electric FR-F800 Instruction Manual

5.3

Speed control under PM motor control

Purpose
To adjust the gain during PM
motor control
To stabilize torque feedback
signal
Speed control performs control so that the speed command and the actual motor rotation speed match.
5.3.1

Setting procedure of PM motor control

This inverter is set for a general-purpose motor in the initial setting. Follow the following procedure to change the
setting for the PM motor control.
Driving an MM-EFS or MM-THE4 IPM motor
Perform IPM parameter initialization. (Refer to
Set "12 or 112" in Pr.998 PM parameter initialization, or select "12" in
Setting value "12": parameter settings for MM-EFS/MM-THE4 IPM motor (rotations per minute)
Setting value "112": parameter settings for MM-EFS/MM-THE4 IPM motor (frequencies)
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.
Set the operation command. (Refer to
Select the start command and speed command.

Driving a PM motor other than MM-EFS/MM-THE4
Set the motor. (Pr.9, Pr.71, Pr.80, Pr.81, Pr.83, Pr.84) (Refer to
Set "8093 (IPM motor other than MM-EFS/MM-THE4)" or "9093 (SPM motor)" in Pr.71
Applied motor. Set Pr.9 Rated motor current, 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.)
Perform offline auto tuning for a PM motor. (Pr.96) (Refer to
Set "1" (offline auto tuning without rotating motor (for other than MM-EFS/MM-THE4))
in Pr.96,
Configure the initial setting for the PM motor control using Pr.998. (Refer to
150.)
When the setting for the PM motor is selected in Pr.998 PM parameter initialization,
the PM motor control is selected.
[PM] on the operation panel (FR-DU08) is lit when the PM motor control is set.
"8009": Parameter (rotations per minute) settings for an IPM motor other than MM-
EFS/MM-THE4
"8109": Parameter (frequency) settings for an IPM motor other than MM-EFS/MM-
THE4
"9009": Parameter (rotations per minute) settings for an SPM motor
"9109": Parameter (frequency) settings for an SPM motor
page 200.)
As required for MM-EFS/MM-THE4
• Perform offline auto tuning for a PM motor. (Refer to
