Speed Control Under Pm Motor Control - Mitsubishi Electric FR-F820-00046 Instruction Manual

5.3

Speed control under PM motor control

Purpose
To adjust the gain for 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
PM PM PM
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 the IPM motor MM-EFS or MM-THE4 (standard structure models)
Operating procedure
1.
Performing the motor parameter initialization (Refer to
Set "12, 14, 112, or 114" in Pr.998 PM parameter initialization, or select "
14" on the operation panel.
Setting
12
112

114
2.
Parameter setting (acceleration/deceleration time, multi-speed setting, etc.)
Set parameters such as the acceleration/deceleration time and multi-speed setting as required.
3.
Operation command setting (Refer to
Select the start command and speed command.
4.
Perform the test operation.
When using the MM-EFS or MM-THE4, perform offline auto tuning for a PM motor as required. (Refer to
