 Setting for the PM sensorless vector control by selecting PM parameter
initialization on the operation panel ("PM")
• The parameters required to drive a PM motor (MM-GKR or EM-A) are automatically set by batch. (Refer to
• The PM LED on the operation panel turns ON when the PM sensorless vector control is set.
The following shows the procedure to initialize the parameter settings for an MM-GKR motor by selecting PM parameter
initialization on the operation panel.
Operating procedure
1.
Turning ON the power of the inverter
The operation panel is in the monitor mode.
2.
Changing the operation mode
Press the PU/EXT key to choose the PU operation mode.
The PU LED turns ON.
3.
Selecting the parameter setting mode
Press the MODE key to choose the parameter setting mode.
The PRM LED is ON.
4.
PM parameter initialization
Turn the setting dial or press the UP/DOWN key until "PM" (PM parameter initialization) appears.
5.
Displaying the set value
Press the SET key to read the present set value.
The value set in Pr.998 is displayed.
6.
Changing the setting value
Turn the setting dial or press the UP/DOWN key to change the value to "3024", and the SET key to confirm it.
"3024" and "PM" are displayed alternately. The setting is completed.
Setting
0 (initial value) Parameter setting (in frequencies) for an induction motor
3024 Parameter setting (in rotations per minute) for an MM-GKR motor
3044 Parameter setting (in rotations per minute) for an EM-A motor
NOTE
• If the motor parameter initialization is performed by using PM parameter initialization for the use of a PM motor, the setting of
Pr.998 PM parameter initialization is also changed automatically.
• In the initial parameter setting, the capacity same as the inverter capacity is set in Pr.80 Motor capacity. To use a motor
capacity that is one rank lower than the inverter capacity, set Pr.80 before performing PM parameter initialization.
• Use Pr.998 to set a speed by adjusting frequencies or to monitor it, or to drive a PM motor other than the MM-GKR or EM-A.
