PARAMETERS
PM sensorless vector control
4.3.3 Changing the control method (Pr.800)
The above parameter can be set when Pr.160 Extended function display selection ="0". (Refer to page 182)
When an S-PM geared motor is used (Pr.998="6004 or 6104"), the operation is performed under speed control.
(1) PM motor test operation (Pr.800 ="9")
Without connecting a PM motor, the speed 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 a PM motor, or a test
operation without connecting a PM motor to simulate a virtual operation.
Setting Pr.800 Control method selection = "9" will enable the PM motor test operation in speed control.
Perform a test run by giving a speed command and a start command under each of PU/External/Network operation mode.
CAUTION
According to the motor to be connected, perform PM parameter initialization. Incorrect initial setting of
parameters may damage the motor.
In the initial setting, FR-E720EX-0.1K to 0.75K is set for an MM-GKR motor, and FR-E720EX-1.5K to 3.7K is set
for an S-PM geared motor.
Only use a motor that is a dedicated PM motor (MM-GKR motor or S-PM geared motor).
Select the control method between speed control and position control.
Under speed control, the motor is controlled so that its rotation speed (estimated speed) and the speed command match.
Under position control, a speed command is calculated to eliminate the difference between position command and estimated
position and output to rotate the motor.

REMARKS
In the test operation, current is not detected and voltage is not output. Related monitor displays of the output current and
voltage show "0".
