(2) When following to command (Pr7.40-bit0=1)
During magnetic pole position estimation, even if servo is on (motor is in activated state), turn Servo_Active
bit of RTEX status to 0.
After completion of magnetic pole position estimation, Servo_Active bit of RTEX status is turned to 1.
Example: Movement during CP control, Pr7.43=7
1 After control power is turned on, if turning servo on (make Servo_On bit 1), motor is activated while
Servo_Active bit remains to be 0 and magnetic pole position estimation is implemented.
2. During magnetic pole position estimation, magnetic pole detection completion output
(SI-MON4/EX-SON bit) and Servo_Active bit are turned to be 0. During this, set command position of
upper device to value of actual position (APOS) and make command position follow actual position
(APOS).
When magnetic pole position estimation is completed normally, magnetic pole detection completion
output (SI-MON4/EX-SON bit) and Servo_Active bit are turned to be 1.
*1) Be careful that the motor power is supplied but the Servo Active bit is zero while estimating pole position.
