Tab. 5-64:
Accumulated value of estimated feedback pulses when PM sensorless vector control is used
● When Pr. 419 = "10", the current position information is retained, thus the pulse monitor is not
cleared at servo-OFF (LX-OFF).
● The monitor value of the current position 2 is cleared when the home position return is completed
during position control.
● Pulses are cleared according to the following conditions:
Clearing condition
Servo-OFF (LX-OFF)
(output shutoff )
Clear signal input
Home position return
completed
: cleared, x: not cleared
Tab. 5-65:
The CLR/CLRN signal is input when Pr. 419 = "0, 2, or 10", and the signal is input through terminal
CR of the FR-A8AL when Pr. 419 = "1".
The droop pulses are not cleared.
Pulses are cleared when a CLEAR signal is input. (The home position information is not retained.)
Pulses are cleared only when the home position return is completed. Once the pulses are cleared,
they are not cleared even if the LX signal is turned ON.
The data is cleared when absolute position control is disabled.
The home position return is not available.
