• Also, setting "26 to 31" in Pr.52, Pr.774 to Pr.776, Pr.992 (multifunction monitor) changes the electronic gear operation
setting in the case of monitoring pulses. (Refer to

*1 The droop pulses are not cleared.
*2 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".
*3 Pulses are cleared when a clear signal is input. (The home position information is not retained.)
*4 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.
*5 The data is cleared when absolute position control is disabled.
*6 The home position return is not available.
NOTE
• The monitor value of the current position 2 is not cleared when switching between the first and second motors.
• For the details of the special register for the PLC function, refer to the PLC Function Programming Manual.
 Pulse monitoring on the operation panel (FR-DU08)
• The position command, current position and the status of droop pulses can be displayed on the operation panel.
• If displayed data has signs, minus signs appear for both upper and lower digits.
