: Not cleared

The droop pulses are not cleared.

The CLR/CLRN signal is input when a value other than "1" is set in Pr.419 , and the signal is input through terminal CR of the FR-A8AL when
Pr.419 = "1".

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.

The following shows the example of the clearing the value of the current position 2 monitor under the control mode other than the position
control mode.

Pulse monitoring on the operation panel
• 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.
• If -99999999 or 99999999 is exceeded on the pulse monitor, the monitor value is reset to 0.
NOTE
• The pulse count starts at servo on.
