1.5.2 Absolute Position Detection
Overview
Even after the CNC is turned off, the pulse coder, which is backed up
by a battery, retains the position. This eliminates the need to perform a
reference position return when the CNC is turned on.
Signal
Absolute position detector battery low voltage alarm signal PBATL <F040#6>
[Classification] Output signal
[Function] Notifies the user that the battery for the absolute position detector is
running down.
[Operation] The signal is set to "1" if:
- The voltage of the battery for the absolute position detector falls
below a preset level. The battery must be replaced as soon as
possible.
The signal is set to "0" if:
- The voltage of the battery for the absolute position detector is
equal to or greater than the rated value.
Absolute position detector battery zero voltage alarm signal PBATZ <F040#5>
[Classification] Output signal
[Function] Notifies the user that the battery for the absolute position detector,
which retains the machine position even after the CNC is turned off,
has run down.
[Operation] The signal is set to "1" if:
- The voltage of the battery for the absolute position detector is
equal to 0V. The battery must be replaced before the CNC can be
turned off.
The signal is set to "0" if:
- The voltage of the battery for the absolute position detector is
equal to or greater than 0V.
