Even when the power to the CNC is turned off, a battery–powered pulse
coder stores the current position. No reference position return is required
when the power to the CNC is restored.
[Classification] Output signal
[Function] Notifies that the life of the absolute position detector battery, which is
used to keep the machine position even when the CNC power is off, is
about to expire.
Generally, this signal is used to turn on a lamp for calling the operator’s
attention.
[Operation] The signal becomes 1 when:
· The battery voltage for the absolute position detector becomes lower
than or equal to the rating.
The battery need be replaced in the immediate future.
The signal becomes 0 when:
· The battery voltage for the absolute position detector is higher than or
equal to the rating.
[Classification] Output signal
[Function] Notifies that the life of the absolute position detector battery, which is
used to keep the machine position even when the CNC power is off, has
expired.
[Operation] The signal becomes 1 when:
· The battery voltage for the absolute position detector becomes 0 V.
The battery need be replaced before the CNC power is turned off.
The signal becomes 0 when:
· The battery voltage for the absolute position detector is higher than or
equal to 0 V.
