EXTERNAL INPUT TIME
Records the amount of time the external input signal is on.
These timers can be preset so when the COUNT data exceeds the SET value, a C level
alarm will show up on the CRT.
NC WORK COUNTER
Pressing the PAGE key will display this screen (when at NC Hour Meter parameter
screen). These counters increment whenever an M02 or M30 are executed. During
Machine Lock mode, these counters do not increment.
SPINDLE CONTROL PARAMETER
These parameters are servo constants and other related data that are set at the factory.
These parameters should not be changed unless requested by Okuma.
On machining centers, the backup counter is not shown. Data can be backed up immediately by
pressing the “extend key” (F8) then the “backup” key (F7). It is recommended that this proce-
dure be done every time a parameter is changed.
Incidentally on Okuma Grinders, the backup occurs as soon as the WRITE key is pressed.
