Storage details
• The current value after combining
the main input and sub input
values from the main shaft is
stored.
• Value is stored even after Multiple
CPU system power supply OFF.
• The current value per cycle after
the main shaft gear is stored.
• One cycle is considered the cam
axis length per cycle.
• Value is stored even after Multiple
CPU system power supply OFF.
• The current value per cycle after
the auxiliary shaft gear is stored.
• One cycle is considered the cam
axis length per cycle.
• Value is stored even after Multiple
CPU system power supply OFF.
The current phase compensation
amount is stored.
• The current value per cycle is
stored, which is calculated from
the input travel value to the cam
axis. (The value after phase
compensation)
• Value is stored even after Multiple
CPU system power supply OFF.
• The current feed value as the cam
reference position is stored.
• Value is stored even after system's
power supply OFF.
• The current feed value while
controlling the cam axis is stored.
• Value is stored even after system's
power supply OFF.
The executing cam No. is stored.
The executing cam stroke amount is
stored.
The executing cam axis length per
cycle is stored.
The accumulative slippage of the
main shaft clutch smoothing with
slippage method is stored as a
signed value.
The accumulative slippage on the
auxiliary shaft clutch smoothing with
slippage method is stored as a
signed value.
