SD715 Low speed Motion
operation cycle
Low speed Motion operation
cycle
The time taken for low speed Motion operation cycle is stored in [s]
units.
0 to 65535[s]
S (Low speed
operation cycle)
SD716 Low speed Motion
maximum operation
cycle
Low speed Motion maximum
operation cycle
• The maximum time taken for low speed Motion operation cycle is
stored in [s] units.
0 to 65535[s]
• When "0" is written, the maximum value is reset.
SD717 Operation cycle
counter
Operation cycle counter • Incremented by 1 each time the Motion operation cycle is executed,
and when 65535 is exceeded the count returns to 0 and starts again.
0 to 65535
• When low speed Motion operation cycle is enabled, the count returns
to 1 and starts again if the low speed operation cycle magnification
setting is exceeded. (The low speed Motion operation cycle is
executed when this counter is 1.)
