4. SYSTEM STARTUP
(4) When selecting dual port memory
When 4 (dual port memory input) is selected as the sensor destination,
side limit switch input signal
(LSPC),
side limit switch input signal (LSNC) and proximity dog input signal (DOGC) are imported as
substitutes for sensors.

POINT
• When the sensor input command (LSPC, LSNC, DOGC) is turned on, a
normally-open contact turns on (a normally-closed contact turns off). The
polarity of the limit switch input command is the normally closed contact. The
polarity of the proximity dog input command can be changed by proximity dog
input polarity (parameter No.0240).
CAUTION
• When "1: driver input" and "2: digital input" are selected as sensor destinations, a delay occurs due
to the communication to detect the signal status. Take the delay time due to communication into
consideration when installing each sensor.
• Communication delay when control cycle is 0.88ms: approx. 2ms
• Communication delay when control cycle is 0.44ms: approx. 1.5ms
• Communication delay when control cycle is 0.22ms: approx. 1.3ms
