６．４．４ Explanation of Input/Output Signals
CAUTION：
・ To prevent malfunctions due to dispersion and chattering of input signals, please maintain input signals
at state of 20msec or more.
ａ） Input/output signals common to all modes
[Input Signal]
0：OFF（Level Input）、1：ON（Level Input）、0↓：Rise Input、1↑：Fall Input
any：Status（0、1、0↓、1↑)
Input 1〜4 Input 5 Input 6 Input 7
Universal Input
Return-to-
Origin
Emergency
Stop
Alarm Reset
Emergency Stop any Null 0 Null
Emergency Stop Cancellation any Null 1 Null
Return-to-Origin (0↓)※2 1↑※3 1 Null
Alarm Reset any Null 1 1↑
※1. Emergency stop command input signal is b-contact connection (negative logic).
※2. Valid only when origin has not been detected after turning on power.
If “1↑” signal is detected during origin detection, it will stop at that spot.
※3. Return-to-origin is rejected during a movement.
If “0↓” signal is detected during origin detection, it will stop at that spot.
[Output Signal]
0：OFF（Level Output）、1：ON（Level Output）
any：Status（0 、 1）
Output 1〜4 Output 5 Output 6 Output 7

Input Method of Signals
Level Input
OFF：0
ON ：1
Edge Input
Rise：1↑
Fall：0↓
The signal is maintained if ON (or OFF) input signal is detected and ON (or OFF)
condition continues. If OFF (or ON) signal is detected in the duration, this is
recognized as change in input.
Rise edge (or fall edge) of the input signal is detected.
Even if it goes OFF (or ON) in the duration, the input signal is self-maintained.
It will be recognized as change in input due to other input signals
