Position control
(3) Travel completed signal (MEND signal)
The travel completed signal (MEND signal) is turned ON when the in-position signal (Y36) is ON and the position
command creating signal (PBSY) is OFF. For the travel completed signal (MEND signal), assign the function by setting
"38 (positive logic) or 138 (negative logic)" in any of Pr.190 to Pr.192 (output terminal function selection).
(4) Rough match signal (Pr.507, CPO signal)
The rough match signal is turned ON when the remaining command distance [before the electronic gear] (= target position
[before the electronic gear] - current position [before the electronic gear]) falls below the setting of
Pr.507 Rough match
output range
. For the rough match signal (CPO signal), assign the function by setting "55 (positive logic) or 155 (negative
logic)" in any of
Pr.190 to Pr.192 (output terminal function selection)
.
(5) Position detected signal (Pr.506, Pr.510, Pr.511, Pr.536, FP signal)
The position detected signal (FP signal) is turned ON when the current position [before the electronic gear] exceeds the
position detection (
Pr.510
+
Pr.511
). For the position detected signal (FP signal), assign the function by setting "60
(positive logic) or 160 (negative logic)" in any of
Pr.190 to Pr.192 (output terminal function selection)
.
Whether the position detection is determined at a plus position or minus position can be selected by Pr.536 Position
detection selection. When "0" is set, the position is detected on both the plus and minus sides. When "1" is set, the position
is detected on the plus side only. When "2" is set, the position is detected on the minus side only.
When a current position varies, the position detected signal may repeat ON/OFF (chatter). Setting hysteresis to the
detected position prevents chattering of the signal. Use Pr.506 Position detection hysteresis width to set a hysteresis width.
