CN1 Control Input Signal Connection Diagram
Note (1) If the limit input signal inputs (Servo Drive's forward drive prohibited sig-
nal and reverse drive prohibited signal) are not allocated, the Servo Drive
will not stop the Servomotor when the signal is input, and the Position
Control Unit will also not detect limit inputs as errors. When using a Posi-
tion Control Unit, always allocate the Servo Drive's forward drive prohib-
ited signal and reverse drive prohibited signal to enable use of the limit
input signals. (Refer to
6-4 Standard Settings for Servo Drives Using
MECHATROLINK .)
(2) The signal width of the limit input signals (forward drive prohibited signal
and reverse drive prohibited signal) and origin proximity input signal (ori-
gin return deceleration limit switch) must be longer than the MECHA-
TROLINK communications cycle. If the input signal width is shorter than
the communications cycle, the Position Control Unit will be unable to de-
tect the input signal.
(3) When selecting a sensor for the origin proximity input signal (origin return
deceleration LS), use a sensor such as a Photoelectric Sensor, which
does not have chattering, because the origin signal is detected after the
input goes from ON to OFF during the origin search. If a switch with con-
tacts is used, the origin position may shift due to the switch contact's chat-
tering.
