6-2 Example of operation by origin detection method
(1) Stop by origin signal after origin proximity detection (value of parameter 1 address A+0003
set to "00")
With this mode, the origin proximity signal and origin signal are captured from the external input
connector and zero return is performed.
When origin signal input is input by an open collector output signal, connect the signal to the sensor
input (pins 10 and 22) for the origin. The response time is 1 ms or less. (a or b contacts can be
switched in parameters.)
When the differential driver output signal is input, connect the signal to the sensor input (pins 13-38,
25-50) for the origin. The response time is 250 kpps (0.04 ms) or less. (a or b contacts can be
switched in parameters.)
In this mode, operation is started at high-speed zero return as shown below, and deceleration
operation is performed at the edge of the origin proximity signal. After the low-speed zero return
speed is reached after escape from origin proximity, operation is stopped immediately by the initial
origin signal to confirm the origin.
(2) Origin count method 1 (value of parameter 1 address A+0003 set to "01")
With this mode, the origin proximity signal and origin signal are captured from the external input
connector and zero return is performed.
Both open collector and differential driver output origin input signals can be input.
In this mode, operation is started at high-speed zero return as shown below, and deceleration
operation is performed at the edge of the origin proximity signal. After escape from origin proximity,
the origin signal is counted, and operation is stopped immediately by the origin signal when the preset
count (address A+0004, 0005 of parameter 1) is reached to confirm the origin.
