The Identification of Origin
OFF
････
When cylinder stops, if there is no signal feedback from sensor within t1 (Preset data,P7),
counter value will be reseted to
“0” and origin is obtained / recognized.
Generally, origin will be at the stroke end.
If origin is set within the stroke, install stopper with respect to the origin.
ON
･････
When the cylinder stops at origin, situated at the location where auto switch or limit switch
is, and sensor signal is not feedback within t1, counter value will be reset to
“0.0” and
origin is obtained.
Install the origin wire to terminal 10.

The Setting of Braking System
OFF
････
In this state, ON means brake is activated. OFF means brake is in releasing state.
If power supply of controller is cut off, the brake will be in releasing state.
If cylinder is mounted horizontally and the air balance is not achieved, when power is cut
off, the cylinder may keep moving in and out.
If cylinder is mounted vertically, when power is cut off, cylinder rod will fall to the bottom
end, due to its own weight.
ON
･････
In this state, OFF means brake is activated, ON means brake is in releasing state.
