ECOLOAD S2

6.2. Description

MODE 1 Simulation

When this MODE is ON, the bar feeder runs feeding and bar
change cycles automatically and not controlled by either
interface signals or manual operation.
This MODE is for factory test or exhibition purpose only. When
it’s connected with the lathe,

it must always be turned OFF

0 - Turn SIMULATION OFF
1 - Turn SIMULATION ON

MODE 2 Chuck signal (A1) logic setup

0 - CHUCK signal is ON when chuck is open
1 - CHUCK signal is OFF when chuck is open.

MODE 3 CNC alarm signal (A2) logic setup

0 – Lathe alarm signal is ON when there is an alarm.
1 – Lathe alarm signal is OFF when there is an alarm.

MODE 4 M-function (A3) logic setup 1 of 2

“M-function” represents a signal in addition to chuck

signal for confirming lathe chuck status. (also refer to
MODE 7 for further information)

0 – M-function signal is ON when the lathe activates M-function.
1 – M-function signal is OFF when the lathe activates M-
function.

MODE 5

This parameter intentionally left blank.
