4.3.6 Device Table Information in Device Changeover Mode

During changeover mode operation, in a case such as when the

feeder runs out of parts, the original table will change and a display

like the one below will be displayed. This display will not

disappear until parts have been set and the program has been

changed.

5. Zero Setting

This chapter describes the zero setting procedure.

Servomotors control the position of each of the FCP IV-3’s six axes (X, Y, C, D1,

D2 and Z). The positions of these axes are cleared from the machine’s memory

whenever the power is turned off; therefore, the machine must determine the

position of each axis each time the power is turned on. The procedure used to

do this is known as zero setting.

The method of zeroing an axis is described below, using the X axis as an

example.

(1) If the X-axis deceleration-point sensor input is ON, the axis initially moves

in the negative (-X) direction until this input turns OFF.

(2) The X axis moves in the positive (+X) direction and decelerates when the

X-axis deceleration-point sensor turns ON.

(3) After deceleration, the X axis inches in the positive (+X) direction.

(4) The X axis stops moving when the encoder outputs the Z signal. (The Z

signal is output only once per motor revolution.) This X-axis position

becomes the zero position.

Note: Zero setting is not performed on the FQ axis.

Part 1

The 6 axes are set in the following order: X, Y, C, D1, D2, Z. During zero setting

a display like the one shown below will appear in the second display area.

After zero setting is complete, the D1 and D2 axes tables will move to their

respective resupply positions and the shutters will then lower.
