NOTE

With the S5-digit analog output invert input

it is possible to

provide minus (–) analog outputs for the SSTP, GRS, and GSC inputs.

It takes no more than about

ms for the analog voltage to change

in response to the SSTP, GRS, or GSC input.
3. The “*.

input is provided by setting parameter

D5 to 1.

21. 3.4.3 SPINDLE SPEED REACHED INPUT (SAGR #31116)

When a part program is executed in the automatic operation mode in cases where the con-
trol uses the

command, the SAGR input indicates that the specified spindle rotating

speed is reached at the cutting start point.

When cutting starts (the positioning command is superseded by the cutting command), the

control waits for the delay timer to time out as defined by parameter

and starts cut-

ting after verifying that the SAGR input is closed.

NOTE

To support the above operation based on the SAGR input, para-

meter

D7 must be set to 1. If the parameter is set to O, the

SAGR input is disregarded.
2. In the G96 mode, the SAGR input is always checked when the posi-
tioning command is superseded by the cutting command.

In the G97 mode, the SAGR input check is performed at the time of

positioning-to-cutting command changeover only in cases where the

spindle ratating speed at the end of positioning differs from that prevail-
ing at the beginning of positioning.

21. 3.4.4

SPINDLE SPEED OVERRIDE INPUTS (SPA # 31110, SPB # 31111, SPC # 31112,

SPD #31113,

#31114)

When a part program is executed in the automatic operation mode in cases where the control

uses the

command, the captioned inputs provide a 50 to 120% override for the S com-

mand.
With parameters, it is possible to provide a 10 to 200% override.
