cause it to be performed in the selected direction.

- The signals are

valid when jog feed (JOG) is selected. They indicate the direction of

feed, from 0 to 1 causes and keeps movement in the corresponding

direction at a feedrate specified by the override signals *0V1 to *0V8 or

the manual rapid traverse selection signal RT, provided the signal is 1.

CAUTION

1. Simultaneously setting +X and -X to 1 results in neither

direction being selected (dquivalent to when both are

0).

2. If a feed axis selection signal becomes 1 before the jog

feed selection signal (JOG) becomes 1, it must be reset

to 0 before the feed axis selection signal is set. The

servo unit begins feeding when the JOG signal rises.

Clamp/unclamp state output signal

When the servo unit requests clamping/unclamping of the machine,

using the UCPC2 signal, the host actually clamps/unclamps the

machine.

Upon the completion of clamp/unclamping, it reports it to the servo unit,

which then proceeds to the next processing.

The signal is set to 1 when machine is undamped.

When it is clamped, the signal is reset to 0.

See the timing chart for the

function codes for peripheral equipment control.

CAUTION

The UCPS2 signal is valid when the NCLP parameter (bit 1 of

parameter No.003) .is 0.

SA

X65.6

Automatic operation start signal The host starts function code

commands, such as part of peripheral equipment control ATC

operations and point positioning. Specifically, the host issues a direct

command to start 32-block buffering. When the ST signal is set to 1

then reset to 0 again, the servo unit begins operating.

CAUTION

It is also possible to start operation at the rising edge (form

off to ton) of the ST signal as specified by the STON

parameter (bit 7 of parameter No.003)

OP

X65.7

External reset signal

This signal resets the servo unit.

• When the signal becomes 1, the servo unit operates as follows :

- The servo unit immediately decelerates axis movement to a

stop.

- After as. stop, the servo unit is reset, then the following are

canceled :

) Function code commands being executed, buffered, and

sent as an input signal.

) Alarm condition (if any).

- While the external reset signal is 1, jog and function code

commands cannot be issued.

RST

X66.1

Emergency stop signal

This signal brings the control unit to an emergency stop.

- The control unit decelerates axis movement to a stop immediately.

- A reset is applied after the stop.

- When the emergency stop signal is 0, the servo preparation

completion signal SA is also 0, because the servo system is not

operating, the amount of movement is reflected in the current

position coordinates held in the control unit (follow-up)

- While the emergency stop signal is 0, jog and function code

commands cannot be issued.

X65.2

Servo-off command signal

The host turns off the servo circuit for a controlled axis, that is, shuts off

the current to the servo motor of the controlled axis. This disables

positioning control. Position detection continues, however. So, the

current position will not be lost.

The servo motor remains off while the signal is 1. If the machine is

moved by the application of external force, its coordinates are shifted,

because positioning control does not work during the servo-off state.

How the shifted machine coordinates are handled can be selected by a

parameter, as follow:

1. The machine coordinate shift is recorded in an error counter.

When the servo-off signal becomes 0, the machine moves to cancel out

the error recorded in the error counter.

2. Follow-up is performed.

The machine coordinate shift is regarded as being the result of a

command, and the control unit adjusts its current position data so that

the error counter becomes 0. With this method, the machine remains in

a shifted position even after the servo-off signal becomes 0. However,

the machine moves to the correct position the next time an absolute

command is issued, because the control unit has information about the

correct position.

[USE]

Generally, method (1) above is used to prevent excessive current

flowing through the servo motor when it is clamped mechanically with a

force stronger than the servo motor can generate. Usually, the host

keeps the inter lock signal at 0 while the servo-off signal is 1. Generally,

method (2) is used to operate the machine by rotating the motor with a

handle feed mechanism.

*ILK

Y65.3

Inter lock signal

The host stops sending jog feed and function code commands.

• When the *ILK signal is 0, the host resets jog feed and function code

command signals to 0 to decelerate and stop controlled axis feed.

When it becomes 1, movement is resumed immediately. No command

other than a move command is affected.

CAUTION

The interlock signal is valid when jog feed (-X or +X) is being

performed based on the jog feed selection signal (JOG).

V READY OFF alarm ignore signal

This signal is used to disable the detection of "Servo alarm (No.0401): V

ready off" for the controlled axis.

When the signal becomes 1, the control unit behaves as follows:

• Even when the servo amplifier preparation completion signal is off, "servo

alarm (No.401) : V ready off" is not detected. The Servo preparation

completion signal SA becomes 0, however.(This signal can be held at 1

using the SAK parameter (bit 0 of parameter No.004)
