6.2 NextMove ESB indicators

6.2.1 Status display

The Status LED normally displays the unit’s node number. To display information
about a specific axis, use the

LED

keyword (see the MintMT help file). When a specific

axis is selected, the following symbols may be displayed by the Status LED. Some
characters will flash to indicate an error.

Spline. A spline move is being performed. See the

SPLINE

keyword and related

commands.

Axis enabled.

Torque mode. The NextMove ESB is in Torque mode. See the

TORQUE

keyword and

related commands.

Hold to Analog. The axis is in Hold To Analog mode. See the

HTA

keyword and related

commands.

Follow and offset. When an axis is following a demand signal it may be necessary to
advance or retard the slave in relation to the master. To do this an offset move is
performed in parallel with the follow. See the

FOLLOW

and

OFFSET

keywords.

Circle. A circle move is being performed. See the

CIRCLEA

or

CIRCLER

keywords.

Cam. A Cam profile is being profiled. See the

CAM

keyword.

General error. See the

AXISERROR

keyword. The motion toolbar displays the status of

AXISERROR

, which is a bit pattern of all latched errors. See also the

Error Log

topics in

the help file.

Error input. The

ERRORINPUT

has been activated and generated an error.

Flying shear. A flying shear is being profiled. See the

FLY

keyword.

Position following error. A following error has occurred. See the

AXISERROR

keyword

and associated keywords. Following errors could be caused by a badly tuned
drive/motor. At higher acceleration and deceleration rates, the following error will
typically be greater. Ensure that the drive/motor is adequately tuned to cope with these
acceleration rates.
The following error limit can be adjusted to suit your application (see the

FOLERRORFATAL

and

VELFATAL

keywords). Following error could also be the cause

of encoder/resolver loss (see also the

FEEDBACKFAULTENABLE

keyword).

Follow mode. The axis is in Follow mode. See the

FOLLOW

keyword.

Homing. The axis is currently homing. See the

HOME

keyword.

Incremental move. An incremental move is being profiled. See the

INCA

and

INCR

keywords.

Jog. The axis is jogging. In the Mint help file, see the topics

JOG

,

JOGCOMMAND

and

Jog mode

.
