21614 Channel %1 axis %2 hardware limit switch %3

Parameters: %1 = channel number

%2 = axis name, spindle number

%3 = string (+, - or +/-)

Definitions: The VDI signal "Hardware limit switch" has been set at the NC/PLC

interface (V 380x1000.0 or.1).

Reaction: NC Start disable in this channel.

Alarm display.

Remedy: 1.With axes that have already been referenced, the software limit switch 1 or 2 should respond before

the hardware limit switch is reached.

Check MD 36110 POS_LIMIT_PLUS, MD 36100 POS_LIMIT_MINUS, MD 36130 POS_LIMIT_

PLUS2 and MD 36120 POS_LIMIT_MINUS2 as well as the interface signal for selection of the 1st/2nd

software limit switch

(V 380x1000.2 and .3) and correct if necessary (PLC user program).

2.If the axis has not yet been moved to the reference point, it is possible to depart from the hardware

limit switch in the opposite direction in JOG mode.

3.Check PLC user program and the connection from the switch to the PLC input module, provided the

axis has not yet reached the hardware limit switch at all.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

21615 Channel %1 axis %2 taken from traverse mode to follow-up mode

Parameters: %1 = channel number

%2 = axis name, spindle number

Definitions: This axis has been switched from traverse mode and to "Follow-up" mode, for instance, because the

pulse enable for the drive has been reset.

Reaction: NC Start disable in this channel.

Interface signals are set.

Alarm display.

NC Stop on alarm.

Remedy: -

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

21616 Channel %1 block %2 overlaid motion active at transformation

switchover

Parameters: %1 = Channel number

%2 = Block number, label

Definitions: The overlaid motion in the BCS changes its significance because of the transformation change and

can therefore lead to undesired axis movements.

Reaction: Local alarm reaction.

Interface signals are set.

Alarm display.

NC Stop on alarm.

Remedy: Take out the overlaid movement.

Program Con-

tinuation:

Clear alarm with NC START or RESET key and continue the program.

21617 Channel %1 block %2 transformation does not allow to traverse the pole

Parameters: %1 = channel number

%2 = block number, label

Definitions: The specified curve passes through the pole or a forbidden area of the transformation.

Reaction: Local alarm reaction.

NC Start disable in this channel.

Interface signals are set.

Alarm display.

NC Stop on alarm.

Remedy: Modify part program (if alarm has occurred in AUTO mode).

To escape from the alarm position, transformation must be deselected (it is not enough to try a RESET

if the transformation remains active when RESET is applied).
