2130 5V/24V encoder or 15V D/A converter undervoltage

Definitions: A failure has occurred in the power supply to the encoder (5V/24V) or D/A converter (+/-15 V).

Reaction: NC not ready.

The NC switches to follow-up mode.

Mode group not ready, also effective for single axes

NC Start disable in this channel.

Axes of this channel must be re-referenced.

Interface signals are set.

Alarm display.

NC Stop on alarm.

Remedy: Please inform the authorized personnel/service department. Check the encoder and cable for short-

circuits (the fault must not recur when you remove the cable). Check the voltage supply.

Program Con-

tinuation:

Switch control OFF - ON.

2140 The actual service switch position forces the SRAM to be cleared at the

next Power On (general reset active)

Definitions: The initialization switch is currently set to overall reset. This means that the module's SRAM is deleted

with the next module reset. The NC data memory is cleared during this operation.

Reaction: NC not ready.

Interface signals are set.

Alarm display.

Remedy: Reset initialization switch to zero.

Program Con-

tinuation:

Alarm display showing cause of alarm disappears. No further operator action necessary.

2190 Hardware plug-in module for communication with the digitizer missing

Definitions: MD $MN_ASSIGN_DIGITIZE_TO_CHAN was used to activate the digitizing function by assigning it

to a channel. The function requires a hardware module (RS422 board plugged into the NCU) for com-

munication with the digitizing unit. This module was not found when booting.

Reaction: Interface signals are set.

Alarm display.

Remedy: Please inform the authorized personnel/service department. Plug in communications module or can-

cel channel assignment.

Program Con-

tinuation:

Switch control OFF - ON.

2194 Link axis active and $MN_MM_SERVO_FIFO_SIZE != 3

Definitions: At least one axis is to be distributed via NCU link, then the machine data

$MN_MM_SERVO_FIFO_SIZE must be 3. Occurs only with an NCU link system.

Reaction: NC not ready.

Channel not ready.

NC Start disable in this channel.

Interface signals are set.

Alarm display.

NC Stop on alarm.

Remedy: Set $MN_SERVO_FIFO_SIZE to 3.

Program Con-

tinuation:

Switch control OFF - ON.

2200 Channel %1 fast punching/nibbling not possible in several channels

Parameters: %1 = Channel number

Definitions: An attempt was made to activate fast nibbling or punching in a channel while it has already been active

in another channel. Fast punching and nibbling is only possible simultaneously in the same channel.

Reaction: NC Start disable in this channel.

Interface signals are set.

Alarm display.

NC Stop on alarm.

Remedy: Fast nibbling and punching simultaneously in 1 channel only.
