20144 Channel %1 block %2 motion synchronous action: system variable

access not possible

Parameters: %1 = Channel number

%2 = Block number

Definitions: When using system variables, it is assumed that a read/write operation can access the required data

successfully. In accesses to encoder actual values or digital I/Os, the result depends on the availability

of the corresponding hardware components. If an access within synchronized actions does not return

a valid value, alarm 20144 is output. Outside synchronized actions, such a read/write access causes

block execution to be interrupted until the result is available. Block execution is subsequently contin-

ued.

Reaction: NC Start disable in this channel.

Interface signals are set.

Alarm display.

NC Stop on alarm.

Remedy: Before reading/writing system variables, ensure that it is possible to access the required hardware

components.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

20145 Channel %1 block %2 motion synchronous action: arithmetic error

Parameters: %1 = Channel number

%2 = Block number

Definitions: In calculating an arithmetic expression for a motion synchronous action, an overflow has occurred

(e.g. division by zero).

Reaction: NC Start disable in this channel.

Interface signals are set.

Alarm display.

NC Stop on alarm.

Remedy: Correct error in expression.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

20146 Channel %1 block %2 motion synchronous action: nesting depth

exceeded

Parameters: %1 = Channel number

%2 = Block number

Definitions: For calculating arithmetic expressions in motion synchronous blocks, an operand stack with a fixed

set size is used. With very complex expressions, this stack can overflow.

Reaction: NC Start disable in this channel.

Interface signals are set.

Alarm display.

NC Stop on alarm.

Remedy: Correct error in expression.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

20147 Channel %1 block %2 motion synchronous action: command not

executable

Parameters: %1 = Channel number

%2 = Block number

Definitions: One of the commands for the synchronous action block cannot be executed, e.g. it is not possible to

perform a Reset to the synchronous action.

Measurement level 2

- Embargo version does not allow measurement from a synchronized action

- MEASA was programmed in a synchronized action

- Measurement is already active
