Channel %1 block %2 motion synchronous action: system variable access not pos-
sible
%1 = Channel number
%2 = Block number
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 continued.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Before reading/writing system variables, ensure that it is possible to access the required
hardware components.
Clear alarm with the RESET key. Restart part program
Channel %1 block %2 motion synchronous action: arithmetic error
%1 = Channel number
%2 = Block number
In calculating an arithmetic expression for a motion synchronous action, an overflow has
occurred (e.g. division by zero).
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Correct error in expression.
Clear alarm with the RESET key. Restart part program
Channel %1 block %2 motion synchronous action: nesting depth exceeded
%1 = Channel number
%2 = Block number
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.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Correct error in expression.
Clear alarm with the RESET key. Restart part program
Channel %1 block %2 motion synchronous action: command not executable
%1 = Channel number
%2 = Block number
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.
