Alarm reaction
A technology alarm always contains an alarm reaction, which describes the impact on the
technology object. The alarm reaction is specified by the system.
The following list shows possible alarm reactions:
●
No reaction (warnings only)
<TO>.ErrorDetail.Reaction = 0
The processing of Motion Control jobs continues. The current motion of the axis can be
influenced, e.g. by limitation of the current dynamic values to the configured limit values.
●
Stop with current dynamic values
<TO>.ErrorDetail.Reaction = 1
Active motion commands are aborted. The axis is braked with the dynamic values that
are pending in the Motion Control instruction, and brought to a standstill.
●
Stop with maximum dynamic values
<TO>.ErrorDetail.Reaction = 2
Active motion commands are aborted. The axis is braked with the dynamic values
configured under "Technology object > Extended parameters > Dynamic limits", and
brought to a standstill. The configured maximum jerk is taken into account at the same
time.
●
Stop with emergency stop ramp
<TO>.ErrorDetail.Reaction = 3
Active motion commands are aborted. The axis is braked with the emergency stop
deceleration configured under "Technology object > Extended parameters > Emergency
stop ramp", without any jerk limit, and brought to a standstill.
●
Remove enable
<TO>.ErrorDetail.Reaction = 4
The setpoint zero is output, and the enablement is removed. The axis is braked
depending on the configuration in the drive, and is brought to a standstill.
●
Follow-up setpoints
<TO>.ErrorDetail.Reaction = 5
Active motion commands are aborted. The actual values supplied by the drive are
automatically tracked as setpoints. The actual values are not monitored at the controller
end.
