6.2.3 FB 404 MC_Stop - Stop axes / prevent new motion commands
Purpose
• The "MC_Stop" technology function stops all motions and ramps the axis down
to standstill. The standstill position is not defined.
• The command is done (Done = TRUE), when the axis is in standstill and
Execute = FALSE is set, i.e. as long as Execute = TRUE is set, startup of the
axis is inhibited. This also applies if the axis was locked in the meantime with
MC_Power and then re-enabled.
• The dynamic response within the motion stop operation is determined at the
input parameters Jerk and Deceleration.
Applicable to
• Velocity axes
• Positioning axes
• Synchronization axes
Requirements
• For dynamic stop, the axis must be enabled for position or velocity control. The
axis can not be ramped down dynamically when it is in following mode or
locked state!
