When monitoring is started, the set acceleration is calculated as a straight line V

parameters. If the actual

Safely limited acceleration range monitoring (SAR-M)
The monitoring function
Safely limited acceleration monitoring
monitors the speed
change per time unit.
In contrast to the monitoring function SLA-M, safely limited acceleration range monitoring
monitors not only a limit value but also the upper and lower limit value simultaneously. Both
the acceleration and the deceleration can be monitored.
Otherwise the functionality is the same as the monitoring function SLA-M.
4 SAR-M elements can be configured per axis in the PNOZmulti Configurator.
