Activating override
"Override" is the change of profile parameters and their acceptance during the positioning

process.

r

When the input POS_bEnableOverride is set to TRUE, a speed and acceleration override

occurs according to the override values applied to the inputs POS_dnSpeedOverride_n

and POS_dnAccOverride_n.
– The override values represent percentage multipliers with regard to the current

profile parameters for speed and acceleration.

– For override values ≤ 1 % a status bit is set.
– Override values ≤ 0 % are set internally to 0 %.
– Changes of the override values are accepted in each cycle.

r

When the input POS_bEnableOverride is reset to FALSE again, the speeds and

accelerations defined via the profile parameters are executed again. The drive is

immediately accelerated from the override speed to the speed set in the profile.

Note!

The online change of speed and acceleration is effective from the profile start to

the beginning of the deceleration phase. Thus, the deceleration phase cannot be

changed via an override!
• In case of an override value of 0 % for speed, the drive is braked to standstill.
• In case of an override value of 0 % for acceleration, no acceleration takes place

anymore.
