6.17.12.1 Override via analog input (override−AIN)
ƒ Activation of the override AIN: C3096/x.Bit0 = 1 (xxxx.xxxx.xxxx.xxx1)
ƒ Scaling: 10 V
= 16384 = 100 %
Example: Calculation of the effective speed (v
real
)
ƒ Profile traversing speed (v
prof
) = 5000 mm/s
ƒ Override−AIN = 80 %

6.17.12.2 Override via process data object (override−PDO)
ƒ Activation of the override PDO: C3096/x.Bit3 = 1 (xxxx.xxxx.xxxx.1xxx)
ƒ Scaling: 16384
= 100 %
ƒ Transmission via data word "rx_par1" (VelDirect)
Example: Calculation of the effective speed (v
real
)
ƒ Profile traversing speed (v

) = 5000 mm/s
ƒ Override−PDO = 50 %

Direct positioning without override−PDO
ƒ Transmission:
Data word "rx_par1" (VelDirect) = profile traversing speed
(Is accepted once for the profile start.)
Direct positioning with override−PDO
ƒ Transmission:
Data word "rx_par1" (VelDirect) = override PDO
(Is accepted cyclically, also during positioning.)

Special feature with the "Continuous constant travel (direct)" with override−PDO:
When the "Continuous constant travel (direct)" starts, the sign of the PDO data word
"rx_par1" determines the direction of rotation. The override influence itself continues to
be effected according to amount.
