SIMODRIVE 611 universal Description of Functions (FBU) – 04.05 Edition
The velocity of an axis can be influenced using the velocity override or
also known as just override.
Note
The maximum traversing velocity is limited by the maximum velocity
set in P0102.
The override has no effect on the acceleration/deceleration, i.e. when
the override is doubled, the axis velocity is doubled, but the positioning
time is not halved.
The override can be entered as follows:
Analog input, terminals 56.x/14.x
The following prerequisites must be fulfilled to enter an override via
the analog input:
– Set P0607 to 2 (refer to Chapter 6.6):
The analog input is declared as override input.
– Set P0111 and P0112:
The reference voltage and normalization is defined.
– SimoCom U may not have the master control.
PROFIBUS–DP
The override is entered via the ”Over” control word.
SimoCom U
SimoCom U must have the master control to set an override.
