Maximum velocity
The maximum velocity of an axis is defined using parameter p2571. The velocity should not
be set to be greater than the maximum speeds in r1084 and r1087.
The drive is limited to this velocity if a higher velocity is specified or programmed via the
override (p2646) for the reference point approach or is programmed in the traversing block.
Parameter p2571 (maximum velocity) defines the maximum traversing velocity in units
1000 LU/min. If the maximum velocity is changed, then this limits the velocity of a traversing
task that is presently being executed.
This limit is only effective in the positioning mode for:
● Jog mode
● Processing traversing blocks
● Direct setpoint input/MDI for positioning/setting-up
● Reference point approach
Maximum acceleration/deceleration
Parameter p2572 (maximum acceleration) and p2573 (maximum deceleration) define the
maximum acceleration and the maximum deceleration. In both cases, the units are 1000
LU/s
Both values are relevant for:
● Jog mode
● Processing traversing blocks
● Direct setpoint input/MDI for positioning and setting-up
● Reference point approach
The parameters do not have any effect when faults occur with the fault responses OFF1 /
OFF2 / OFF3.
In the traversing blocks mode, the acceleration and deceleration can be set in multiple
integer steps (1 %, 2 % ... 100 %) of the maximum acceleration and deceleration. In "direct
setpoint input/MDI for positioning and setting up" operating mode, the acceleration/delay
override (assignment of 4000 hex = 100%) is specified
Note
A maximum acceleration and/or delay dependent on current velocity (zigzag acceleration) is
not supported.
Note
When using the PROFIdrive message frame 110, the velocity override is already connected
and has to be supplied by the message frame.
