Limitations
Description
The velocity, acceleration and delay can be restricted and the software limit switches and
stop cams set.
The following restrictions exist:
●
Velocity profile limitations
–
Maximum speed (p2571)
–
Maximum acceleration (p2572) / maximum delay (p2573)
●
Traversing range limits
–
Software limit switches (p2578, p2579, p2580, p2581, p2582)
–
STOP cams (p2568, p2569, p2570)
●
Jerk limit
–
Jerk limitation (p2574)
–
Activation of jerk limitation (p2575)
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 of
1000 LU/min. Changing the maximum speed restricts the velocity of an active traversing
block.
This restriction is only effective in positioning mode during:
●
Jog mode
●
Traversing block processing
●
Direct setpoint specification/MDI for positioning/setting up
●
Reference point approach
