Change over to second master speed
• By setting bEnable2ndSpeedSet to TRUE, the master speed 1 (C05103/1) is changed to master
speed 2 (C05103/2).
• Ramp functions are active.
• The function can be used e.g. for applications with reduced machine speed.
Second master speed for manual jog
• A change-over to master speed 2 via input bEnable2ndSpeedSet has also an effect on the "Ma-
nual jog" function:
• Master speed 2 supersedes the manual speeds set in C05104/1 and C05104/2.
• The direction of rotation is defined by the inputs bManualJogCw (positive) or bManualJogCcw
(negative).
5.100.2 Monitoring for counter overflow
This function extension will be available from library V2.02!
If the machine parameters transferred to the FB via the AxisData input are changed afterwards (e.g.
the gearbox factors), this may cause a counter overflow when the speed and position values defined
via parameters are converted from the real unit to the internal unit.
The FB causes a corresponding error message in case of an internal counter overflow due to a chan-
ged measuring system:
