Input
Transmission ratio:
The transmission ratio indicates the distance travelled for one motor revolution.
Resolution = transmission
Example:
A motor with
200
pitch/revolution, is to be operated in the half step mode.
Pulses/revolution:
Transmission ratio: 4.00 mm/rev
Resolution: S = a
The maximum resolution is 1 pm/pulse.
JOG speed 1
This is the speed of travel in the mode "JOG speed 1". This speed must correspond to a
frequency less than or equal to
The following must apply:
JOG speed 2
This is the speed of travel in the mode "JOG speed
frequency less than or equal to
The following must apply:
Incremental speed (VinC):
This speed is used for the operating mode "incremental speed absolute" and "incremental
speed relative". This speed must correspond to a frequency less than
The following must apply:
Vine
C
Reference speed
This speed is used in the "reference point approach" until the reference point marker
the start-stop frequency and less than or equal to the maximum frequency.
The relationship between frequency and speed is calculated from the machine data "pulses/revo-
lution" and "transmission ratio".
