The software limit switches must remain de–activated so that the drive
can always rotate endlessly. This is the reason that in the speed set-
point mode the drive must be parameterized as rotary axis and be de–
referenced.
For the ramp–function generator, the following signals are used:
 Input signals:
– Ramp–function generator enable (STW.4 = 1)
– Ramp–function generator start/ramp–function generator stop
(STW.5 = 1)
– Enable setpoint/inhibit setpoint (STW.6 = 1)
 Output signals:
– Speed in the tolerance bandwidth/speed outside the tolerance
bandwidth (ZSW.8)
– Ramp–up completed/ramp–up not completed (ZSW.10)
Delay time P1427:
Ifnt > P1427, then ”ramp–up completed” (ZSW.10 = 1)
