Signal name, description PROFIBUS bitposn–setFct. No.
Ramp–up time zero 7 x x STW2.4
The ramp–function generator (RFG) can be switched–in and out via this input signal.
1 signal Ramp–function generator off
This acts just like a ramp–up and ramp–down of the ramp–function generator of 0 ms.
0 signal Ramp–function generator on
Integrator inhibit, speed controller 8 x x STW2.6
The integral component of the speed controller can be inhibited or enabled using this input signal.
1 signal Integrator inhibit, speed controller
0 signal The speed controller integrator is not inhibited
Note:
For a 1 signal, the integral component of the speed controller is deleted (cleared) and the integrator is
inhibited.

Note:
The bits, which are not assigned to an input terminal, are treated just like a 0 signal.
To change over, e.g. from parameter set 0 to 1, only the signal of the 1st input is necessary.
In order to ensure that the function changes over in a controlled fashion (identified as being simulta-
neous) the switching operation of the inputs must be completed with one interpolation clock cycle
(P1010).
The ”parameter set changeover” function is described in Chapter 6.10.
