SIMODRIVE 611 universal Description of Functions (FBU) – 04.05 Edition
For the ramp–function generator, the following signals are used:
 Input signal – Ramp–function generator enable
– Ramp–up time zero
– Ramp–up time zero for contr. enable (from SW 3.1)
 Output signal – Ramp–up completed
Reader’s note
The signals can be entered or output as follows:
 via terminals ––> refer to Chapter 6.4.2 or 6.4.5
 via PROFIBUS–DP ––> refer to Chapter 5.6.1
All of the input/output signals are shown and described in Chapter
6.4.3 and 6.4.6 and can be found in the Index under ”Input signal...” or
”Output signal...”.

1) For an active average–value filter for the speed setpoint (P1012.8=1), a setpoint step somewhat
greater than P1426 must be used in order to clearly identify the start of a new ramp–up operation.
