7.5.65.4 S ramp
The linear ramp function generator is connected to a PT1 element. This arrangement implements an
S ramp for an almost jerk-free acceleration and deceleration.
• The PT1 element is switched on and off via C0134.
• The time constant is set via C0182.
7.5.65.5 Arithmetic operation
The output value is led to an arithmetic module. This module links the main setpoint and theadditional
setpoint arithmetically. The arithmetic operation is selected via C0190 (see the following table).
C0190 Function Example
0 Output = X (Y is not processed) -
1 Output=X+Y 100 % = 50 % + 50 %
2 Output = X - Y 50 % = 100 % - 50%
3* Output = X * Y 100 % = 100 % * 100%
4* Output = X/|Y| 1 % = 100 % / 100%
5 Output = X/(100% - Y) 200 % = 100 % / (100 % - 50 %)
*) Please observe the note for C0190 = 3, 4 in the following chapter
