2.4.47.6 S−ramp
A PT1 element is connected to the linear ramp function generator. This arrangement implements an
S−ramp for an almost jerk−free acceleration and deceleration.
l The PT1 element is switched on/off under C0134.
l The time constant is set under C0182.
2.4.47.7 Arithmetic operation
The output value is led to an arithmetic function which combines the main setpoint and the additional
setpoint. The arithmetic combination is selected under 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 %)
2.4.47.8 Additional setpoint
l Via the input NSET−NADD you can combine an additional setpoint (e.g. a correction signal)
with the main setpoint.
l With NSET−NADD−INV = HIGH you can invert the signal at NSET−ADD, before it is applied to
the ramp function generator. The ramp function generator has a linear characteristic with
acceleration time T
ir
(C0220) and deceleration time T
if
(C0221).
l With NSET−LOAD = HIGH or when controller inhibit is set, the ramp function generator is set to
0 and held there, without considering the T
i
times.
