L_SdRampGeneratorAny - ramp function generator - S-ramp
This FB is a ramp function generator with S-shaped ramps for limiting the increase of analog signals
over time. The S-shape of the ramps results from a trapezoidal acceleration.
• This FB is an advanced version of the
FB:
• Depending on the interconnection of AxisData, setpoints can be defined as scaled signals
(_n) or speeds (_s).
• Separate acceleration and deceleration times can be set via C04332/1 and C04332/2.
• Separate S-ramp times for acceleration and deceleration to achieve jerk-free acceleration can
be set in C04333/1 and C04333/2.
• The ramp function generator has a setting function for directly loading the value into the inter-
nal ramp generator.
• At the dnDeltaOut output, gradient dy/dt of the dnOutput output signal is provided. This signal
can e.g. be used for torque feedforward control after being amplified via the
Inputs

Identifier/data type
Information/possible settings
dnInput
DINT
Input signal (scaled signal or speed)
• Scaling:
100 % ≡ 2
30
≡ 1073741824 (without AxisData)
15000 min
-1
≡ 2
26
≡ 67108864 (with AxisData)
bLoadStartValue
BOOL
Initialising ramp function generator
FALSE The ramp function generator runs with the Ti times set from the va-
lue loaded via dnStartValue to the value at dnInput.
TRUE At the dnOutput output, dnStartValue is provided. dnDeltaOut re-
mains at 0 % or 0 min
-1
, respectively.
dnStartValue
DINT
Starting value for the ramp function generator (scaled signal or speed)
• Acceptance when bLoadStartValue = TRUE
• Scaling:
100 % ≡ 2
30
≡ 1073741824 (without AxisData)
15000 min
-1
≡ 2
26
≡ 67108864 (with AxisData)
AxisData
Machine parameters
• If this input is not interconnected, the FB uses scaled signals.
• If the FB receives machine parameters via this input, the FB uses speed signals in-
stead.
• For accepting the machine parameters of the drive/motor, connect this input
with the output DI_AxisData of the SB LS_DriveInterface.
• The machine parameters of a master drive can be displayed with the
FB
. In this case, the FB output AxisData must be connected to
this input.
