196 Actual signals and parameters
2203
DECELER TIME 1
0.0 … 1800.0 s 0.1 s 30.0 s
Sets the deceleration time for maximum frequency to zero for ramp pair 1.
• Actual deceleration time also depends on parameter 2204 RAMP SHAPE 1.
• See parameter 2008 MAXIMUM FREQ.
2204
RAMP SHAPE 1
0 … 1000.0 s 0.1 s 0.0
Selects the shape of the acceleration/deceleration
ramp for ramp pair 1. See B in the figure.
• Shape is defined as a ramp, unless additional
time is specified here to reach the maximum
frequency. A longer time provides a softer
transition at each end of the slope. The shape
becomes an s-curve.
• Rule of thumb: 1/5 is a suitable relation between
the ramp shape time and the acceleration ramp
time.
0.0 = LINEAR – Specifies linear
acceleration/deceleration ramps for ramp pair 1.
0.1…1000.0 – Specifies s-curve
acceleration/deceleration ramps for ramp pair 1.
2205
ACCELER TIME 2
0.0 … 1800.0 s 0.1 s 60.0 s
Sets the acceleration time (s) for zero to maximum frequency for ramp pair 2. See
parameter 2202 ACCELER TIME 1.
2206
DECELER TIME 2
0.0 … 1800.0 s 0.1 s 60.0 s
Sets the deceleration time for maximum frequency to zero for ramp pair 2. See
parameter 2203 DECELER TIME 1.
2207
RAMP SHAPE 2
0 … 1000.0 s 0.1 s 0.0
Selects the shape of the acceleration/deceleration ramp for ramp pair 2. See
parameter 2204 RAMP SHAPE 1.
2208
EMERG DEC TIME
0.0 … 1800 s 0.1 s 1.0 s
Sets the deceleration time for maximum frequency to zero for an emergency.
• See parameter 2109 EMERG STOP SEL.
• Ramp is linear.
