206 Actual signals and parameters
2204 RAMP SHAPE
1
Selects the shape of the acceleration/deceleration ramp 1.
The function is deactivated during emergency stop.
0.0 =
LINEAR
0.0 = LINEAR
0.1…1000.0 s
0.0: Linear ramp. Suitable for steady acceleration or
deceleration and for slow ramps.
0.1 … 1000.0 s: S-curve ramp. S-curve ramps are ideal for
conveyors carrying fragile loads, or other applications where
a smooth transition is required when changing from one
speed to another. The S-curve consists of symmetrical
curves at both ends of the ramp and a linear part in
between.
1 = 0.1 s
2205 ACCELER
TIME 2
Defines the acceleration time 2, that is, the time required for
the speed to change from zero to the speed defined by
parameter 2008 MAXIMUM FREQ.
See parameter 2202 ACCELER TIME 1.
60.0 s
0.0…1800.0 s Time 1 = 0.1 s
2206 DECELER
TIME 2
Defines the deceleration time 2, that is, the time required for
the speed to change from the value defined by parameter
2008 MAXIMUM FREQ to zero.
See parameter 2203 DECELER TIME 1.
60.0 s
0.0…1800.0 s Time 1 = 0.1 s
2207 RAMP SHAPE
2
Selects the shape of the acceleration/deceleration ramp 2.
The function is deactivated during emergency stop.
0.0 =
LINEAR
0.0 = LINEAR
0.1…1000.0 s
See parameter 2204 RAMP SHAPE 1.1 = 0.1s
2208 EMERG DEC
TIME
Defines the time within which the drive is stopped if an
emergency stop is activated. See parameter 2109 EMERG
STOP SEL.
1.0 s
0.0…1800.0 s Time 1 = 0.1 s
2209 RAMP INPUT 0 Defines the control for forcing the speed to zero with the
currently used deceleration ramp (see parameters 2203
DECELER TIME 1 and 2206 DECELER TIME 2).

No. Name/Value Description Def/FbEq
Linear ramp: Par. 2204 = 0 s
S-curve ramp:
Par. 2204 > 0 s
A rule of thumb:
A suitable relation between the ramp shape time and the
acceleration ramp time is 1/5.
