Data type

UNSIGNED16

Value range

1 ... 65535

Default value

0

This Index sets the form of the acceleration ramp. The value chosen must be smaller than half of
the run-up time (Sub-index 06

h

). The following diagram illustrates the relationships:

T

1

corresponds to the Sub-index 06

h

and T

2

to Sub-index 08

h

.

If T

2

= 0, then a trapezoidal acceleration ramp is used.

If T

2

=

T

2

1

then an approximately sin

This Index defines the form of the braking/deceleration ramp. The value chosen must be smaller
than half of the braking time (Sub-index 07

h

). Jolt (deceleration) limiting functions in the same way

as jolt (acceleration)
