The same calculation can be done for the deceleration time (using
Dec Delta speed
–
Dec Delta time
and
S
dec t const
).
Speed changes (=Active ramp) are indicated by the
Ramp +
and
Ramp
- parameters.
Ramp +/- delay
Defines a delay time. It is only valid if the ramp is active.

Fwd-Rev
Changes the sign of the Ramp reference. When Fwd direction is selected the Ramp
reference is multiplied by +1. When Rev direction is selected the Ramp reference is
multiplied by-1.
Forward sign
Set the Fwd direction of the Ramp reference. It can be programmed on a digital input.
Reverse sign
Set the Rev direction of the Ramp reference. It can be programmed on a digital input.
When both Fwd and Rev sign are 0 or 1, or
Fwd-Rev
is 0 or 1, the multiplexer is 0.
The behavior of the ramp circuit is defined by the
Enable Ramp
,
Ramp In = 0
,
Ramp Out = 0
and
Freeze
ramp
parameters.
Enable Ramp
This parameter can be changed only with a disabled drive.
Enabled
The ramp is enabled.
Disabled
The ramp is disabled.
Ramp out = 0
Not active (H) Enabled ramp output.
Active (L)
The ramp ouput is immediately set to zero.
Ramp in = 0
Not active (H) Enabled ramp input. The
Ramp Ref
parameter corresponds to the
set reference.
