Figure 6.6.1 : Ramp circuit
The ramp (reference value integrator) determines the acceleration and deceleration times of the drive. These
times can be set independently of each other.
An additional ramp is provided for a quick stop. This ramp can only be activated via the serial interface or a
field bus.
The ramp can either be linear or S-shaped.
The reference values can be defined in different ways:
- with the
Ramp ref 1
and/or
Ramp ref 2
reference values
- with the multi-speed function
- with the motor potentiometer function
- with the Jog function
The Ramp generator can be used in a stand alone configuration. When the Ramp generator is disabled (

ramp
= disabled), the

,
Start/Stop
and
Fast stop
commands have no more influence on Ramp
generator. In such a condition it is free to run and can be used separately.
