Speed Reference Display
Acceleration Time
4. Parameter Description
Displays the speed reference at the output of the ramp generator in
rpm.
When the modulation is switched off the setpoint 0 rpm is displayed.
Resolution: 0,5 rpm
positive speed: direction of rotation "forward"
negative speed: direction of rotation "reverse"
n
[rpm]
Defines the time needed to accelerate from 0 to 1000 rpm. The
actual acceleration time is proportional to the speed change (
