Acceleration/Deceleration ramp 2 shape “ramp 2 shape”
These ramp times and ramp shapes are used when the second ramp time is activated
by digital input “Acc/Dec Time Sel”
P1.3.9
1257
Inching ramp “Inching Ramp”
This parameter defines acceleration and deceleration times when inching is active.
Inching function will start the drive to reference without additional start command
regardless of control place. Inching function requires enabling from digital input before
command is accepted. Inching is also disabled if there is a start command active on
the active control place.
Other parameters for inching:
•
Parameter: Inching reference 1
•
Parameter: Inching reference 2
•
Digital input selection: Enableinching
•
Digital input selection: inching 1
•
Digital input selection: inching 2

Reduction of acceleration and deceleration times
Acceleration and deceleration times can be reduced with the input signal.
Input signal level zero means ramp times set by parameters. Maximum level equals
one tenth of the value set by parameter.
