 Acceleration/Deceleration and S curve settings
The acceleration and deceleration ramps are set in C1-, while the S curves are defined in
C2-01 to C2-04. Refer to the below.
C1-03
Time
In case that the default ramps do not match, increase or decrease, based on these defaults.
The effective ramp time can be calculated as follows:.
Refer to the figure below. In this example, E1-04 = 60 Hz and C1-01 = 4 s would yield an
effective time of 1.3 s.
 Reference and Run Source
The "LO/RE" key on the drive's operator keypad is normally used for switching from
remote mode to local mode. Local mode means frequency reference and run signal are input
from the operator panel. To use this function (e.g. for testing a motor without pump or a
pump without the remaining elevator installation) set O2-01 = 0.
