MULTI-STEP SPEED PRESETS
In order to use multi-step
speed presets, constants
no-32, no-33 & no-34
must be pro-
grammed accordingly for 2-Wire or 3-Wire control. (Constant
no-01
must be set to X X X 1.)
To use the maxi-
mum of 5 preset
speeds (in 2-Wire
control only),
constant
no-32
must be set to
03
( Multi-step Speed
Ref 1 ), constant
no-33
must be set
to
04
( Multi-step
Speed Ref 2 ), and
constant
no-34
must be set to
05
( Jog ).
For 3-Wire control, con-
stant
no-32
must be
00
( FWD/REV ). Therefore,
a maximum of 4 preset
speeds can be used, if
constant
no-33
is set to
03
( Multi-step Speed
Ref 1 ) and constant
no-
34
is set to
04
( Multi-
step Speed Ref 2 ).
Constants

no-17
Range (ea.) : 0.0 to 400.0 ( Hz )
