170 Parameters
06.19 Speed control
status word Speed control status word.
This parameter is read-only. -
0000h…FFFFh Speed control status word. 1 = 1
No. Name/Value Description Def / FbEq16
Bit Name Description
0 Zero speed 1 = Drive is running at zero speed, ie. the absolute value of par. 90.01
Motor speed for control has remained below 21.06 Zero speed limit for
longer than 21.07 Zero speed delay .
Notes:
• This bit is not updated when mechanical brake control is enabled by
par. 44.06 and the drive is modulating.
• During a ramp stop when the drive is running forward, the delay
count runs whenever [ 90.01 ] < [ 21.06 ]. From the reverse direction,
the delay count runs whenever 90.01 > -[ 21.06 ].
1 Forward 1 = Drive is running in forward direction above zero speed limit, ie.
[
90.01 ] > +[ 21.06 ].
2 Reverse 1 = Drive is running in reverse direction above zero speed limit, ie.
[
90.01 ] < -[ 21.06 ].
3 Out of window 1 = Speed error window control active (see par. 24.41 )
4 Internal speed
feedback 1 = Estimated speed feedback used in motor control, ie. estimated
speed is selected by par.
90.41 or 90.46 , or selected encoder has
faulted (par. 90.45 )
0 = Encoder 1 or 2 used for speed feedback
5 Encoder 1
feedback 1 = Encoder 1 used for speed feedback in motor control
0 = Encoder 1 faulted or not selected as source of speed feedback
(see par.
90.41 and 90.46 )
6 Encoder 2
feedback 1 = Encoder 2 used for speed feedback in motor control
0 = Encoder 2 faulted or not selected as source of speed feedback
(see par.
90.41 and 90.46 )
7 Any constant
speed request
1 = A constant speed or frequency has been selected; see par. 06.20 .
8 Follower speed
corr min lim 1 = Minimum limit of speed correction (in a speed-controlled follower)
has been reached (see par.
23.39 … 23.41 ).
9 Follower speed
corr max lim 1 = Maximum limit of speed correction (in a speed-controlled follower)
has been reached (see par.
23.39 … 23.41 ).
