Description
1 = Drive is running at zero speed, ie. the absolute value
of par. 90.1 Motor speed for control
21.6 Zero speed limit for longer than
delay.
Note:
• This bit is not updated when mechanical brake
control is enabled by par.
modulating.
• During a ramp stop when the drive is running
forward, the delay count runs whenever [90.1] <
[21.6]. From the reverse direction, the delay count
runs whenever 90.1
1 = Drive is running in forward direction above zero
speed limit, ie. [90.1] > +[21.6].
1 = Drive is running in reverse direction above zero
speed limit, ie. [90.1] < -[21.6].
1 = Speed error window control active (see par. 24.41)
1 = Estimated speed feedback used in motor control,
ie. estimated speed is selected by par.
or selected encoder has faulted (par. 90.45)
0 = Encoder 1 or 2 used for speed 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)
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)
1 = A constant speed or frequency has been selected;
see par. 6.20.
1 = Minimum limit of speed correction (in a
speed-controlled follower) has been reached (see par.
23.39...23.41).
1 = Maximum limit of speed correction (in a
speed-controlled follower) has been reached (see par.
23.39...23.41).
Constant speed/frequency status word. Indicates
which constant speed or frequency is active (if any).

This parameter is read-only.
1 = Constant speed or frequency 1 selected
1 = Constant speed or frequency 2 selected
