No.
1 = Drive is running at zero speed, ie. the absolute value
of par. 90.1 Motor speed for control has remained below
21.6 Zero speed limit for longer than 21.7 Zero speed
delay.
Note:
• This bit is not updated when mechanical brake
control is enabled by par. 44.6 and the drive is
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 > -[21.6].

1 = Drive is running in forward direction above zero
speed limit, ie. [90.1] > +[21.6].
Forwardb1
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)Out of windowb3
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)
