Bit Name Information
0 Speed act
neg
1 = Actual speed is negative.
1 Zero speed 1 = Actual speed has reached the zero speed limit (parameters 19.06 Zero
speed limit and 19.07 Zero speed delay).
2 Above limit 1 = Actual speed has exceeded the supervision limit (parameter 19.08
Above speed lim).
3 At setpoint 1 = The difference between the actual speed and the unramped speed
reference is within the speed window (parameter 19.10 Speed window).
4 Reserved
5 PI tune
active
1 = Speed controller autotune is active.
6 PI tune
request
1 = Speed controller autotune has been requested by parameter 23.20 PI
tune mode.
7 PI tune
done
1 = Speed controller autotune has been completed successfully.
8 Speed not
zero
1 = Speed controller autotune has been requested when the drive was
running, but zero speed has not been reached within preset maximum time.
9Spd tune
aborted
1 = Speed controller autotune has been aborted by a stop command.
10 Spd tune
timeout
1 = A speed controller autotune timeout has occurred.
• Autotune was requested while drive was running, but a stop command
did not follow
• Stop command has been issued, but drive has not reached zero speed
• Drive does not accelerate and decelerate according to the given
reference during autotune.
Bit Name Information
0 Torq lim 1 = Drive torque is being limited by the motor control (undervoltage control,
current control, load angle control or pull-out control), or by the torque limit
parameters in group 20 Limits.
1 Spd ctl tlim
min
1 = Speed controller output minimum torque limit is active. The limit is
defined by parameter 23.10 Min torq sp ctrl.
2 Spd ctl tlim
max
1 = Speed controller output maximum torque limit is active. The limit is
defined by parameter 23.09 Max torq sp ctrl.
3 Torq ref
max
1 = Torque reference (03.11 Torq ref ramped) maximum limit is active. The
limit is defined by parameter 24.03 Maximum torq ref.
4 Torq ref min 1 = Torque reference (03.11 Torq ref ramped) minimum limit is active. The
limit is defined by parameter 24.04 Minimum torq ref.
5Tlim max
speed
1 = Torque reference maximum value is limited by the rush control, because
of maximum speed limit 20.01 Maximum speed.
6Tlim min
speed
1 = Torque reference minimum value is limited by the rush control, because
of minimum speed limit 20.02 Minimum speed.
