Table 10.4 Drive status word bit functions
Bit Parameter Description
0Pr 10.001
bit 0 = 0:
Drive not ok (tripped).
bit 0 = 1:
Drive ok.
1Pr 10.002
Drive active
When bit 1 = 1, the drive is in run mode.
2Pr 10.003
Zero speed
In Open Loop mode, zero speed indicates that the absolute value
of the post-ramp speed reference is at or below the zero speed
threshold.
In RFC-A and RFC-A modes, zero speed indicates that the
absolute value of speed feedback is at or below the zero speed
threshold.
3Pr 10.004
Running at or below minimum speed
In bipolar mode (Pr 01.010 = 1) Pr 10.004 is the same as zero
speed, Pr 10.003. (See above.)
In unipolar mode, Pr 10.004 is set if the absolute value of the post-
ramp speed reference (Pr 02.001) or speed feedback (Pr 03.002) is
at or below minimum speed + 0.5Hz or 5 rpm. (Minimum speed is
defined by Pr 01.007.) This parameter is only set if the drive is
running.
4Pr 10.005
Below set speed
Only set if the drive is running at below set speed. Refer to
Pr 03.006, Pr 03.007 and Pr 03.009 in the drive documentation for
more details.
5Pr 10.006
At speed
Only set if the drive is running at set speed.
Refer to Pr 03.006, Pr 03.007 and Pr 03.009 in the drive
documentation.
6Pr 10.007
Above set speed
Only set if the drive is running at above set speed. Refer to
Pr 03.006, Pr 03.007 and Pr 03.009 in the drive documentation for
more details.
7Pr 10.008
Load reached
Indicates that the modulus of the active current is greater or equal
to the rated active current, as defined in menu 4. Refer to the drive
documentation for more details.
8Pr 10.009
In current limit
Indicates that the current limits are active.
9Pr 10.010
Regenerating
Indicates that power is being transferred from the motor to the
drive.
Regen mode: Indicates that power is being transferred from the
drive to the supply.
10 Pr 10.011
Dynamic brake active
Indicates that the braking IGBT is active. If the IGBT becomes
active, this parameter will remain on for at least one second.
