Status word

The SM-PROFIBUS DP-V1 status word consists of sixteen control bits some of which
are reserved. See Table 9.3 for the individual bit function descriptions.

The fieldbus status word is mapped directly from the drive status word, Pr 10.40.
Pr 10.40 is generated by the values of several individual drive status bits; Table 9.4
shows the function indicated by each bit in the status word when set to 1.

Pr 10.02
When bit 1 = 1, the drive is in run mode.
Zero speed
In Open Loop mode, zero speed indicates that the absolute value of the
Pr 10.03 post-ramp speed reference is at or below the zero speed threshold.
In Closed Loop and Servo modes, zero speed indicates that the absolute
value of speed feedback is at or below the zero speed threshold.
Running at or below minimum speed
In bipolar mode (Pr 1.10 = 1) Pr 10.04 is the same as zero speed, Pr 10.03.
(See above.)
Pr 10.04 In unipolar mode, Pr 10.04 is set if the absolute value of the post-ramp
speed reference (Pr 2.01) or speed feedback (Pr 3.02) is at or below
minimum speed + 0.5Hz or 5rpm. (Minimum speed is defined by Pr 1.07.)
This parameter is only set if the drive is running.
Below set speed
Pr 10.05 Only set if the drive is running at below set speed. Refer to Pr 3.06, Pr 3.07
and Pr 3.09 in the drive User Guide for more details.
At speed
Pr 10.06 Only set if the drive is running at set speed.
Refer to Pr 3.06, Pr 3.07 and Pr 3.09 in the drive user guide.
Above set speed
Pr 10.07 Only set if the drive is running at above set speed. Refer to Pr 3.06, Pr 3.07
and Pr 3.09 in the drive user guide for more details.
Load reached
Indicates that the modulus of the active current is greater or equal to the
Pr 10.08
rated active current, as defined in menu 4. Refer to the drive Advanced
User Guide for more details.
In current limit
Pr 10.09
Indicates that the current limits are active.
