Table 9.4 Drive status word bit functions
Bit Parameter Description
0Pr 10.01
bit 0 = 0 :
Drive in stop mode.
bit 0 = 1 :
Drive in ready state.
1Pr 10.02
Drive active
When bit 1 = 1, the drive is in run mode.
2Pr 10.03
Zero speed
Zero speed indicates that the absolute value of the speed reference is at or
below the zero speed threshold defined by Pr 3.05.
3Pr 10.04
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).
In unipolar mode, Pr 10.04 is set if the absolute value of the post-ramp
speed reference (Pr 2.01) is at or below minimum speed (minimum speed
is defined by Pr 1.07.) This parameter is only set if the drive is running.
4Pr 10.05
Below set speed
Only set if the drive is running at below set speed. Refer to Pr 3.06 in the
drive User Guide for more details.
5Pr 10.06
At speed
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.
6Pr 10.07
Above set speed
Only set if the drive is running at above set speed. Refer to Pr 3.06 in the
drive user guide for more details.
7Pr 10.08
Nominal 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 Advanced
User Guide for more details.
8Pr 10.09
Drive out at current limit
Indicates that the current limits are active.
9Pr 10.10
Drive Regenerating
This parameter is set to ENABLED (1) when the power is being transferred
from the motor to the DC Bus.
10 Pr 10.11
Braking IGBT active
Indicates that the braking IGBT is active. If the IGBT becomes active, this
parameter will remain on for at least one second.
11 Pr 10.12
Braking resistor alarm
Dynamic brake alarm is set when the braking IGBT is active, and the
braking energy accumulator is greater than 75%.
12 Pr 10.13
Direction commanded
Direction commanded is set to 1 if the Pre-ramp speed reference (Pr 1.03)
is negative and reset to 0 if the Pre-ramp speed reference is zero or
positive.
13 Pr 10.14
Direction running
A 0 indicates forward direction and a 1 indicates reverse direction. The
source of this bit is Pr 2.01.
14 Pr 10.15
Mains loss
Mains loss indicates that the drive has detected a mains loss from the level
of the DC bus voltage. This parameter can only become active if mains loss
ride through or mains loss stop modes are selected. Refer to Pr 6.03 in the
drive Advanced User Guide for more details.
