SixStep SFD, 6-Step
This variable indicates whether the drive is in 6-step or sinusoidal current control.
SWEnable Disable, Enable
Serial communications channel motor power enable. Both the hardware enable input on the
command I/O connector and SWEnable must be active for power to flow to the motor. Base
units have SWEnable active at power up. This variable is provided for convenience when
working with a PC set utility.
0 - Disables drive.
1 - Enable set by state of hardware enable input (default).
VBus 0 to 523 volts : AC Input Drives
0 to 131 volts : DC Input Drives
This variable reads back an instantaneous sample of the voltage of the bus supplying power to
the motor.
VelFB –18,310 rpm to +18,310 rpm
This variable reads back an instantaneous sample of the shaft velocity feedback. It has a
resolution of 0.5588 rpm. When measuring speed, use Velocity for least noise and maximum
accuracy.
Velocity –18,310 rpm to +18,310 rpm
This variable reads back a filtered version of the shaft velocity feedback. It has the same units
as VelFB, but it is much more precise for careful measurements of shaft speed because the
filtering greatly lowers noise. To implement the filtered velocity value the drive subtracts two
consecutive PosFB values sampled at a 26.21 mSec sample period which corresponds to a
38.15 Hz sample rate. This filter is equivalent to adding 512 consecutive samples of VelFB and
dividing by 512.
VerLW 0.0a to 255.9z
VerLW gives the version number of the drives logicware as three integer bytes.
This manual documents VerLW 3.0A and newer.
