Interface
The Halls Order is obtained as follows:
1. Look at the “Vrs” Output Voltage and determine the Hall Voltage that is lined
up with (or in phase with) this voltage. To determine which Hall Voltage is in
phase with the Vrs Output Voltage draw vertical lines at those points where
it crosses the horizontal line (zero). The dashed lines at the zero crossings
(above) indicate that Hall B output is lined up with (and in phase with) the Vrs
Output Voltage.
2. Look at the “Vst” Output Voltage. Determine which Hall Voltage is in phase
with this Voltage. Per Figure S912, the Hall C output is in phase with the Vst
Output Voltage.
3. Look at the “Vtr” Output Voltage. Determine which Hall Voltage is in phase
with this Voltage. Per Figure S912, the Hall A output is in phase with the Vtr
Output Voltage.
NOTE
If hall sensors are in phase with the corresponding phase voltage
but are inverted 180 degrees (hall sensor waveform edge aligns with
the phase-phase voltage waveform but the positive hall sensor cycle
matches the negative phase-phase waveform or visa-versa), you must
check the “Inverted” check box.
4. The phases that correspond to the Vrs, Vst and Vtr voltages are Hall B then
Hall C then Hall A or Halls number 2 then 3 then 1. Referring to the following
table, we find that 2-3-1 sequence is Halls Order number 3. We would then
enter 3 for the Halls Order field in the motor dialog box.
Hall Order Numbers for Different Hall Sequences
Halls Order Hall Sequence
0 1-2-3
1 1-3-2
2 2-1-3
3 2-3-1
4 3-1-2
5 3-2-1
NOTE
Each Hall Voltage is in phase with one and only one Output Voltage.
B leads A for CW
This is the encoder phase relationship for CW/CCW shaft rotation. When you obtain the
diagram for your motor phasing similar to shown above, it’s assumed by the software
that the motor shaft rotates CW when looking at the mounting face of the motor. For that
rotation Encoder phase A must lead phase B. If it does leave the check box unchecked.
Otherwise (if B leads A), check B leads A in the CW box.
NOTE
Lenze convention references the shaft direction of rotation from the
front (shaft end) of the motor. Some manufacturer’s timing diagrams
are CW when viewed from the “rear” of the motor.
