Creating Custom Motor Files D-5
Encoder Sequencing
Separate from the phasing of the commutation and motor power
signals, the encoder A quad B signals must sequence properly. The A
channel must lead the B channel for CW motion when viewed looking
at the motor shaft from the load. Figure D.3 depicts this encoder
signal sequencing. If the encoder phasing is not as shown in
Figure D.3, the encoder leads must be swapped.
Motor Parameter Definitions
The parameters to configure in a custom motor file are defined below.
ULTRA Master arranges motor parameters in an index card format.
The groupings are:
●
General,
●
Feedback,
● Current Loop,
●
Electrical, and
●
Ratings.
General Parameters
Motor Model
The motor model field is a text display from which a motor is selected.
If the motor model text string is changed, ULTRA Master assumes
that a new motor file is being created, and the user must supply a new
filename. This prevents the text string being changed on an existing
motor file. However, a filename may be recycled by:
1. Assign the new file a tentative filename.
2. Delete the old file.
3. Rename the new file, using the old filename.
