DMC-21x3 Accessories Appendix C Command Reference• 109
BS
FUNCTION:
Brushless Setup
DESCRIPTION:
The command BS tests the wiring of a brushless motor. If Hall sensors are connected,
this command also tests the wiring of the Hall sensors. This function can only be
performed with one axis at a time.
This command returns status information regarding the setup of brushless motors. The
following information will be returned by the controller:
1. The results of the hall sensor wiring test (If hall sensors are used).
2. Correct wiring of the brushless motor phases or how to change direction.
This command will turn the motor off when done and may be given when the motor is
off.
Once the brushless motor is properly setup and the motor configuration has been saved in
non-volatile memory, the BS command does not have to be re-issued. The
configuration is saved by using the burn command, BN.
Note:
In order to properly conduct the brushless setup, the motor must be allowed to
move a minimum of one magnetic cycle in both directions.
ARGUMENTS:
BSA= v, n where
v is a real number between 0 and 10. v represents the voltage level to be applied to each
phase.
n is a positive integer between 100 or 1000. n represents the duration in milliseconds that
voltage should be applied to the motor phases.
USAGE: DEFAULTS:
While Moving No Default Value of n 0
In a Program Yes Default Value of n 200
Command Line Yes
Controller Usage
ALL CONTROLLERS / DMC 21x3 with AMP-205xx
EXAMPLES:
BSC = 2,900 Apply set up test to C axis with 2 volts for 900 millisecond on each step.
Note 1: When using Galil Windows software, the timeout must be set to a minimum of 10 seconds
(timeout = 10000) when executing the BS command. This allows the software to retrieve all
messages returned from the controller.
Note 2: For a DMC-21x3 with an attached AMP-205x0, the BS command performs an algorithm
that verifies the correct motor phase wiring. If incorrect, the command will recommend the
correct motor phase wiring.
Example: BSY=
: Wire A to terminal B, wire B to terminal A
