DMC-1400 Series Command Reference BS ● 45
BS
FUNCTION: Brushless Setup
DESCRIPTION:
The command BS tests the wiring of a sinusoidally commutated brushless motor. If no Hall
sensors are connected, the function tests the wiring of the DAC's. If Hall sensors are
connected, the function also tests the wiring of the Hall sensors. The first parameter
indicates the voltage level to be applied to each phase, and the second parameter indicates
the duration in milliseconds that the voltage will be applied.
This command returns status information regarding the setup of brushless motors. The
following information will be returned by the controller:
1. Correct wiring of the brushless motor phases.
2. An approximate value of the motor's magnetic cycle.
3. The value of the BB command (If hall sensors are used).
4. The results of the hall sensor wiring test (If hall sensors are used).
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: BSX= V, n or BS V, n where
V is a real number between 0 and 10, and n is a positive integer between 100 or 1000.
