Step 8B. Connect Brushless Motor For Sinusoidal Commutation (Dmc- 1415 Only) - Galil Motion Control DMC-14 5 Series Manual

Figure 2.5 - System Connections with a separate amplifier (MSA 12-80). This diagram shows the
connections for a standard DC Servo Motor and encoder.

Step 8b. Connect brushless motor for sinusoidal commutation (DMC- 1415 only)

Please consult the factory before operating with sinusoidal commutation. The sinusoidal
commutation option is available only on the DMC-1415. When using sinusoidal commutation, the
parameters for the commutation must be determined and saved in the controllers non-volatile memory.
The servo can then be tuned as described in Step 9.
Step A. Disable the motor amplifier
Step B. Connect the motor amplifier to the controller.

Use the command, MO, to disable the motor amplifiers.
The sinusoidal commutation amplifier requires 2 signals, usually denoted as Phase A &
Phase B. These inputs should be connected to the two sinusoidal signals generated by the
controller. The first signal is the main controller motor output, ACMD. The second
signal utilizes the second DAC on the controller and is brought out on the ICM-1460 at
pin 38 (ACMD2).
