4.7. Main Power, Motor Power and Auxiliary Power
The Gold Trombone receives power from main and auxiliary supplies and delivers power to the
motor.
Note:
There are multiple voltage ratings of the Gold Trombone (80 V to 780 V), so you must
use the correct power supply according to the maximum operating voltage of the Gold
Trombone. See Section Chapter 3: Technical Information
4.7.1.

Table 8: Connector for Motor
Connect the M1, M2, M3 and PE pins on the Gold Trombone in the manner described in
Section
4.5 (Integrating the Gold Trombone on a PCB). The phase connection is arbitrary as
Elmo Application Studio (EAS) will establish the proper commutation automatically during
setup. When tuning a number of drives, you can copy the setup file to the other drives and thus
avoid tuning each drive separately. In this case the motor-phase order must be the same as on
the first drive.
