GE DS200SNPAH1A Gas turbine communication card

Isolation of control circuits–Maestro range of servo drives The control circuits of these drives are not isolated from the power circuits. In most applications an isolating transformer is used to supply the drive, and the negative terminal of the drive DC power circuit is connected to ground. Provided that the ground connection is adequate to carry the prospective fault current of the supply, the control circuits may safely be connected to other grounded circuits. If the negative DC terminal is not connected to ground then the control circuits must be treated as live at the AC supply potential.

Braking resistor data

External Braking resistor When a Maxi-Maestro drive is used, due to the fact that there is no internal braking resistor, an external braking resistor is required. The braking resistor defined as follows is supplied with the drive The minimum resistor value has been set to limit the current, through the braking circuit, to protect the drive if a larger rated external braking resistor is required.Potentiometers, mounted components and switches fitted on a daughter board are used to configure the drive. If there is a need to replace the drive, and the configuration is required in the replacement, the daughter board can be removed and installed in the replacement drive
