To operate the P series drives at low DC voltages, in the Drive Support Tool software, hold the Alt key and then click the Engineering Setup (blue down arrow icon in toolbar).
This will open a window allowing users to click a check box for DC input:
This allows the standard drive to operate at 24, 48 or 80volts for the new mSR080 miniature square rail linear servo positioner or other low voltage motors.
Then click the Flash Save button (EEPROM icon).
DO NOT apply AC voltage to the drives mains connections L1, L2, L3
