PVD 3530 GB 01/2005
1.3.2 Power supply functions
Receives the 230 V mains supply through terminal block B3 and converts it into a 325V dc
voltage.
Receives the 230V monophase mains supply through the same B3 terminal block for powering
the auxiliary power supplies (+/-15V, 5V) required by safety regulations.
May receive a 24 V supply via terminal block B1 for powering the motor brake.
1.3.3 Servomotor control functions
1.3.3.1 Presentation
The DIGIVEX Little Drive (DLD) servo-amplifier is a 4-quadrant, transistor control module for
controlling (brushless) synchronous motors with resolvers.
NX, LX, LS, LD spindle drive motors. See separate documentation (PVD3407 and PVD3535).
The customization of the motor - resolver unit and the setting of the servocontrol parameters are
carried out using a PC with DIGIVEX software (PME software, DIGIVEX module), under
Windows.
These parameters are stored in an EEPROM permanent memory.
