DRIVE MODULES
The drives that make up Fagor's DDS servo drive system are modular
and stackable. They are connected directly to three-phase mains with a
rated mains voltage between 400-10% and 460+10% V AC at a mains
frequency of 50/60 Hz. Its features are:
supply the motor with a three-phase 400 - 4.5% V AC.
provide the motor with a variable frequency to control its speed and
position.
Hence, we refer to:
Modular drives
AXD Digital module that can govern a synchronous motor in speed and
position working as an axis.
SPD Digital module that can govern a synchronous or an asynchronous
motor in speed and position working as a spindle.
MMC Digital module that can govern a synchronous motor in speed and
position working as an axis or a spindle and also generate a tool
path.
Compact drives
ACD Digital module that can govern a synchronous motor in speed and
position working as an axis.
SCD Digital module that can govern a synchronous or an asynchronous
motor in speed and position working as a spindle.
CMC Digital module that can govern a synchronous motor in speed and
position working as an axis or a spindle and also generate a tool
path.
The drive modules just mentioned can operate with the following motors:
SYNCHRONOUS FXM and FKM families.
ASYNCHRONOUS FM7 and FM9 families.
The following sections analyze all of them showing their technical charac-
teristics and other considerations.
