DRIVES
The AXD/SPD and ACD/SCD drives that make up FAGOR's DDS system
are modular and stackable. They are connected directly to three-phase
mains with a line voltage between 400 (1-10 %) V AC and 460 (1+10 %) V
AC at a line frequency between 48 ... 62 Hz. Its features are:
supply the motor with a three-phase 400 (1- 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 drives just mentioned can operate with the following motors:
SYNCHRONOUS FXM|FKM
ASYNCHRONOUS FM7|FM9
The following sections analyze all of them showing their technical
characteristics and other considerations.
NOTE. Keep in mind that FAGOR also has ACD/SCD-...- L compact
drives to be connected to a three-phase mains with a line voltage of
between 200 (1-10 %) V AC and 240 (1+10 %) V AC and line frequency
of between 48 ... 62 Hz.
