1.2 - DESCRIPTION / COMPLIANCE WITH THE STANDARDS
1.2.1 - General description
The XtrapulsPac drive directly controls the motor torque and speed from of the information provided by a high
resolution position sensor (resolver or encoder). The sinusoidal current commutation generated from the
information of this high resolution position sensor ensures very smooth motor torque/force control.
The XtrapulsPac drive can be configured for the feedback of various position sensor types. The appropriate
position sensor configuration is selectable by software and saved in the drive.
With a resolver sensor feedback, the motor absolute position value over one revolution is available and the
servo motor can immediately be enabled after the drive power up.
With an incremental encoder only, a motor phasing procedure (Phasing) must be executed at each
drive power up before the motor enabling.
With an incremental encoder + Hall Effect Sensors (HES) feedback, the motor phasing procedure is no
more necessary and the servo motor can immediately be enabled after the drive power up.
With an absolute single-turn, multi-turn or linear encoder using the HIPERFACE® communication
protocol and fitted with incremental SinCos outputs, the servo-motor can also be immediately enabled after
the drive powering.
With an absolute single-turn or multi-turn digital encoder using the HIPERFACE DSL® communication
protocol, the servo-motor can also be immediately enabled after the drive powering.
Series XtrapulsPac drives have their own DC/DC converter to provide the voltages required for the drive
operation with a 24 V
DC
+/- 15 % supply source which is generally available on machines. The auxiliary supply
allows keeping the drive logic supplies after the power supply has been switched off. Thus, the position output
can be kept without new initializations of the machine. A 24 V
DC
battery supply with specific wiring allows keeping
the position even after switching off the auxiliary 24 V
DC
supply. This wiring can be used for getting an "absolute"
servo drive operation.
A soft start system limits the inrush current at the mains power on.
All control parameters are programmable via a serial link (e.g. RS-232) and saved in a memory. The auto-tuning
and auto-phasing functions allow a quick and easy commissioning of the drive.
Thanks to the Gem Drive Studio software tool, which is PC compatible with the WINDOWS® operating system, all
drive parameters can be displayed and easily modified.
Gem Drive Studio also allows the quick configuration of the XtrapulsPac drive according to the application type:
as an Analog drive, Stepper motor emulation, Positioner, etc.
The Digital Oscilloscope of this software tool ensures an easy and quick commissioning of the drive.
The Gem Drive Studio software also allows parameterization and diagnostic in a multi-axis configuration.
