XtrapulsPac pac-et 230/11 sinusoidal synchronous AC motors

XtrapulsPac all-digital drives with sinusoidal PWM control are servo drives that provide the control of brushless
AC motors with a position sensor.
The standard control interface can be:
– CANopen,
– EtherCAT®1,
– analog,
– stepper motor emulation,
– logic I/Os.
But the XtrapulsPac range also offers more sophisticated functions such as:
– DS402 including position capture,
– Master/slave and electronic gearing,
– Positioner with motion sequencing.
All versions are delivered in standard with the integrated safety function Safe Torque Off (STO) SIL 2.
With its very small dimensions, the XtrapulsPac is available in various designs:
– stand-alone or multi-axis version,
– standard forced air or push-through cooling version.
Series XtrapulsPac drives are fully configurable in order to fit various applications. Both drive versions of the XtrapulsPac range are described below.
The XtrapulsPac version with CANopen interface can be used in the following application types:
Axes controlled by CANopen fieldbus according to the DS402 protocol,
Stand-alone operation as a motion sequencer with control by means of logic I/Os,
Traditional analog speed drive with +/- 10 V command and position output by A, B, Z encoder signal emulation,
Stepper motor emulation with PULSE and DIR command signals.
The XtrapulsPac version with EtherCAT® interface can be used in the following application types:
Axes controlled by EtherCAT® fieldbus according to the DS402 protocol,
Stand-alone operation as a motion sequencer with control by means of logic I/Os.
The configuration and parameterization software tool Gem Drive Studio allows a quick configuration of the XtrapulsPac drives according to the target application (template).

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.
an incremental encoder only, a motor phasing procedure (Phasing) must be executed at each
drive power up before the motor enabling.
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.
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.
