AC motors with position sensor (resolver, encoder). The XtrapulsGem drive is a configurable and programmable drive with built-in servo-functions. XtrapulsGem is a single-axis block including power supply unit and mains filters. It is available in both 230 VAC and 400/480 VAC mains operated voltages.
2.1 - "BASIC ANALOG SPEED DRIVE" DESCRIPTION When the XtrapulsGem drive is configured with the Basic Analog Speed Drive template, the motor speed input command is an analog voltage (± 10 V), and the rotor position monitor is available as two channels A and B in quadrature and one marker pulse per revolution (the XtrapulsGem drive must be equipped with the encoder output option board).
Select "Basic Analog Speed Drive" in the Drive Configuration window. 2.4 - "BASIC ANALOG SPEED DRIVE" COMMISSIONING Setup the motor parameters in the Motor Configuration window (see XtrapulsGem User guide) Setup the user position scaling, in the Position sensors window, in order to get the axis position and speed displayed in the application unit according to the mechanical load (not mandatory for a speed drive).

Setup the Stop operation parameters, the Brake control parameters and the Analog output signal if required. Setup the servo loop gains by using the Autotuning procedure (see XtrapulsGem User guide) Enable the drive and check the motor stability at standstill and in rotation by using the Manual Jog operation.
3.1 - "ADVANCED ANALOG SPEED DRIVE" DESCRIPTION When the XtrapulsGem drive is configured with the Advanced Analog Speed Drive template, the motor speed input command is an analog voltage (± 10 V), and the rotor position monitor is available as two channels A and B in quadrature and one marker pulse per revolution (XtrapulsGem drive must be equipped with the encoder output option board).

XtrapulsGem Application Templates The SPEED MODULATION analog input (0 to 10 V) allows to reduce on-the-fly the sequence speed value proportionally to the applied input voltage. The CURRENT LIMIT analog input (0 to 10 V) allows to limit the motor peak current proportionally to the applied input voltage.
Setup the user position scaling, in the Position sensors window, in order to get the axis position and speed displayed in the application unit according to the mechanical load (see XtrapulsGem User guide). Setup the manual movement parameter values in the Manual mode window. Enter first a low value for the Profile Velocity parameter.
