5.1 - "EXTENDED STAND-ALONE POSITIONER" DESCRIPTION
When the
XtrapulsGem
drive is configured with the
Extended Stand-Alone Positioner
template,
up to 128
control sequences including axis homing, absolute or relative displacement, speed profile running, and torque
regulation can be programmed and combined in order to solve various applications. The sequence chaining
capability allows to define macro-sequences for complex applications: several control sequences can be linked
together in order to be automatically executed one after the other. The control sequences are pre-programmed.
So, the application programming simply consists in initializing the sequence parameters with the desired values.
This drive configuration is suited for stand-alone single-axis control applications.
In the
Extended Stand-Alone Positioner
configuration, the servo drive can be powered or switched off by the
activation or the deactivation of the Enable input.
When the Start input is activated, the selected sequence is started. Then, the other sequences linked with the
starting sequence are automatically executed according to the user programming.
When the Stop input is activated, the program execution is immediately stopped and the motor is maintained
enabled at standstill.
The HOME index input is used for the homing sequence and for the user position reset function.
The RESET input allows to erase any stored drive fault when the cause of the fault release has been cancelled.
The SEQ SEL1 and 2 inputs allow to select the sequence to be started (sequences 0 to 3).
The SEQ COND 1 and 2 inputs allow to control the sequence execution.
The BRAKE output allows to control the motor brake when the drive is enabled and disabled.
The INPOS output is activated when the target position has been reached.
The POWER output is activated when the power supply voltage is applied to the drive.
The SEQ OUT1 output is controlled by the sequence execution.
The block diagram of the “Advanced stand-alone positioner” configuration is presented below.
