Operation & Software Manual
Direct Drives & Systems 51
8.3.6 Mass or inertia
The controller needs the mass (linear system) or the inertia (rotary system) value to correctly set up its
regulator. The whole moving mass should be included in this value (not only the motor). Take the mechanical
frictions into account to give accurate values to the controller! With a wrong value your system will not work
correctly!
• Click in the dedicated field and enter the value (here: 500.00 E -3 [kg], we have a linear system)
• Click on the NEXT button, wait a few seconds until the next window appears.
8.3.7 Automatic tuning options
These options are displayed for your information only (CURRENT LOOP ADJUSTMENT, MOTOR PHASES RESEARCH,
FINE PHASE ADJUSTMENT), leave them set by default, unless you are an expert.
Note:The Current loop adjustment button is deactivated only when an ironless motor is used (low
inductance).
• Do not click on the advanced button unless you are an experienced user!.
• Put the motor in the middle of the stroke to avoid problems and click on START. The message Automatic
tuning proceeding! appears. Wait until the next window appears (in case of problem, click on Abort).
