4. PARAMETERS
4 - 30
4.3 Software limit
The limit stop with the software limit ([Pr. PT15] to [Pr. PT18]) is the same as the motion of the stroke end.
Exceeding a setting range will stop and servo-lock the shaft. This will be enabled at power-on and will be
disabled in the profile velocity mode, profile torque mode, and homing mode. Setting a same value to
"Software limit +" and "Software limit -" will disable this function. Setting a larger value to "Software limit -"
than "Software limit +" will disable this function.

4.4 How to set the electronic gear
4.4.1 Electronic gear setting for the profile mode
(1) Setting [pulse] with "Position data unit" of [Pr. PT01]
Adjust [Pr. PA06] and [Pr. PA07] to match the servo amplifier setting with the travel distance of the
machine.
