ACSD-60/80 Digital Brushless AC Servo Drive system - Ref.1609
N. Linear axis configuration
Function Parameter that shows the relationship between the load
inertia and that of the motor rotor. When calculating this
ratio, bear in mind the mechanical transmission ratio
between the load movement and the motor rotation.
Valid values 0.00 ... 1 000.00 %.
Default value 0.00 %.
Function Parameter that cannot be modified by the user that “tells”
the CNC the number of pulses of the motor feedback.
Valid values 0 ... 65 535 pulses.
Default value It depends on the motor connected.
Function They define the gear ratio between the motor shaft and the
final axis moved by the machine. For example, if 5 turns of
the motor shaft mean 3 turns of the machine leadscrew, the
value of these parameters is NP121=5, NP122=3.
Valid values 1 ... 65 535 turns.
Default value 1 turn in both parameters (direct coupling).
Function It defines the gear ratio between the linear movement of the
machine and the axis moving it. For example, if every turn of
the leadscrew means a 4 mm displacement of the table, the
value for this parameter is NP123=4. If it is a rotary axis, set
NP123 = 360 (360º per turn).
Valid values 0 ... 214 748 mm.
Default value 5 000 µm (5mm per turn).
