Servo Parameters
Chapter 7
7-96
Notes
This parameter must be set independently for each servo.
Examples:
Using a non-digital servo amplifier for the motor connected to the
DAC output (typically the spindle): Use a
Using the 3-axis servo amplifier with all axes on that amplifier
positioned by the same servo module and connecting this axis to
CNA2 on the amplifier : Use c
Using the 2-axis servo amplifier with all axes on that amplifier
positioned by the same servo module and connecting this axis to
CNA1 on the amplifier: Use e
Using the 1-axis servo amplifier with its axis positioned by either
servo module and connecting this axis to CNA1 on the amplifier:
Use g
Using the 3-axis servo amplifier with two servo modules and
connecting this axis to CNA1, CNA2 or CNA3 on the amplifier:
Use h
Using the 2-axis servo amplifier with two servo modules and
connecting this axis to CNA1 or CNA2 on the amplifier: Use i
Using only two axes on the 3-axis servo amplifier with both axes on
that amplifier positioned by the same servo module and connecting
this axis to CNA1 on the amplifier: Use j
Using only one axis on the 3-axis servo amplifier, positioned by
either servo module and connecting this axis to CNA1, CNA2, or
CNA3 on the amplifier: Use l
Using only one axis on the 2-axis servo amplifier, positioned by
either servo module and connecting this axis to CNA1 or CNA2 on
the amplifier: Use m
