Output Channel
The servo amp has one monitor output channel for servo adjustment pur-
poses.
This output is provided via a special connector at the top of the
amp's front panel.
D/A output specifications are as follows:

The output voltage is determined according to the formula below. To alter
the output voltage,
adjust the output amplification rate. Note that if
SV063
is zero,
the output is determined on the assumption that this
parameter is set to 256.

With settings of SV061 0 and SV063 = 8 and a motor
speed of 3,000 rpm,
