The analog outputs provide the current (or voltage) by which the module
controls the servo valve. By controlling the servo valve, the module controls
axis motion.
ATTENTION: Applying output to an axis with polarity reversed can
cause sudden high-speed motion. For maximum safety, leave the
analog outputs disconnected and the axis power off until you perform
the axis tuning procedures in Chapter 8.
