No signal loss detection is possible while an input is in bipolar voltage mode. The
signal loss condition will never occur even if signal loss detection is enabled.

Trim
An analog input can be used to trim the active speed reference (Speed Reference
A/B). If analog is chosen as a trim input, two scale parameters are provide to scale
the trim reference. The trim is a +/- value which is summed with the current
speed reference. See also Speed Reference on page
• [Trim In Select]
• [Trim Out Select]
• [Trim Hi]
• [Trim Lo]
Value Display
Parameters are available in the Monitoring Group to view the actual value of an
analog input regardless of its use in the application. Whether it is a current limit
adjustment, speed reference or trim function, the incoming value can be read via
these parameters.
The value displayed includes the input value plus any factory hardware
calibration value, but does not include scaling information programmed by the
user (i.e. [Analog In 1 Hi/Lo]). The units displayed are determined by the
associated configuration bit (Volts or mA)
