It assigns one M (Monitoring) or C (Control) code to the
Analog Output signal. That variable will be routed (via
firmware) to the digital-to-analog converter DAC and
will thus show up on the Analog Output pins.
These are positive and negative offset numbers for
primary and secondary data sets. These allow the
feedback to contain a bias. Only one (positive or
negative) number can be non-zero at any given time.
It dictates the operation of Zero-speed alarm output. If
set to 0, the output is controlled only by the ramped
reference (M-46); if set to 1, the output is controlled by
both the ramped reference (M-46) and the feedback (M-
43).
In other words,
If C74 = 0, ZERO SPEED output is HIGH whenever
Ramped Reference (instantaneous desired speed) is
zero and the output is LOW at all other times.
IF C74 = 1, ZERO SPEED output is LOW whenever
Ramped Reference is non-zero, but does not go HIGH
until both Ramped Reference and Feedback are BOTH
zero.
It determines which setpoints are disabled when keypad
is locked out (J4, pins 1 and 2 shorted).
