ADDITIONAL CONTROL I/O
1. Inputs
ZERO
Bit
Bit
2. Outputs
RES Bit
If
ZERO
bit is low, OUT = 0. When
ZERO
bit goes high, OUT ramps to REF by the
UP or DWN ramp rates in addition to the RND input.
If the RES bit is high, OUT = REF. (Second in priority)
If the
bit is low, OUT is held at its present value. The rounding continues to
prevent a step response. When HLD goes high, OUT ramps to REF by the appropriate
rate.
The following figures 4-61C, 4-61D, and 4-61E graphically represent various RMP2
Control block input results.
