(5) Output Signal Low Cut Mode Setup
(D10: LOW CUT, D11: LOW CUT MODE)
Low cut mode can be used to stabilize the output

in a range from 0 to 20% of output. (Hysteresis:
±
1%)
Either “ LINEAR ” or “ ZERO ” can be selected as the
low cut mode.

(6) Change Output Limits
(D15: OUT LIMIT(L), D16: OUT LIMIT(H))
The range of normal output is preset at the factory
from –5.0% to 110.0% unless otherwise specified or
conditioned, and the output is limited with these upper
and lower values. This output range can be changed,
for example, to meet the requirements of NAMUR,
within the settable range. Set the lower limit with
D15: OUT LIMIT(L) and upper limit with D16: OUT
LIMIT(H).
Settable range : –5.0 to 110.0 (%)
