(d) The following lists the setting ranges.
The default value is the upper limit of the input range.
• Zone 1 upper limit: Lower limit of the input range to upper limit of the input
range
• Zone 2 upper limit: Zone 1 upper limit to upper limit of the input range
• Zone 3 upper limit: Zone 2 upper limit to upper limit of the input range
• Zone 4 upper limit: Zone 3 upper limit to upper limit of the input range
• Zone 5 upper limit: Zone 4 upper limit to upper limit of the input range
• Zone 6 upper limit: Zone 5 upper limit to upper limit of the input range
• Zone 7 upper limit: Zone 6 upper limit to upper limit of the input range
Make the setting in the order of the zone 1
allocating from the lower limit of the input range.
(Example) Thermocouple input
POINT
• To divide a zone into four, set the upper limit values for the zone 1 to 3, and set
the upper limit value of the input range (default) for the zone 4 to 7.
• Upper/lower setting limiter (buffer memory address: 55, 56, 87, 88) does not give
any restriction on setting values in Zone 1 to 7 upper limit. Note, however, that a
write error occurs if a value out of the range is set. Then Error flag (Xn2) turns on
and the error code 4 is stored to Error code (buffer memory address: 0).
(2) Zone 1 to 8 PID constant setting
(a) The PID constants of proportional band (P), integral time (I), and derivative
time (D) corresponding to each zone are set.
(b) For details of the setting range, refer to Section 3.5.14.
(3) Zone 1 to 8 PID control response parameters
(a) The control response parameters corresponding to each zone are set.
(b) For details of the setting value, refer to Section 3.5.22.
