(23)CH Control output cycle setting (Un\G47, Un\G79, Un\G111, Un\G143)
CH Heating control output cycle setting (Un\G47, Un\G79, Un\G111, Un\G143)
CH Cooling control output cycle setting (Un\G722, Un\G738, Un\G754,
Un\G770)
Set the pulse cycle (ON/OFF cycle) of the transistor output. In the heating-cooling control, the output cycle of the
heating control and cooling control can be set individually. Additionally, Un\G47, Un\G79, Un\G111, Un\G143 are
used for heating in the heating-cooling control.
The ON time of the control output cycle is determined by multiplying the control output cycle by the
manipulated value (MV)
*1
(%) calculated by PID operation. If the manipulated value (MV)
*1
is constant, a pulse
of the same cycle is output repeatedly.
*1 For the heating control output cycle, the manipulated value for heating (MVh) is used. For the cooling control output
cycle, manipulated value for cooling (MVc) is used.
Ex.
When 700 (70%) is stored in CH Manipulated value (MV) (Un\G13 to Un\G16) and the value of the
buffer memory is set as follows
•CH Control output cycle setting (Un\G47, Un\G79, Un\G111, Un\G143): 100 (100s)
100s × 0.7 (70%) = 70s
The ON time is 70s.
The transistor output turns on for 70s and off for 30s per 100s.
(a) Setting range
The setting range is 1 to 100 (1s to 100s).
(b) Two-position control ( Page 166, Section 4.3 (1))
The setting is invalid.
(c) Default value
The default values are set to 30 (30s) in all channels.
