CH1 Control output cycle setting
Set the pulse cycle (ON/OFF cycle) of the transistor output.
OFF
Transistor output
The ON time of the control output cycle is determined by multiplying the control output cycle by the manipulated value (MV)
(%) calculated by a PID operation. When the manipulated value (MV) is stable, pulses are repeatedly output in the same
cycle.
Ex.
When 700 (70%) has been stored in 'CH1 Manipulated value (MV)' (Un\G403) and the value in the following buffer memory
area has been set as follows:
• 'CH1 Control output cycle setting' (Un\G504): 100 (100s)
100s  0.7 (70%) = 70s
The ON time is 70s. The transistor output is ON for 70s and OFF for 30s per 100s.
