3.4 Buffer Memory Assignment
3.4.2 Details of the buffer memory
This area is enabled only for the following channels.
• CH1 to CH4 when the standard control is used
• CH3 and CH4 when mix control (normal mode) or mix control (expanded mode) is used
Set content in CH Self-
tuning setting (Un\G574,
Un\G606, Un\G638, Un\G670)
Check description
1: Starting ST (PID constants only)
• Check the control loop for wiring problems.
• Switch CH Self-tuning setting (Un\G574, Un\G606, Un\G638, Un\G670) to "4:
Starting ST plus vibration ST (PID constants only)" to perform control.
3: Starting ST (PID constants and
simultaneous temperature rise
parameter)
• Check the control loop for wiring problems.
• Save the calculated simultaneous temperature rise parameter, if any. Then, switch
CH Self-tuning setting (Un\G574, Un\G606, Un\G638, Un\G670) to "4: Starting
ST plus vibration ST (PID constants only)" to perform control. If no simultaneous
temperature rise parameter is calculated, check the control loop for wiring
problems.
