Setting method (dividing channels into groups)
Configure the setting as follows:
[Navigation window]  [Parameter]  Target module  [Application Setting]  [Simultaneous temperature rise setting]
 [Simultaneous temperature rise group setting]
Simultaneous temperature rise parameter
The simultaneous temperature rise parameter is the values in the following two buffer memory areas:
• 'CH1 Simultaneous temperature rise gradient data' (Un\G554)
• 'CH1 Simultaneous temperature rise dead time' (Un\G555)
■Automatic calculation
The simultaneous temperature rise parameter can be automatically calculated using the following two methods:
• Simultaneous temperature rise AT
• Simultaneous temperature rise parameter setting with self-tuning
When the setting of "Peak current suppression control group setting" of "Peak current suppression setting" in
"Application Setting" is changed after the simultaneous temperature rise parameter has been calculated, the
intended control may not be executed. In that case, calculate the simultaneous temperature rise parameter
again. For details on the peak current suppression function, refer to the following:
Page 95 Peak Current Suppression Function
Simultaneous temperature rise AT
PID constants and the simultaneous temperature rise parameter are calculated. The waveform upon execution is the same as
that for the auto tuning function.
For details on the auto tuning function, refer to the following:
Page 38 Auto Tuning Function
■Procedure for executing the simultaneous temperature rise AT
The following shows the procedure for executing simultaneous temperature rise AT.
1.
Set "AT for Simultaneous Temperature Rise" for "Simultaneous temperature rise AT mode setting."
[Navigation window]  [Parameter]  Target module  [Application Setting]  [Simultaneous temperature rise setting]
 [Simultaneous temperature rise AT mode setting]
2.
Turn from OFF to ON 'CH1 Auto tuning command' (Y4).
3.
Shift the mode to the operation mode (turn from OFF to ON 'Setting/operation mode command' (Y1).
