(2) Cascade control and control mode
The cascade control function can only be used with the combination of the
following three control modes.
When the control modes are combined with other ones in the following table,
the cascade control is not performed even if the cascade ON/OFF (buffer
memory address: 176) is set to 1(ON).
When control modes are combined with other control modes than the following
three, each channel operates individually.
No.

*1: When the program control is reset, each cascade control cannot be
performed.
(3) Execution of cascade control
The execution of cascade control is performed by the following procedure.
During the cascade control, the cascade signal is monitored on the cascade
monitor (buffer memory address: 179).
Set each of the data of
Q62HLC.
Switch control mode and start
control.
Perform cascade control.
POINT
• Auto tuning cannot be executed during cascade control. To execute auto tuning,
set the cascade ON/OFF (buffer memory address: 176) to "0" (OFF). To check
that the cascade control is stopped, confirm that "0" is stored in the cascade
monitor (buffer memory address: 179).
• Auto tuning can be executed on the slave channel only.

Set the necessary data and others for the control
of each control mode, cascade gain (buffer memory
address: 177), and cascade bias (buffer memory
address: 178).
Set the control mode (buffer memory address: 50, 82).
Confirm the corresponding channel on the control mode
monitor (buffer memory address: 30).
Turn on the setting/operation mode command (Yn1).
Confirm the setting/operation mode command (Xn1) is turned on.
