4-4-4. Control configuration
For the device’s dynamic characteristics, the PID parameters are selected based on the
combination of actuator size and gland packing type.
Actuator size
Select the actuator size from parameters 0 to 9, A, B, and C (Param 0 to 9, A, B, and C).
(This is selected automatically when auto-setup is executed.)
If auto setup cannot be executed or the desired parameter cannot be set by auto setup, see the
table below to select a PARAM that is suitable for the installed actuator.

Actuator size configuration procedure
step Procedure
1
Select [Device] >> [Setup] >> [Control Configuration] >> [Act. Size/Gland
Packing Type], and check the current setting.
2
Select [Device] >> [Setup] >> [Control Configuration] >> [Change Actuator
Size], and select from parameters 0 to 9, A, B, and C. If parameter 0 has been
selected, the gap action type PID parameters can be set individually. (Parameters
7 to 9 are specifically for the Azbil Corporation VFR control valve RSA/VR
actuator.)
