Chapter 4: Communication-Based Operation
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.)
■ Gland packing type
For the hysteresis difference due to friction of the control valve gland packing,
select from [Heavy], [Medium] and [Light]. (This is selected automatically when auto-
setup is executed.) Regarding the types of gland packing, see Table 2 below.
Table 2. Gland Packing Type Parameter Table
Hysteresis* (HYSTERESIS) Gland packing material example
Heavy (HEAVY) Graphite packing
Medium (MEDIUM) Yarn packing
Light (LIGHT) V type PTFE packing
* This cannot be decided on the basis of material because it depends on the
frictional force of the gland packing.
