Setting content Initial value
38 MV2 MLL 2 to MLH 2 (%) 0.0
The screen is for displaying the operating amount for the secndary control.
The operating amount cannot be set for the normal control.
The operating amount can be set only when the control mode is set to manual.
■ Secondary control output gain setting

Setting content Initial value
39 MV2G 0.0 to 1000.0 (%) 100.0
The operating amount (MV 1) for the secondary control is multiplied by a compensation value.
[Operating amount for the secondary control] = [Operating amount for the secondary control before compensation] ×
[Secondary control output gain setting]
■ Secondary control proportional band setting
SEt04
CNt
Setting content Initial value
40 P2 0.10 to 10.00 (times) 1.00
Set the secondary control proportional band.
The proportional band of the secondary control is set in a multiplication factor of 0.1 to 10 with respect to the proportional
band of the primary control.
The proportional band of the secondary control is always set in opposite side to the proportional band of the primary control
about SV.
Setting example: Where the proportional band range P2 of the secondary control is set to 2.00, P2 is twice as large as the
proportional band range P1 of the primary control.

When P2 = 2.00 is set, the proportional
band range of the secondary control is
twice as large as that of the primary
control.
