7. FUNCTIONS

IMSRM02-E6

(9) Balanceless/bumpless

This function is used to prevent overload caused by the manipulated output value (MV) suddenly
changing when auto mode is transferred to manual mode and vice versa.

Operation during transfer from auto mode to manual mode

When the mode is transferred to manual mode the manipulated output value (MV) follows that in auto
mode.

Operation during transfer from manual mode to auto mode

When manual mode is transferred to auto mode, the manipulated output changes to that calculated
with respect to the set value.

Manipulated output

Auto mode

Manual mode

Time

(a)

(b)

(c)

(a) Transfer from auto mode to manual mode. However, when the mode is transferred to manual

mode, the manipulated output follows that in auto mode.

(b) The manipulated output changed (manual mode function).
(c) Transfer from manual mode to auto mode. When the mode is transferred to auto mode, the

manipulated output becomes that calculated with respect to the set value.
