K2VC (#4) 1: The function for changing the proportional gain in the stop state is
used.

− −
Function for changing the proportional gain in the stop state: Stop
judgement level
[Increment system] Detection unit
[Valid data range] 2 to 10
When the absolute value of an error is lower than the stop judgement
level, the function changes the proportional gain of the velocity loop
(PK2V) to 75% or 50% of the set value.
If the machine vibrates while in the stop state, enable this function and
set a value greater than the absolute value of the error causing the
vibration as the stop judgement level. The function cannot stop the
vibration of a machine in the stop state when the current velocity loop
proportional gain is too high. Should this occur, reduce the velocity
loop proportional gain.
Fig. 4.4.3 Relationship between error and velocity loop proportional gain
(PK2V)
NOTE
When the velocity loop high cycle management
function (⇒ Subsec. 4.4.2) is used, this function is
disabled for all servo software series/editions except
some series/editions.
(With Series 9080/U(21) and subsequent editions and
Series 90A0/D(04) and subsequent editions, this
function can be used together with the velocity loop
high cycle management function.)
