Specification of high-performance vector convertor
PA-03
Setting range
R Positive effect: When the PID feedback signal is less than a given amount, the inverter output frequency rises. Such as
winding tension control applications.
Reaction: When the PID feedback signal is less than a given amount, the output frequency decreases. As Unwinding tension
control applications. The impact of the multi-function terminal function by PID action direction negated (function 35), the
use of that need attention.
PID given feedback range
PA-04
PID given feedback range is dimensionless units for a given display U0-15 PID and PID feedback display U0-16.
Given relative value of feedback PID 100.0%, corresponding to a given feedback range PA-04. For example if the PA-40 is
set to 2000, then when PID given 100.0%, PID given display U0-15 2000.

Proportional gain Kp 1
Adjusting the intensity of the entire decision PID regulator, Kp1 the greater the greater the intensity. 100.0 This parameter
indicates when the PID feedback value and a given amount of deviation of 100.0% when, PID controller to adjust the
amplitude of the output frequency command is the maximum frequency.
Integration time Ti 1 Determine the intensity of PID regulator integral adjustment. The shorter the integration time
adjustment intensity is. Integration time is when PID feedback quantity and given quantity of deviation of 100.0% of the
time integral regulator continuous adjustment in the amount of the maximum frequency.
Differential time Td 1 PID regulator determines the rate of change of the deviation adjustment strength. Differential longer
adjustment intensity is. Derivative time refers to the amount of change when the feedback 100.0% during that time, to adjust
the amount of the differential regulator for the maximum frequency.
PID reverse cut-off frequency
PA-08
In some cases, only when the PID output frequency is negative (ie, the drive reverse), PID is possible to control the amount
of a given quantity and feedback to the same state, but the high frequency inversion is not allowed on some occasions the,
PA-08 is used to determine the inversion frequency cap.
PA-09
When the PID deviation and feedback value is less than PA-09, PID stops adjustment operation. Thus, given the time and
the feedback output frequency deviation of less stable and unchanging, closed-loop control on some occasions very
effective.
