4. Parameter description
Parameter
<Setting>
• PID gain easy setting:
(1)After changing target, response is slow
---Increase P-gain (K
P
=P.172)
response is quick but unstable
---Decrease P-gain (K
P
=P.172)
When
K
P
is too small
When
K
P
is too large
When
K
P
is appropriate
(2)Target and feedback
do not become equal
---Decrease Integration time (K
I
=P.173)
become equal after unstable vibration
---Increase Integration time (K
I
=P.173)
When K
I
is appropriate
When K
I
is too short
When K
I
is too long
(3)Even after increasing K
P
, response is still slow
---Increase D-gain (K
D
=P.174)
It is still unstable
---Decrease D-gain (K
D
=P.174)
Note: If P.187=1, P.181 and P.182 are in the range of 0~1000Hz, P.183 is in the range of 0~100Hz.

<Setting>
• When P.184 = 0, this function is useless, if the terminal 4-5 is disconnected, the inverter will slow
down to 0Hz.
• When P.184 =1, if the terminal 4-5 is disconnected, the keyboard panel should be shown “AErr”,
the inverter will
slow down to 0Hz. If connected the terminal 4-5 again, the alarm code will disappear, the
inverter will be accelerated to the current corresponding to the frequency.
• When P.184 = 2, if the terminal 4-5 is disconnected, the keyboard panel should be shown “AErr”,
the inverter Immediately stop and needs to be reset.
• When P.184 = 3, if the terminal 4-5 is disconnected, the keyboard panel should be shown “AErr”,
the frequency which is before disconnect of
the inverter is
continuing operation, reconnect the line, the alarm
disappears.
Note: When P.17=1, the terminal 4-5 is setting by current 4-5, this function will be useless.
