4. Parameter description
Parameter
<Setting>
• When P.170 = 0, PID is forbidden.
• When P.170 = 1, the feedback value is setting by voltage which from terminal 2-5.
• When P.170 = 2, the feedback value is setting by current which from terminal 4-5.
• PID gain easy setting:
(1).Using pure proportional control, increasing PID proportion Gain progressively, the system to gain
critical concussion.
(2).Adjusting the 80 % PID proportion Gain witch setting in (1), increasing PID integration Gain
progressively, until we have the satisfactory movement performance.
(3).To keep PID integration Gain, adjusting PID proportion Gain and observe control process
improvement, if there is any improvement continued until satisfaction. If not, increasing
originally PID proportion Gain, then adjust PID integration Gain to improve control process. So
repeatedly, until find a satisfactory together the PID proportion Gain and PID integration Gain.
(4).Control process do not use PID differential Gain generally, when use PID differential Gain we
can adjust PID proportion Gain and PID integration Gain properly. And the same steps,
differential time setting repeatedly, until find a satisfactory control process.
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 is setting by current 4-5, this function will be useless.
