Feedback disconnected detecting value: this detecting value is relative to the full range
(100%). The system detects the PID feedback value all the time. When the feedback value is
less or equal to the feedback disconnected detecting value, the system starts to time the
detection. When the detecting time exceeds the feedback disconnected detecting time, the
system will send an alert of feedback disconnecting failure.
PA. Simple PLC and Multi-Speed Control Group
Simple PLC function is that a programmable logic controller (PLC) which is built-in the
inverter performs the automatic control on the multistage frequency logic. Operation time,
operation direction and operation frequency can be set to meet the process requirements.
This series inverter can perform 16 stages speed variation control with 4 kinds of
Acceleration/Deceleration time available to be choosen.
After the set PLC completes a control loop, an ON signal can be output by multifunction
digital output terminal or by multifunction relay.

0: stop after run once. The inverter automatically stops as soon as it completes one single
loop, and it is needed to send it operating command for it to start again.
1: keep running at the final value after running once. The inverter automatically keeps the
operating frequency and direction after completing one single control loop.
2: Running in cycle. After one loop is finished, the inverter automatically goes to run next
control loop until there is a stop command to stop the system.
