Chapter 7 Detailed Explanations of Functional Parameters
0: Do not remember
In the operational process of PLC program, P500 will choose not
to remember. When machinery stops because of fault or other
reasons, inverter will not remember status before the stopping. After
restart, running begins from initial state.
1: Remember
In the running of PLC program, P500 will select to remember. When
it stops because of fault or other reasons, inverter will remember
status before stopping. After restart, inverter will continue operating
according to program. Attention: power cannot be cut off.
Stop,power cut and power on, inverter will not remember status
before power cut off. After restarting, inverter will run according to
initial state of program.

0: Invalid (PLC can not start)
1: Valid (PLC start)
P501 determines PLC start mode of inverter.
P501=0, means PLC is invalid. The inverter is operated by common
mode.
When P501=1, PLC will start. The inverter select PLC program to
run.
Under the status of PLC start, when various running orders and
programs, inverter will choose the highest level to run according to
priority level.
