when the actual accumulative power-on time reaches the threshold of 100 hours, perform the setting as
follows:
1) Set virtual X1 to user-defined fault 1: A1-00 = 44.
2) Set that the valid state of virtual X1 is from virtual DO1: A1-05 = 0000.
3) Set virtual DO1 to power-on time reached: A1-11= 24.
4) Set the accumulative power-on time threshold to 100 h: P8-16 = 100 h.
Then, the AC drive reports Err27 when the accumulative power-on time reaches 100 hours.

It is used to set the accumulative running time threshold of the AC drive. If the accumulative running time
(P7-09) reaches the value set in this parameter, the corresponding DO terminal becomes ON.

This parameter is used to set whether to enable the safety protection. If it is set to 1, the AC drive does not
respond to the run command valid upon AC drive power-on (for example, an input terminal is ON before
power-on). The AC drive responds only after the run command is cancelled and becomes valid again.
In addition, the AC drive does not respond to the run command valid upon fault reset of the AC drive. The run
protection can be disabled only after the run command is cancelled.
In this way, the motor can be protected from responding to run commands upon power-on or fault reset in
unexpected conditions.

If the running frequency is higher than the value of P8-19, the corresponding DO terminal becomes ON. If the
running frequency is lower than value of P8-19, the DO terminal goes OFF
These two parameters are respectively used to set the detection value of output frequency and hysteresis
value upon cancellation of the output. The value of P8-20 is a percentage of the hysteresis frequency to the
frequency detection value (P8-19).
