Program description：
When PLC changes from STOP to RUN, M8002 coil gets through a scan cycle, set high
ncy t ed-down time into D220, set M0,
tor uency and work 3 rounds, set coil M8170 at the same
time; the motor runs 3 rounds, the speed-down till stop, coil M8170 reset. Here reset M0, set
M1, revers quency parameters into D200、D210. the counter starts to
delay with 2 seconds, when reach this 2 seconds, M1 is reset, M0 is set again, the motor starts to
run 1 round with low frequency. After finish this 1 round, the motor starts to run with high
again! In this format, the motor runs with high frequency and low frequency.
