The meanings of T1~T7 are as follows:
Sign
Meanings
T1
The time is the system delay time from inverter received running
signal to output actuates command of contactor.
T2
The time is the wait delay time from inverter output contactor
actuates command to receive contactor feedback signal.
T3
P8.06(Contacting brake close delay time)
T4
The time is the wait delay time form inverter brake-releasing output
command to receive contracting brake feedback signal.
T5
P8.05(Contacting brake open delay time)
T6
The time is the wait delay time from inverter output closed-brake
command to receive stopping command of external control.
T7
P8.20(Inverter stop delay time)
After inverter receive the running command (FWD) and emergency running
command (EXM), delay the time of T1, the inverter output contactor actuate
control command (TC).
After T2, when the inverter received the feedback signal from contactor, the
inverter is running at 0 speed, and output Y1 at the same time. After T3, the
inverter output contracting brake closing signal (FC).
After T4, the inverter received the feedback signal of contracting brake, after
affirming it is open completely, the inverter is accelerated running with overhaul
run acceleration (P1.17) to reach overhaul running speed(P1.16),and then run at
