Table 6-1 shows the drive’s action under different
conditions. ―0‖ means the drive enter ready status and
―1‖ means the drive start operation automatically.
Note:
1.When using the panel or serial port or 3-wire mode 1
and 2 to start or stop the drive, the command signal is in
pulse mode and there is no operating command when the
drive is switched on.
2.If there is a stopping command, the drive will stop
first. 3.When the function of restart after power failure is
enabled, the drive will start on the fly after power on if it
is not switched off totally (that is, the motor still runs
and drive’s LED displays ―P.OFF‖). It will start in the
starting mode defined in A1.00 after power on if it is
switched off totally (LED turns off).
