Chapter 4 Parameters
4-66
3
Enable (AC motor drive doesn’t run)
Change according to the new
operation command source
4
Disable (AC motor drive will run)
Changes as the external terminal’s
status changes
When the operation command source is from external terminal and operation command is ON
(NPN mode: MI1/MI2-DCM=closed, PNP mode: MI1/MI2+24V=closed, please refer to chapter
2 wiring for details), the AC motor drive will operate according to Pr.02.05 after power is
applied.
<For terminals MI1 and MI2 only>
Setting #4 is an external terminal control setting when the motor drive restarts after an
instantaneous power failure. When the motor drive has an instantaneous power failure, the DC
bus will decrease to LV. If a command is sent from the host computer while the DC bus is at
LV and the operating command is still conductive trigger, the motor drive can be restarted.
1. When Pr.02.05 is set to 0 or 2 or 4, AC motor drive will run immediately.
2. When Pr.02.05 is set to 1 or 3, AC motor drive will remain stopped until operation
command is received after previous operation command is cancelled.
When the operation command source isn’t from the external terminals, independently from
whether the AC motor drive runs or stops, the AC motor drive will operate according to
Pr.02.05 if the two conditions below are both met.
1. When operation command source is changed to external terminal (Pr.02.01=1 or 2)
2.
The status of terminal and AC motor drive is different.
And the operation of the AC motor drive will be:
1. When setting 0 or 1, the status of AC motor drive is not changed by the terminal status.
2. When setting 2 or 3 or 4, the status of AC motor drive is changed by the terminal status.
