2 When the source of the command changes, VFD’s operation remains the same.
3 When the source of the command changes, VFD’s operation follows the new
command.
4
The motor drive can start to run at power on or after reset.
When the source of command is a 2-wire external terminal, the operating
command changes as the external terminal’s status changes.
This parameter determines the response of the drive upon power on and operation command source is
changed.
Pr.02.05

changed
0 Disable (AC motor drive will run) Keep previous status
1 Enable (AC motor drive doesn’t run) Keep previous status
2 Disable (AC motor drive will run)
Change according to the new operation command

When the operation command source is from external terminal and operation command is ON (MI1/MI2-
DCM=closed), 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.
