4 AC motor drive runs Changes as the external terminal’s status changes
 Use this parameter to determine whether the AC motor drive receives the operation command or not when the
operation command source is the external terminal, the operation command remains, and the AC motor drive
power is ON.
1. 0: The drive receives the operation command and runs immediately.
2. 1: The drive does not receive the operation command. To make the motor run, cancel the operation
command, and then input again.
3. 4: It 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 decreases to Lv. If you send
a command from the host computer while the DC bus is at Lv, and the operating command is still on
conductive trigger, the motor drive can be restarted.
 Power-on:
When the operation command source is the external terminal and the operation command is ON (MI1-
DCM=closed), the AC motor drive operates according to Pr.02.05 after power is applied.
(1) When you set Pr.02.05 to 0 or 2 or 4, the AC motor drive runs immediately.
(2) When you set Pr.02.05 to 1 or 3, the AC motor drive remains stopped until the operation command is
received after the previous operation command is cancelled.
 When the operation command source is not the external terminals, regardless of whether the AC motor drive
runs or stops, the AC motor drive operates according to Pr.02.05 if the two conditions below are both met.
1. The operation command source is changed to external terminal (Pr.02.01 = 1 or 2)
2. The status of the terminal and the AC motor drive are different.
And the operation of the AC motor drive will be:
1. When you set Pr.02.05 to 0 or 1, the status of the AC motor drive is not changed by the terminal status.
2. When you set Pr.02.05 to 2 or 3 or 4, the status of the AC motor drive is changed by the terminal status.
