Motor Stopping and Restarting Methods
There are two ways to stop and restart the motor.
 Method 1
To stop the motor, set bit 0 (Forward RUN) and bit 1 (Reserve RUN) of Input Command
(OW10) to 0 (OFF) while the Inverter Drive Control command is being executed in Com-
mand (OW08).
To restart the motor, set bit 0 or bit 1 of OW10 to 1 (ON).
 Method 2
To stop the motor, set bit D (Drive Permission) of Run Command Setting (OW00) to 0
(OFF).
To restart the motor, set parameters using the following procedure.
1.
Change Command (OW08) to NOP (No Command).
2.
Set bit D (Drive Permission) of Run Command Setting (OW00) to 1 (ON).
3.
Change Command (OW08) to the Inverter Drive Control command.
This concludes the procedure to restart the motor.
Inverter Modes
The Inverter has two modes.
Drive Mode: Drive Mode is used for normal operation and to monitor status. You can control
operation from the MP3000 in this mode.
Program Mode: Program Mode is used to set and autotune parameters. In Program Mode, the
Ready status in the Inverter is OFF and commands from the MP3000 are not acknowledged.
To confirm that the Inverter is ready, make sure that bit 6 (Inverter Ready) in M-III Inverter Com-
mand Status (IL2A) is 1 (ON) on the Monitor Parameter Tab Page.
Note: Bit 6 (Inverter Ready) in M-III Inverter Command Status (IL2A) can be monitored only during execution
of the Inverter Drive Control command.
