10.2 Operating Inverters Using an MPE720
10.2.2 Operation Precautions
10-4
10.2.2 Operation Precautions
The phrase “While the inverter is running” used in items (1) through (5) refers to bit 5 (During Running) of the moni-
toring parameter IW10 (Status) being ON. Whenever bit 5 of IW10 is ON, the inverter is considered to be
running, even when the motor is stopped.
The phrase “While the inverter is stopped” used in the items (1) through (5) refers to bit 5 of IW10 being OFF.
( 1 ) Operation When the CPU is Stopped
When CPU STOP is executed from the Machine Controller while the inverter is running (
IW

10, bit 5 = ON)
, the
SVB Module will forcibly stop the inverter, and the forward rotation or reverse rotation bit that is turned ON by the
user application will be forcibly turned OFF.
When CPU STOP is reset to CPU RUN, the SVB Module will continue the forced stop operation.
To restart the motor, execute the following commands:
Set bit D (Drive Permission) of Run Command Setting (OW00) to OFF.
Switch the command to NOP (No Command).
Set the bit D (Drive Permission) of the parameter Run Command Setting (OW00) to ON.
Switch the command to Inverter Drive Control.
If you do not perform the above procedure, bit 0 (Operation Ready) in IW00 (Run Status) will remain OFF.
( 2 ) Change in MECHATROLINK Allocation While the Inverter is Running
While the inverter is running (
IW

10, bit 5 = ON)
, the MECHATROLINK definitions of SVB Definition Window
cannot be saved. Save the MECHATROLINK definition while the inverter is stopped (
IW

10, bit 5 = OFF).
( 3 ) Change in Fixed Parameter Setting While the Inverter is Running
The fixed parameters cannot be saved while the inverter is running (
IW

10, bit 5 = ON)
. Save the fixed parameters
while the inverter is stopped (
IW

10, bit 5 = OFF)
.
( 4 ) Switching between Motion Commands While the Command Control Inverter Drive is
Being Executed
If the command Control Inverter Drive is switched to another command while the inverter is running (
IW

10, bit 5 =
ON)
, the motor will continue running. Note that switching the command to NOP (No Command) also will not stop the
motor.
( 5 ) Motor Stopping Methods
Method 1
While the command Control Inverter Drive is being executed, set the bit 0 (Forward RUN) or bit 1 (Reserve RUN) of
the Input Command (OW10) to OFF.
To restart the motor that has been stopped using this method, set the bit 0 or bit 1 of OW10 to ON.
Method 2
Set the Drive Permission bit of the Run Command Setting parameter (OW00, bit D) to OFF.
To restart a motor that has been stopped using this method, execute the following commands:
Switch the command to NOP (No Command)
Set the bit D (Drive Permission) of the parameter Run Command Setting (OW00) to ON.
Switch the command to Inverter Drive Control.
