Variable name
Rotation direction

Dir

monitoring
- Explanation
This variable can be used to monitor the direction of motor operation by the inverter. The data
monitored with this variable corresponds to the data monitored by the rotation direction monitoring
function (d003). This variable is read-only.
- Sample program: Program to output the output frequency data to a general-purpose analog output
while operating the motor for reverse rotation at 60 Hz and forward rotation at 60 Hz
