- Explanation
This variable can be used to monitor the inverter output current. The data monitored with this variable corresponds to the data
monitored by the output current monitoring function (d002). The monitored data indicates the ratio of present output current to
rated current of the inverter. This variable is read-only. For details, refer to the Inverter Instruction Manual.
- Sample program :
Program to accelerate the motor while increasing the acceleration time when output current is high
