Iout

Output current
monitoring
- 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.
- Sample program: Program to accelerate the motor while increasing the acceleration time when output
current is high

: Set output current of 200% in variable "U (00)".
: Set output current of 180% in variable "U (01)".
: Set output current of 120% in variable "U (02)".
: Set output current of 100% in variable "U (03)".
: Set output current of 80% in variable "U (04)".
: Set output current of 50% in variable "U (05)".
Default
- 0.01 %
: Fetch the output current data.
then LBL1 : When output current is 50% or less, change
the acceleration time to 1 second.
then LBL2 : When output current is 80% or less, change
the acceleration time to 2 seconds.
then LBL3 : When output current is 100% or less, change
the acceleration time to 5 seconds.
then LBL4 : When output current is 150% or less, change
the acceleration time to 10 seconds.
then LBL5 : When output current is 180% or less, change
the acceleration time to 20 seconds.
then LBL6 : When output current is 200% or less, change
the acceleration time to 50 seconds.
then LBL7 : When output current exceeds 200%, change
the acceleration time to 100 seconds.
then LBL9
: Turn Y (00) on when acceleration ends.
