Iout - Hitachi NT2021XA Instruction Manual

Variable name

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. 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

1-word data
: Fetch the output current data.
; When output current is 50% or less, change
the acceleration time to 1 second.
: When output current is 80% or less, change
the acceleration time to 2 seconds.
: When output current is 100% or less, change
the acceleration time to 5 seconds.
: When output current is 150% or less, change
the acceleration time to 10 seconds.
: When output current is 180% or less, change
the acceleration time to 20 seconds.
: When output current is 200% or less, change
the acceleration time to 50 seconds.
: When output current exceeds 200%, change
the acceleration time to 100 seconds.
: Turn Y (00) on when acceleration ends.
