CAUTION

* When the user program of the computer is used to make the running frequency

setting by RS-485 communication, setting can be made in the minimum setting

 

increments of 0.01Hz, but the setting may be written to the inverter in increments

 

of 0.1Hz. (0 is written in the second decimal place.)

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

POINT

 

 

 

 

 

 

 

 

 

 

 

 

 

 

To make RS-485 communication between the inverter and personal computer, the

 

 

operation mode must be set to the "computer link operation mode".

 

 

Pr. 79 "operation mode selection" ‚ "1, 3, 4"

 

 

and communication parameter n10 "link start mode selection" = "1"

 

 

Reset the inverter after setting the communication parameters n1, n2, n3, n4, n7,

 

 

n11. The values set are registered once the inverter is reset.
