Inverter Communication
Instructions
Inverter parameter block write [IVBWR]
This instruction writes the values set in (s3) to specified inverter parameters at one time when parameter
numbers are specified.
IVBWR (s1) (s2) (s3)
Example program
The following program writes the maximum frequency (Pr.1): 120 Hz, minimum frequency (Pr.2): 5 Hz,
acceleration time (Pr.7): 1 s, and deceleration time (Pr.8): 1 s to the inverter (station number 0).
