Program example for parameter writing

The following program changes the setting of Pr.7 Acceleration time of station 1 inverter to 3.0 s.
• Acceleration time writing instruction code: H87 (hexadecimal)
• Acceleration time set data: K30 (decimal)
For the parameter instruction codes, refer to the Instruction Manual (Detailed) of the inverter.
The reply code at the time of instruction code execution is set to D2. (Refer to
