4.2.4.3 Writing the frequency inverter parameter P105 Index 0 (maximum frequency)
The maximum frequency parameter is to be set to the value 60Hz in data record 1 (Index 0).
Data record 47 is used:
Field Data size Byte Date Explanation
Order reference 1 Byte 1 xx h The order reference is used for the precise allocation of the
TU3-PNT response
Order label 1 Byte 2 02 h Write parameter value (see Section 4.2.3)
Axis 1 Byte 3 01 h Access to FI parameter (0=TU3, 1=FI)
Parameter number 2 Bytes 4

Parameter number P105 (+1000) = 451 h
Parameter index 2 Bytes 6
