3.6. Access to the VF-AS1/PS1 parameter When access to the VF-AS1/PS1 parameter, set “1” to the PNU. The communication
number of the inverter parameter is set to the subindex IND.
Refer to the inverter instruction manual about the communication number and unit.
3.6.1. Examples of reading or changing the VF-AS1/PS1 parameter
3.6.1.1. Example 1. Reading the basic parameter (cmod (command mode selection))
AK = 6 (Request parameter value (array))
SPM = 0
PNU = 1
IND = 0x0003 (cmod communication number)
PKE
0 1 1 0 0 0 0 0 0 0 0 0 0 0 0 1
6 0 0 1

Response (Value: 0x0001 = Operation panel))
40 01 00 03 00 00 00 01 ･･･ ･･･
3.6.1.2. Example 2. Reading the extended parameter (f219 (RX input point 2 frequency))
AK = 6 (Request parameter value (array))
SPM = 0
PNU = 1
IND = 0x0219 (f219 communication number)
PKE
0 1 1 0 0 0 0 0 0 0 0 0 0 0 0 1

60 01 02 19 00 00 00 00 ･･･ ･･･
Response (Value: 0x1770 (= 6000 -> 60.00Hz*))
40 01 02 19 00 00 17 70 ･･･ ･･･
* “0x1770” as reading value of “RX input point 2 frequency” is
0x1770 = 6000 (decimal number)
Since the unit of “RX input point 2 frequency” is 0.01Hz, set the following value.
6000×0.01 = 60.00Hz
