Writing a Parameter
When transmitting parameter jobs, please note that the slave will not
directly respond to the job in the parameter channel of the master
telegram but that the positive response may be delayed by one or several
communication cycles. For this reason, the master must repeat the
requested job until it has received the corresponding response from the
slave.
The run-up time parameter (USIP no. = 102
dez
/ 66
hex
) of a frequency
converter should be set to the vlaue 10sec in parameter record 3. Only
the PIDV channel is taken into consideration.
As the run-up time has a converter-internal resolution of 0.01s, a
parameter value of 10 / 0.01 = 1000 (3E8
hex
) must be transmitted for a
period of 10s.
Procedure:
•
Select parameter (P102
dez
+ 1000 = P1102 = P 44E
hex
)
•
Select parameter record 3 (IND = 02)
•
Set parameter word (200
dez
/ C8
HEX
)
•
Check response telegram
In hexadecimal notation, the telegram is made up as follows:
3 4 5 6 7 8 9 10
Parameter PID PID IND IND PV PV PV PV
Value 24 4E 02 00 00 00 00 C8

When the converter has completed the job, it responds with
3 4 5 6 7 8 9 10
Parameter
PID PID IND IND PV PV PV PV
Value 14 4E 02 00 00 00 00 C8
