The converter accelerates the motor at the ramp. When the converter has
reached 50% setpoint value, it will respond by transmitting the following
telegram:

Note: In bit 10 of the response telegram, the status of MFR 1 is
signaled. Depending on the programmed function and state,
the status word may change.
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 (USS no. = 102
dez
/ 66
hex
) of a frequency
converter with the USIP address 3 should be set to the value 10sec in
parameter record 3. There aren't any process data transmitted.
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 10sec. PPO1 is selected as PPO type.
Procedure:
•
Set address (address 03)
•
Select parameter (P 102
dez
/ P 66
hex
)
•
Select job identification (2 = change parameter value (word))
•
Select parameter record 2 (IND = 01)
•
Set parameter value (1000
dez
/ 3E8
HEX
)
•
