Start-up of the host system (master)
•
Aer the start-up, the master communicates the structure of the cyclic frames to the inver-
ter (slave) via the conguraon frame (CHK_CFG).
•
The inverter checks the conguraon. If the conguraon is accepted, the inverter
changes from the "Wait Conguraon" state to the "Data Exchange" state. It is now possi-
ble to exchange user data with the master.
•
The internal mapping of the process data is set in 0x24E0:001 ... 0x24E0:016 (direcon
Master → Inverter) and 0x24E1:001 ... 0x24E1:016 (direcon Inverter → Master). Format:
0xiiiissll (iiii= Index hexadecimal, ss= subindex hexadecimal, ll= data length hexadecimal)

Restart or stop communicaon
The 0x2340 parameter can be used to restart or stop communicaon. Oponally it is also pos-
sible to reset all communicaon parameters to the default status.
A restart of communicaon is required aer changes of the interface conguraon (e. g. sta-
on address and baud rate) in order that the changed sengs become eecve.
For restarng communicaon, there are two opons:
a)
Switch inverter o and on again.
b)
Set the selecon = "Restart with current values [1]" in 0x2340.
