For normal communication, the following parameters must be set on the inverter side as noted.
CR/LF instruction presence/absence (Pr. 124): Mode 2 (with CR/LF)
Comm. response waiting time (Pr. 123): 9999 (use the waiting time data)
...
Inverter Setting Example
Parameter Number | Set Value | Description |
1171 | 0 | Station number 0 (any number between 0 to 31) |
1181 | 192 | 19200 bps |
1191 | 0 | 8 data bits, 1 stop bit |
1201 | 0 | No parity |
121 | 9999 | Do not use the communication retry |
122 | 9999 | Do not use the communication timeout |
1232 | 9999 | Response delay is dependent on the received frame. |
1242 | 2 | Use CR/LF terminator |
(Note 1) Those parameters (117 to 120) must be matched with the settings of the Xpanel.
(Note 2) The parameters of 123 and 124 must be set as the value shown in this example. If those parameters are set as other values, Xpanel cannot communicate with the inverter.
Address Notation
The address of the tag in Xpanel has the following format:
