Mitsubishi Electric FR-A700 EC, Инструкция по эксплуатации

Страница: 684 / 826

Special operation Parameter
6 - 504
Connecting the magnetic contactors to the inverter
Parameter setting for source logic:
Pr. 185 = 7, Pr. 192 = 17, Pr. 193 = 18, Pr. 194 = 19
Take caution for the capacity of the sequence output terminal. The used terminal changes
depending on the setting of Pr.190 to Pr. 196 "Output terminal function selection".
When connecting a DC power supply, insert a protective diode. When connecting an AC
power supply, connect arelay output option (FR-A7AR) and use a contact output.
The used terminal changes depending on the setting of Pr.180 to Pr. 189 "Input terminal
function selection".

NOTES Use the commercial power supply switchover function in external operation mode. Be sure
to connect the other power supply since the function is not performed normally unless the
connection terminals R1/L11, S1/L21 are not connected to the other power supply (power
supply that does not pass MC1).
Be sure to provide mechanical interlocks for MC2 and MC3. The inverter will be damaged if
main supply voltage is connected to the output.
