Sink logic, Pr. 185 = 7, Pr. 186 = 6, Pr. 192 = 17, Pr. 193 = 18, Pr. 194 = 19

*3. The terminals used depend on the Pr. 180 to Pr. 186 settings.

Note:

This switch-over function is used in the external operation

mode. Always connect terminals R1, S1 (L

, L

) to a

different power supply (power supply different from the one

for MC1) to ensure proper operation.

MC2 and MC3 must be mechanically interlocked.

*1. Note the sequence output terminal capacities. The terminals used

depend on the Pr. 190 to Pr. 194 settings.
