Figure 9-9 Menu 8 Relay output logic diagram
The drive has eight digital I/O terminals (T22, T24 to T29 and the relay) and an enable input. Each input has the same parameter structure. The digital
I/O is sampled every 2 ms, except when inputs are routed to the limit switches Pr 06.035 and Pr 06.036 when the sample time is reduced to 250 s.
Any changes to the source/destination parameters only become effect after drive reset is activated.
