5.9 Menu 8: Digital I/O
The drive has nine digital I/O terminals (T24 to T29, two relays and an enable input) and two buttons. Each input has the same parameter structure.
The digital inputs are sampled every 4 ms, except when inputs are routed to the limit switch Pr 6.35 and Pr 6.36 when the sample time is reduced to
250 µs. The digital input hardware introduces a further 100 µs delay. The digital outputs are updated every 4 ms. Any changes to the source/
destination parameters only become effective after a drive reset is activated.
