Menu 8: Digital I/O

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
inputs are sampled every 4ms, except when inputs are routed to the limit switches Pr 6.35 and Pr 6.36 when the sample time is reduced to 250μs.
The digital input hardware (excluding the SAFE TORQUE OFF (SECURE DISABLE) input) introduces a further 100μs delay. The SAFE TORQUE
OFF (SECURE DISABLE) input hardware gives a typical delay of 8ms (maximum 20ms). The digital outputs are updated every 4ms. Any changes to
the source/destination parameters only become effective after drive reset is activated.
