Connecting high-speed digital inputs, temperature monitoring for external braking resistor and fail-safe
digital input
Digital inputs DI 0 and DI 1 are high-speed digital inputs and can be used as measuring inputs.
Digital inputs DI 2 and DI 3 form a fail-safe digital input.
The temperature monitoring for an external braking resistor can be connected to DI 4. When
the temperature of the external braking resistor is too high, the converter shuts down the motor.
