Permissible conductor cross-sections for single-conductor connection or for connecting flexible
cables with end sleeves:
● 0.2 mm
● AWG: 26 ... 12
Connecting digital inputs
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 Failsafe Digital Input.
You can connect the temperature monitoring for an external braking resistor to DI 4.
When you use the temperature monitoring function, the converter shuts down the motor if the
external braking resistor temperature becomes too high.
The terminals are spring-loaded terminals
