Note:
  • EMC: For a DC power supply line longer than 30 m or when using the motor on a DC bus, additional interference-suppression and protection measures are necessary.
  • ► An EMI filter is to be inserted in the DC supply line as close as possible to the controller/motor.
  • ► Long data or supply lines are to be routed through ferrites.

Note:
  • For the digital inputs, the switch-on threshold is 1.79 V and the switch-off threshold is 1.11 V (depending on the power supply at pins 53/54, typical values @3.3 V). The maximum sampling frequency is 1 MHz. If the I/O pins are used as output (see Defining input and output assignments), the maximum admissible current is approx. 10 mA at 3.3 V DC.
Tip: You can find information on the design of your motherboard in chapter Hardware installation.
