Special NOTES

5.1

Pull-up resistor

Pull-Up

The inputs of the drivers namely clock, direction, START/ STOP are open collector inputs.

Open Collector (or Open Drain) output is frequently offered by programmable logics because of their higher safety.

They require an adaptation to the AD driver series with a PULL-UP resistor.

This configuration is necessary for the inputs/outputs 1-7 of all PRECIstep drivers.

The value of resistor used to pull up an open-collector is not critical. Smaller values offer faster switching times at the

price of higher current consumption.

Typical values range from a few thousand to a few hundred thousand Ohms.

Please note that the signal is inversed this way.
