The values inside the parentheses are for a pulse plus direction output con-
nection.
In this example, a 5-V input motor driver is used with a 24-VDC power supply.
Be careful to ensure that the Position Control Unit output current does not
damage the input circuit at the motor driver and yet is sufficient to turn it ON.
Take into account the power derating for the 1.6-kΩ resistance.
