Typical inputs, output connections
The limits and home typically are connected to 5V TTL signal, they are active when there is a 5V drop
and
– pins. A current limit resistor is required between the Fault+ and external 5V supply. Typically
a 10K resistor is used for 5V supply. The maximum voltage between Fault+ and Fault- is 50V.
Switch Settings
Disconnect AC power from the unit prior to attempting to change any switch settings. The switch settings
control the maximum winding current, 3rd harmonic correction, and test mode.
The two dip switches are accessible from the bottom of the box. The following graphic shows the location of
2 switches. Switch1 (SW1) is the on the left hand side in the graphic.

The tables below list the dip switch settings for various motor currents, motor waveform and various RS232
communication options.
