Home (Orient) Switch Input The Home or Orient function is active in the Bipolar and Serial modes and causes the motor shaft to rotate to a predefined home position. The homing function allows shaft rotation in the drive forward direction only. The home position is located when a machine mounted switch or the encoder “Index” pulse is activated (closed). Home is defined by a rising signal edge at terminal
A machine mounted switch may be used to define the Home position in place of the encoder index channel. A differential line driver output from a solid state switch is preferred for best noise immunity. Connect this differential output to terminals
A single ended
Note: A control may require dynamic brake hardware for Orient (Homing) function to work. The control may trip without dynamic brake hardware installed.
