This output must be connected to the positive lead of the DC motor. The voltage seen at
this pin is pulse-width modulated with maximum amplitude of 47 VDC.
This output must be connected to the negative lead of the DC motor. The voltage seen at
this pin is pulse-width modulated with maximum amplitude of 47 VDC.
This output must be connected to Winding A+ lead of a two-phase stepper motor. The
voltage seen at this pin is pulse-width modulated with maximum amplitude of 47 VDC.
This output must be connected to Winding A- lead of a two-phase stepper motor. The
voltage seen at this pin is pulse-width modulated with maximum amplitude of 47 VDC.
This output must be connected to Winding B+ lead of a two-phase stepper motor. The
voltage seen at this pin is pulse-width modulated with maximum amplitude of 47 VDC.
This output must be connected to Winding B- lead of a two-phase stepper motor. The
voltage seen at this pin is pulse-width modulated with maximum amplitude of 47 VDC.
This input is pulled-up to +5 V with a 2.2 kΩ resistor by the controller and represents
the stage positive direction hardware travel limit.
This input is pulled-up to +5 V with a 2.2 kΩ resistor by the controller and represents
the stage negative direction hardware travel limit.
These A and /A inputs are differential inputs. Signals are compliant with RS422
electrical standard and are received with a MC3486 differential line receiver. A resistor
of 120 Ω adapts the input impedance. The A and /A encoder signals originate from the
stage position feedback circuitry and are used for position tracking.
