Description

This signal provides input from the positive-side (forward) travel limit switch.

On power-up or after reset this signal defaults to active low interpretation, but

the interpretation can be set to active high interpretation using the

SetSignalSense instruction.

If this pin is not used it may be left unconnected.

This signal provides input from the negative-side (reverse) travel limit switch.

On power-up or after reset this signal defaults to active low interpretation, but

the interpretation can be set to active high interpretation using the

SetSignalSense instruction.

If this pin is not used it may be left unconnected.

This pin can be programmed to track the state of any bit in the status registers.

If this pin is not used it may be left unconnected.

This pin is a general-purpose input that can also be used as a breakpoint input.

If this pin is not used it may be left unconnected.

This pin provides the pulse (step) signal to the motor. A step occurs when the

signal transitions from a high to a low state. This default behavior can be changed

to a low to high state transition using the command SetSignalSense.

If this pin is not used it may be left unconnected.

This pin indicates the direction of motion and works in conjunction with the

pulse signal. A high level on this signal indicates a positive direction move and a

low level indicates a negative direction move.

This signal indicates that the axis is at rest and the step motor can be switched to

low power or standby mode. A high level on this signal indicates the axis is at

rest while a low signal indicates the axis is in motion.

These pins should be connected to the A and B quadrature signals from the

incremental encoder. When the axis is moving in the positive (forward)

direction, signal A leads signal B by 90°.

The theoretical maximum encoder pulse rate is 5.1 MHz. Actual maximum rate

will vary, depending on signal noise.

NOTE: Many encoders require a pull-up resistor on each signal to establish a

proper high signal. Check your encoder’s electrical specification.

If these pins are not used they may be left unconnected.

This pin provides the home signal, a general-purpose input to the position

capture mechanism. A valid home signal is recognized by the motion processor

when ~Home transitions from high to low.

If this pin is not used it may be left unconnected.

If index capture is required, the encoder A and B signals connected to QuadA1

and QuadB1 signals must also be connected to QuadAuxA1 and QuadAuxB1.

The index pin should be connected to the index signal from the incremental

encoder. A valid index pulse is recognized by the motion processor when this

signal transitions from high to low.

If these pins are not used they may be left unconnected.

WARNING! There is no internal gating of the index signal with

the encoder A and B inputs. This must be performed externally if

desired. Refer to the Application Notes section at the end of this

manual for an example.
