Pulse/Direction Radio Button
Selecting this radio button puts your drive in Pulse/Direction interpretation. In Pulse Direction mode, pulses are received
on the A channel, and the direction is received on the B channel. If the B is high, pulses received on the A are interpreted
as positive changes to the Pulse Position Input. If the B is low, pulses received on the A are interpreted as negative
changes to the Pulse Position Input.
Pulse/Quadrature Radio Button
Selecting this radio button puts your drive in Pulse/Quadrature interpretation. If Pulse Quadrature is selected, a full
quadrature encoder signal is used as the command. When B leads A encoder counts received are interpreted positive
changes to the Pulse Position Input. When A leads B encoder counts received are interpreted as negative changes to
the Pulse Position Input. All edges of A and B are counted, therefore one revolution of a 2048 line encoder will produce
a 8192 count change on the Pulse Position Input.
Signal Type Group
Differential Radio Button
Selects the differential hardware input of the drive to receive pulses (default) these pulse inputs are as follows:
Differential Inputs are typically needed for pulse rate 250 kHz or high ambient noise environments.
Single Ended Radio Button
Selects the single ended hardware input of the drive to receive pulses (default) these pulse inputs are as follows:
Actual motor rotation direction will depend on pulse ratio polarity and setting of the Polarity Direction bit.
Pulse Mode Ratio Setup Group
Ratio Formula
Defines the number of command pulses it will take to move the motor the distance specified in the Pulse Mode Ratio
Revolutions. The default value is 1 motor revolution per 8192 counts.
The coarsest ratio possible is 10 input counts per motor revolution. Setting a ratio to fewer than 10 input counts per motor
revolution will cause an Overspeed fault without generating motion.
