In position mode, the drive can accept position commands via two digital inputs, using one of these signal
formats: pulse and direction, count up/count down, and quadrature.
In all three formats, the drive can be configured to invert the command.

MOOTHING
In position mode, the drive’s trajectory generator ensures smooth motion even when the command source
cannot control acceleration and deceleration rates.
When using digital or analog command inputs, the trajectory generator can be disabled by setting the Max
Accel limit to zero. (Note that when using the CAN bus, serial bus, EtherCAT, or CVM Control Program, setting
Max Accel to zero prevents motion.)

In pulse and direction format, one input takes a series of pulses as motion step commands, and another input
takes a high or low signal as a direction command, as shown below.
The drive can be set to increment position on the rising or falling edge of the signal. Stepping resolution can
be programmed for electronic gearing.
