Inputs & Outputs
Q Programmer
Q Programmer is used to create and edit stand-alone programs
for Q version drives. The functions of these drives include multi-
tasking, math, register manipulation, encoder following, and
more.
ST Configurator
Used for setup and configuration of the drive+motor. For more
information about the ST Configurator visit the Applied Motion
Products Web site.
Help Manuals
ST Configurator incorporates new on-line help menus. All the
technical data, application information and advice on setting up
the drive is now just a mouse click away.

Encoder Option
The STM drive+motor is offered with an optional 1000 line encoder that
is integrated into the housing of the motor, without increasing the size of
the unit.
The encoder feedback option provides the following functionality:
Stall Detection: The drive detects if the motor has stalled and
triggers a fault.
Stall Prevention: The drive automatically senses rotor lag and
reduces motor speed to avoid stalling. This way the move is
completed, but takes longer.
Position Maintenance: When the motor is stopped, the encoder
detects if the shaft is being moved out of position by an external
force. The motor is then moved back to the correct position.
Align to Index Pulse: The encoder has an index pulse that can be used
for precise repeatable alignment of the motor shaft.
