larger than a NEMA 23, but has the same mounting
dimensions as the NEMA 23. Only the shaft diameter
of the NEMA 24 is larger: 8 mm vs. 0.25 inch
NEMA 24 has more torque than a NEMA 23 Sold & Serviced By:

Shuttle Conveyor
• Solution
Integrated = STM
Analog positioning = Q
No stalling = built‐in encoder for stall prevention

Sold & Serviced By:

ELECTROMATE
www.electromate.com

Component Testing
• One half of electrical connector module is fixed.
• Other half of connector module is mounted to
ballscrew actuator.
• Motor needs to make and break the electrical
connection by cycling the actuator back and
forth.

Sold & Serviced By:

ELECTROMATE

Component Testing
Limited wiring
Test needs to run from PC
Counter display to show cycle count

Sold & Serviced By:

ELECTROMATE
www.electromate.com

Component Testing
• Solution
Limited wiring = STM
Run from PC = S version in SCL mode receives a set
of Feed to Length (relative move) commands for
each cycle
Counter display = digital output from STM drive
increments the counter each cycle
Part number = STM23S‐2AN
Sold & Serviced By:

ELECTROMATE
www.electromate.com

Remote Pan & Tilt
• X‐Y control of HD video camera via remote 2‐axis
joystick
Limited wiring – motors mounted directly to camera
pan & tilt axes
Smooth motion
Good “feel” for operator
Analog joystick control Sold & Serviced By:

ELECTROMATE
www.electromate.com

Remote Pan & Tilt
• Solution
Limited wiring = STM
Smooth motion = anti‐resonance built into current
control of every STM unit
Analog joystick control = S version in velocity mode
can be offset to work with a center‐off, spring
loaded joystick. One STM drive for each axis.
Good “feel” = jerkiness of quick changes in joystick
can be smoothed out with separate drive settings
for accel, decel, and analog filtering Sold & Serviced By:
