[edit] Disclaimer
Zaber’s devices are not intended for use in any critical medical, aviation, or military applications or situations where a product's use or failure could cause personal injury, death, or damage to property. Zaber disclaims any and all liability for injury or other damages resulting from the use of our products.
[edit] Precautions
Zaber’s motion control devices are precision instruments and must be handled with care. In particular, moving parts must be treated with care. Avoid axial loads in excess of the rated thrust load, axial and radial impact, dust and other contaminants and damage to the leadscrew thread. These will reduce the performance of the device below stated specifications.
[edit] Installation
You can mount the NA actuators by the cylindrical mounting shank or by the four mounting holes on the square body section. See the NA web page for dimensions, resolution and other details.
[edit] Operation
The NA actuators are designed to be controlled with the T-MCA series chopper drive controllers. It is important to know the peripheral id of your motor. If you ever need to restore the correct settings for your NA actuator, send restore settings (command 36) with the peripheral ID as the data.

[edit] Alternate Controllers
The actuators may be controlled by any 2-phase stepper motor controller with home sensor input. Warning: Operating the actuator without correctly wiring up the home sensor can cause permanent damage to the actuator. We do not recommend using your own controller unless you are familiar with how to control a stepper motor with a hall sensor limit switch. The following information is provided for reference only. Damage to the actuator or hall sensor due to incorrect wiring is not covered by warranty.
[edit] Home Sensor Wiring
The actuator uses a magnetic hall sensor to detect the home position. The hall sensor has an open-collector output. The default output is high impedance when the hall sensor is not active. When the sensor detects a magnet, the hall sensor pulls the output low to ground.
If you are not using the T-MCA controller, ensure that your controller has a pull-up resistor on the output line of the hall sensor as shown in the diagram. The bypass capacitor is optional, but may help to eliminate false triggering in noisy environments. The typical value for the pull-up resistor (RLOAD) is 10k and for the bypass capacitor is 0.1uF to 1uF. The larger the capacitance, the better the noise filtering but the slower the response time.
