Stepper Motors

• Can I use the AZ Series Ethernet IP Driver with a 3rd party stepper motor?
• Difference between a servo and a stepper?
• I'm concerned about the heat (surface temperature) of stepping motors (including αSTEP). Is this abnormal?
• What is the allowable inertia ratio for your stepper motors?
• What is the automatic current cutback function of stepping motor drivers?
• How can I minimize Noise?  
• Is there a way to calculate stepper motor output?
• What is the difference between the READY output and PLS-RDY output of the AZ series?
