Operation

This chapter will present a brief introduction on how to test and operate an AZ servo drive. Read through this 
entire section before attempting to test the drive or make any connections.

Getting Started

To begin operation with your AZ drive, be sure to read and understand the previous chapters 
in this manual as well as the drive datasheet. Be sure that all system specifications and 
requirements have been met, and become familiar with the capabilities and functions of the 
AZ drive. Also, be aware of the 

“Troubleshooting”

 section at the end of this manual for solutions 

to basic operation issues.

Input/Output Pin Functions

The family of AZ drives provide a number of various input and output pins for parameter 
observation and drive configuration options. Consult the drive datasheet to see which 
input/output pin functions are available for each drive.

Current Monitor Output   

The current monitor pin is available on all AZ drive models. Measured 

relative to signal ground, it provides an analog voltage output signal that is proportional to the 
actual current output. The scaling factor for each individual drive can be found on the drive 
datasheet.

Example Measurement

The current monitor pin on an AZ drive with a current monitor scaling factor of 4 A/V is 
measured to be 1.3V. This would mean the drive is outputting: (4 A/V)(1.3V) = 

5.2A

.

Current Reference Output   

The current reference pin is available on all AZ drive models. 

Measured relative to signal ground, it provides an analog voltage output signal that is 
proportional to the command signal to the internal current loop. When the drive output
