Each servo drive has current sensors built in. They are required for the control loop electronics. All servo drives I have come across allow you
to monitor the current usually by an analogue voltage output back to your controller. Note most servo drives allow you to measure and monitor other
servo parameters as well, power, temperature, torque, speed and terminal voltage among others. Thus if you have modern AC servos and drives
you don't need to supply any clamp meters or other electronics......just program the drive to output an analogue voltage reflecting the power output.
Easy!
I would guess that your spindle motor, being essentially an AC servo with enhanced field weakening control, will also be able to monitor power and/or
current etc.
Do you actually have the servos and drives? Or more importantly do you have the drive manual.....I'm almost 100% you can monitor power/current
just with a few keystrokes. Likewise do you have a manual for the spindle motor drive?
