Analog reference is one of [[Reference signal|reference signal] types used in motion control.

The most typical reference voltage range is +/-10V where

  • -10V equals the most negative reference (-100%)
  • 0V equals zero reference
  • 10V equals most positive reference (+100%)
  • Any value between is interpolated linearly

Another common voltage range is 0..5V where may be zero reference may be at 2.5 VDC.

Example

Lets assume +/-10V is used as torque reference in VSD drive. In this case 0V equals no torque, and 10V equals 100% of peak torque configured in the drive, 5V equals 50% torque etc.

Peak torque can be configured to drive with GDtool as peak current limit. Torque and current are directly proportional, so torque reference is also a current reference.
