3-39

Motor Speed in RPM Register 217/1217

The Motor Speed in RPM register contains the speed of the motor in

revolutions per minute. A positive number in this register indicates a

forward direction; a negative number indicates a reverse direction.

Units: RPM

Range: N/A

Access: Read only

Note that this register is not intended for closed loop control.

Position Error Register 218/1218

The Position Error register contains the error output value of the

position loop. An error value of 4095 equals one mechanical

revolution of the resolver.

Units: Counts

Range: +/-4095

Access: Read only

Speed Loop P+I Output Register. 219/1219

The Speed Loop P+I Output register contains the proportional and

integral torque output of the speed loop. A value of 4095 equals the

torque limit.
