In addition to controlling speed with position feedback, the RMC100 is able to control speed with a tachometer feedback. To do this, an analog module with drive outputs is required. For details on configuring the module for your control and transducer type, refer to Using Analog Channels as Velocity Inputs, and Configuring the Analog Transducer Type.
The procedure for speed control with tachometer feedback is similar to speed control with position feedback. However, a tachometer with analog feedback will often have a small offset. When the tachometer is stopped, the feedback voltage may be slightly different than zero. This may cause the axis to rotate slowly when it has been commanded to stop in closed loop control. To adjust the tachometer feedback, use the Set Count Offset (#) command.
