PM600 Manual2.1.3 CM12 Checking Stepper ModePM600StepperDriveStepperMotorEncoderThe system consists of stepper motor fitted with an incremental encoder, a stepper drive translator and aPM600 controller.As open-loop, but with an incremental encoder fitted to the motor or mechanism to monitor its actual position.Quadrature signals from the encoder are fed to the PM600 to allow the move to be checked. Any error is notcorrected.2.1.4 CM13 External loop stepper modePM600 Drive BrushlessMotorQuadrature SignalsEncoderorResolverThe system consists of brushless motor fitted with rotation sensor, a drive and a PM600 controller.As open-loop but with the drive correcting for any position errors. The actual position of the motor ismonitored the encoder or resolver fitted to the motor. Quadrature signals generated by the drive or encoderare fed to the PM600 to allow the motor position to be monitored.2.1.5 CM14 Closed loop stepper modePM600StepperDriveStepperMotorEncoderThe system consists of stepper motor fitted with an incremental encoder, a stepper drive translator and aPM600 controller.As open-loop but with an incremental encoder fitted to the motor or mechanism. The actual position ismonitored during a move to detect a motor stall and the end of move criterion. Quadrature signals from theencoder are fed to the PM600 to allow the move to be checked. Any error is automatically corrected.2712 Issue D page 2-2
