1. CLD Series Section 5 Operation Feedback Device Selection Acceptable feedback frequency at any set speed in an application must lie within the 0 3000 Hz range Feedback frequency is directly proportional to the number of feedback pulses per revolution PPR and to the speed of the shaft RPM that the feedback transducer monitors The feedback range relates to the motor speed as follows 600 120 000 PPRminimum PPRmaximum RPMminimum RPMmaximum EXAMPLE 1 Consider an application in which the feedback source is monitoring a driven shaft and not the motor armature shaft This shaft is running at speeds as low as 1 RPM The selected feedback device must produce at least 600 PPR EXAMPLE 2 Consider an application the requires monitoring and controlling a driven shaft at speeds as high as 4000 RPM 120 000 120 000 PPRmaxi maximum APM ee 4000 The selected feedback device must produce 30 or fewer PPR The CLD100 can control armature shaft speeds within a 30 1 speed range Under no circumstances can the CLD100 be expected to control motor speed beyond this speed range CLD Series Select Switches Access the switches from the rear of the CLD100 case Using a screwdriver loosen the two screws that attach the nameplate to the case The switches are visible when the nameplate is removed Line Voltage Switch SW501 The slide switch on the left rear of the CLD100 Figure 7 is the voltage switch Set2.
