Superior * Systems * Solutions Motor Speed Controller Use with AC or DC variable speed drives Security lockout Diagnostics for easy troubleshooting Isolated speed reference signal Optional analog feedback and set point Two optional relay outputs Optional DC input power 10-30 Vdc Product Information Electro-Sensors Model MS320 Closed Loop Motor Speed Controller provides precise regulation of motor speed by controlling the speed reference signal to the variable speed drive. The MS320 monitors a feedback pulse sensor mounted on the motor, or on a down stream shaft, and compensates for any variations between the actual operating speed set point and the desired speed by automatically fine tuning the speed reference signal. The MS320 display can be scaled into meaningful units for operator ease in monitoring and setting In the Master Mode, the MS320 ramps the motor to the selected set point at the programmed acceleration rate. Every 20 milliseconds the MS320 compares the set point with the digital or analog feedback signal. The control algorithm adjusts the speed reference signal to reduce the error to zero. In the Follower Mode, the MS320 controls the motor speed based on a digital or analog lead signal. The follower motor runs at a user selectable ratio based on the lead input signal. The digital or analog feedback signal from the follower is used as a reference to confirm that it is running at the correct ratio, and that any speed error is driven to zero. Diagnostic test procedures are provided for easy troubleshooting of all input and output functions as well as keypad and display operation. A programmable security code and keypad lockout allow the user to protect selectable program variables and front panel functions from unwanted changes during operation. There are three AC inputs, one dedicated for Run/Stop and two programmable for the following: Fast Stop, Jog, Set Point 1, Set Point 2, Scroll Set Point Up, Scroll Set Point Down, Master/Follower, Closed/Open Loop, Speed Command and Signal Reset. Optional Expansion Board The optional expansion board provides the user with two additional inputs programmable for the same functions as the two standard inputs. Two SPST relay outputs are provided and programmable for the following: High Alarm, Low Alarm, Deviation Alarm, Zero Speed, Drive Enable and Ramp Complete. Two analog inputs (4-20 mA or 0-10 Vdc) are provided and programmable for the following: Feedback Frequency, Lead Frequency, Master Setpoint, Follower Ratio, Setpoint/Ratio Trim, Setpoint/Ratio Inverse Trim and Wind/Unwind with Core Calculation. The MS320 is ideal for Packaging Machinery, Centercore and Surface Winders, Wire and Cable Machinery, Feed-to-Stop Systems, Cut Off Machines, Traverse Winding, Ovens and Fans, Pumps, Blenders and Feeders, Overhead/Floor Conveyors and Extruders.
