MSJR5 Digital Speed Motion Controller with Analog Trim Input

MSJR5 Digital Speed Motion Controller with Analog Trim Input
Description N/A The most economical way to add digitally precise, PID speed regulation to standalone or multi-section systems

The Dynapar™ brand MSJR4 improves the speed regulation and adds new capabilities to variable speed drives. Regulating extruders, mixing pumps or material handling conveyors eliminates speed variations from temperature, power line voltage or motor load changes, and results in consistently higher quality production. The MSJR4 also operates in minutes and seconds, for food and beverage applications that need to control the cooking time of ovens and broilers. 		N/A A new standard for price and performance in full PID digital speed regulation, with analog input for control of dancer position or web tension

The Dynapar™ brand MSJR5 offers improved speed regulation and new capabilities for variable speed drives. It is similar in function to the MSJR4, with the addition of an analog input. In speed control of pumps or conveyors, an easy-to-use operator device for setting the speed is a simple potentiometer. The MSJR5 will adjust and display the setpoint directly from the pot.

Features N/A
  • Leader or follower operation
  • Speed or Process Time (inverse speed) setpoints
  • PID with velocity feedforward
  • Programmable Accel/Decel ramp rate
  • Speed display calibration in engineering units
  • High and Low alarms in setpoint units or percentage of setpoint
  • Three level security of setpoints, loop gains and program data
  • NEMA4/IP66 front panel washdown rating
  • Nonvolatile memory
Installation is simplified through the use of pluggable terminals and simple input and output diagnostics. The rugged metal enclosure and isolated drive output provide complete immunity from electrical noise and the universal power input is fully filtered for low emissions. 		N/A

Additional Information N/A In the follower mode, the MSJR4 will precisely match the speed of one motor, machine section or manufacturing process to another. With the assurance of zero cumulative error (drift) over time, it economically automates transfer lines, coating or draw of plastics film, and paper or plastics winding/unwinding.

Inherent in the MSJR4 is a large, LED display of actual process time or speed, which can be scaled into meaningful units (feet per minute, gallons per second, or RPM) for operator ease in monitoring and setting the desired speed. 		N/A For plastics converting or metal processing applications, the follower capability matches the speed of one section to another. The analog trim input allows direct control of dancer position in web processes, or tension sensing in winding or slitting operations.

The MSJR5 has a large, LED display, which can be scaled to show RPM, feet per minute, or sheets per hour, for easy monitoring and speed setting.
