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
  • Analog input for remote setpoint or trim adjustment
  • 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.

Additional Information

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.
