FEC Micro NR Operations Manual 4.7 Chapter 4: System Setup and Wiring (Rev2.1: 12/12) Tool Connection { Tools are connected to the MNR controller using one cable (Cable supplied standard with each spindle). One cable contains the motor, resolver and torque transducer signal cables. Cable should be securely tightened to the motor to insure complete connection. { If cable ties are required, cable ties should be loose enough to allow the cable to move, but yet hold it in place.
Chapter 4: System Setup and Wiring 4.7.1 Cable Installation Guidelines Improper installation of cables can reduce cable life expectancy drastically. The following guidelines should be used when installing cables. The cables must be prepared for installation without twists, bends or kinks. Upon unpacking the cables, any tie wraps used in shipping should be removed.
FEC Micro NR Operations Manual 4.7.2 Chapter 4: System Setup and Wiring (Rev2.1: 12/12) Considerations for Cable Trolleys Cables hung by festooning type systems must be secured to the individual cable trolley and positioned to avoid sharp bends and eliminate or minimize any torsion twisting. Restraint cords should be used in between cable trolleys to limit movement and reduce the stress on cables as they are extended.

Chapter 6: Fastening Instructions 6.1 Fastening Control. The Micro NR is presentable from two different fastening methods, by parameter setting Torque Control or Angle Control methods. (Based on parameter setting) NOTE: All setting recommendations are based upon common fastening applications. Applications that experience high prevailing torque, excessive joint compression or other unique characteristics must be set with these characteristics in mind. 6.1.1 Torque / Angle Method - Target Torque Control.
FEC Micro Nutrunner Operations Manual Chapter 6: Fastening Instructions (Rev.
Chapter 6: Fastening Instructions 6.1.2 Torque / Angle Method - Target Angle Control. Fastening is performed based upon attaining a desired Angle value, while monitoring the Torque of the fastener and time. Additional monitor items (limits) can be set to enhance the system’s ability to determine if the fastener was properly secured (Section 6.2). { Fastening explanation 1. After start signal command the system runs INITIAL SPEED until INITIAL TIME expires. 2.

Chapter 6: Fastening Instructions 6.2 Speed Functions The Micro NR System is user-programmable for operations involving multiple speed settings. The use of multiple speeds during the fastening process aids in socket engagement, achieving cycle time and controlling the applied torque during all stages. Special conditions that affect these operations will be identified in the appropriate section. 1. Fastening Initial stage to seating process: a.
FEC Micro Nutrunner Operations Manual Chapter 6: Fastening Instructions (Rev. 2: 02/12) The graphic below describes the ideal relationship between torque and speed. Typically for high motor durability, high speed (FREERUN speed) should slow to SLOWDOWN SPEED before the fastener seats. Final TORQUE SPEED should not exceed 50 RPM.
Chapter 6: Fastening Instructions 6.3 Reverse Function The Micro NR System is capable of reverse operations using the manual reverse input on the MNR unit front panel or via the PLC input. The PLC input can be used for automated reverse operations. The motor will reverse as long as the reverse signal or manual button is enabled. Time/Revolutions 54: Reverse Speed RPM FIG.
FEC Micro Nutrunner Operations Manual 6.4 Chapter 6: Fastening Instructions (Rev. 2: 02/12) Special Functions 6.4.1 One Pulse Reverse Function One Pulse Reverse is used in applications where socket to fastener tolerances allow the fastener to “stick” or lock into the socket during fastening operations.
Chapter 6: Fastening Instructions 6.4.2 Rundown Revolution Limits Rundown Revolution high and low limits can be set to identify fasteners that may be too long or too short for normal operations or for a redundant check for bolts that reach torque but are not seated. This is especially the case where different length fasteners are used and placed by hand. The number of rundown revolutions until fastening end is monitored and judged.
FEC Micro Nutrunner Operations Manual 6.4.3 Chapter 6: Fastening Instructions (Rev. 2: 02/12) Torque Inhibit The Torque Inhibit function is used to ignore high torque spikes during initial starting of the motor or fastening process. Under normal fastening operations peak torque will stop the fastening process (if Standard Torque is reached). This may not be desirable for applications with high starting torque and lower fastening torque.
