It provides a two phase, A Quad B frequency (pulse) output, with complements. Because the M5 is modular, there are no bearings or couplings required. This, combined with the latest magnetoresistive (MR) sensor technology, allows the M5 to provide superior mechanical performance and increased reliability. An Avtron M5 can be configured with one or two independent outputs. Each output has six signals: (A, B) 90 out of phase, with complements (A, B ). A marker pulse with complement (Z, Z ) is also provided. INSTALLATION Refer to the back page of these instructions for outline and mounting dimensions. The motor must comply with 1998 NEMA MG 1, section 4, for tolerances on diameters and runout for shafts and accessory faces. Axial float or endplay must be less than ±0.050". In preparation for installing the Model M5 encoder, it is first necessary to clean both the accessory motor shaft and the mounting face. These surfaces must be inspected and any paint, burrs, or other surface imperfections removed. Installation procedures should be performed only by qualified personnel. Safety precautions must be taken to ensure machinery cannot rotate and all sources of power are removed during installation.

Apply anti-seize compound to the motor shaft. Apply thread locker to the rotor set screw holes, preferably from the inside of the bore. Slide the rotor onto the shaft with the P/N marking facing out (away from the motor face). The rotor centerline must match the sensor centerline. To accomplish this, use the Rotor Locating Gauge and slide the rotor onto the shaft until it is in the proper position as shown in Figure 1. Tighten the rotor set screws to 15 in-lb using the 5/4" T-handle hex wrench. Use only a T-handle or torque hex wrench to tighten set screws; using a right angle wrench will not provide enough holding force, and the rotor may slip.

ROTOR LOCATING GAUGE P/N A850 FIGURE 1 CAM SCREW ROTOR INSTALLATION (Modification options 010 & 01) For high slew rate applications where the motor is accelerating and/or decelerating often, Avtron offers an optional Cam Screw rotor. To install the Cam Screw rotor, apply anti-seize compound to the motor shaft, then slide the rotor onto the shaft until it is in the proper position as indicated by the Rotor Locating Gauge (Figure 1). Tighten the locking cam screws in the direction indicated next to the screw (cw/ccw) using 4- ft-lbs of torque using the 1/8" T-handle hex wrench (Figure ). To ensure torque on small shafts that turn easily, two 1/8" hex wrenches may be used at the same time, or the finger-holes may be used.

Do not adjust the cam screws before motor shaft mounting; bottoming out the screws, or backing them out excessively, can lead to insufficient shaft holding force. Thread Locker is preapplied on the cam screws. STATOR HOUSING INSTALLATION The stator housing is attached to the motor using four socket head cap screws /8-1 x 1" long, locating on a 5.875" bolt circle. Longer bolts, (not included), are required for sandwich installation between a motor and a brake. Install the four mounting bolts using thread locker and torque to approximately 0 to 0 foot pounds using the 5/1" T-handle hex wrench. VERIFY ROTOR LOCATION To ensure the rotor is properly located on the shaft: remove the back cover if factory-preinstalled, and verify that the outer face of the rotor is at the same depth as the alignment grooves, using a straight edge tool. (Figure ) Do not use silicone sealants or caulk of any kind on the motor or encoder face; these can cause misalignment or sensor scraping damage. The M5 electronics are fully sealed; water may enter and leave the rotor area as needed. A drain hole option is available if frequent moisture buildup is expected. COVER INSTALLATION Covers must not interfere with the motor shaft or rotor. The longest shaft that can be used without interfering is 0.9" with a standard flat cover (Cover Style option F ) and.5" with an extended pie pan cover (Cover Style option E ). Through shaft covers with seals are available for sandwich style applications (Cover Style option T ). EXTENDED COVER MOUNT (Cover Style option E ) The extended cover mounts to the encoder housing using quantity 4 #- x 0.1" screws, lock washers, and thread locker. THRU SHAFT AND FLAT COVER INSTALLATION (Cover Style options T and F ) The housing has a machined step in the outboard face to accept the cover and a recessed groove for the retaining ring. Insert the cover, smooth side facing out, fully into the machined step until it seats against shoulder. Using a spiral assembly method, install the retaining ring by first inserting the squared off end into the machined groove. Flex the ring and insert it into the groove walking it around the perimeter (A flat blade screwdriver can be used). Final position should have the ring fully seated into groove. Remove the cover by reversing above procedure, starting with the tang end.

V-RING INSTALLATION FOR THRU SHAFT COVERS (Cover Style option T ) For thru shaft covers, verify that the shaft passes completely through the hole in the cover. Apply a small amount of silicone lubricant to the cover plate around the thru shaft hole. The V-ring seal should compress axially when it is pressed against the clean, smooth face of the cover plate. See Figure 4 for proper installation and V-Ring compression. WIRING INSTRUCTIONS Be sure to remove power before wiring the encoder. Be sure to ground the cable shield: It can be connected to case ground at the encoder, or grounded at the receiving device, but should not be grounded on both ends. Refer to the wiring diagrams for specific information on each option. The M5 can be wired for single phase or two phase, either with or without complements, with or without markers. For bidirectional operation, Phase A channel leads phase B channel for clockwise shaft rotation as viewed from the anti-drive or accessory end of the motor (M5 mounting end). NOTE Avtron s convention for A and B wiring, as well as clockwise rotation, are EXACTLY REVERSED from Northstar (Danaher) Slimline. This means the Avtron THIN-LINE M5 can be installed to an existing connection for Slimline RL5, and it will produce rotation in the expected direction without rewiring. CORRECTIVE ACTION FOR PHASE REVERSAL 1) Remove Power. ) Exchange wires on cable, either at encoder cable end, or at speed controller end (but not both). a) Single Ended Phase Wiring (see wiring diagram) Exchange A and B at the use end of the wires. b) Differential Phase Wiring (see wiring diagram) Exchange either A with A in the phase A pair OR B with B in the phase B pair but NOT both. ) Apply Power. 4) Verify encoder feedback is correct, using hand rotation of shaft, or jog mode of the speed controller. Interconnecting cables specified in the wire selection chart are based on typical applications. Physical properties of cable such as abrasion, temperature, tensile strength, solvents, etc., are dictated by the specific application. General electrical requirements are: strand ed copper, through 1 AWG (Industrial EPIC Connector type options can use 14 AWG), each wire pair individually shield ed with braid or foil with drain wire,.05 uf of maximum total mutual or direct capacitance, outer sheath insulator. See specifications for maximum cable length. Strand ed AWG wire should not be used for cable runs great er then 00 feet. If AWG is used with EPIC type connector options the wire ends should be tinned.
