1 Nidec-vtron Makes the Most Reliable ncoders in the World 0. PLSNT VLLY RO INPNN, OHIO -0 TLPHON: () --0 X: () --0 -MIL: W: ncoder Instructions V SMRTach II /" SOLI SHT SRIPTION The vtron Model V SMRTach II is a severe duty incremental encoder (also known as tachometer or rotary pulse generator). When coupled to a motor or machine, its output is directly proportional to shaft position (pulse count) or speed (pulse rate). The V operates down to zero speed and can be used for both control and instrumentation applications. Mechanically, the V mounts on a NM adapter flange or it can be foot mounted by using an optional foot mounting bracket kit. The V utilizes magnetoresistive sensors. This proven technology is ideal for rugged environments since it is immune to contaminants that cause optical encoders to fail. These factors, make the V ideal for demanding industries like paper, metals, and chemical processing. n vtron V SMRTach II is equipped with one or two V sensor modules. ach module has a two-phase output (, ) 0 out of phase, with complements (, ), ( Quad Output). marker pulse with complement (, ) is also present. Output resolution on the V is determined by the sensor only. Unlike older models, any PPRs can be mixed and matched. Selection of the rotor is based only on the shaft mounting requirements (and not PPR). NOT Special option 00 selects an alternate PPR code definition. xample: - PPR with option code 000. *-0 PPR with option code 00. The V removable sensor assembly has a diagnostic package that includes daptive lectronics and a ault-heck output. PTIV LTRONIS perfect duty cycle consists of a waveform whose high and low conditions are of the same duration (0%/0%). It is possible over time for duty cycle and edge separation to change due to component drift, temperature changes or mechanical wear. The daptive lectronics extend the life of the V by constantly monitoring and correcting duty cycle and edge separation over time. ULT-HK If the daptive lectronics reach their adjustment limit, the ault- heck alarm and L will notify the drive and operator of an impending failure. This output can occur before a failure, allowing steps to be taken to replace the unit before it causes unscheduled downtime. ault-heck annunciation is available as an alarm output through the connector or as an integral L.

XMPL: or a size Thomas Miniature oupling angular misalignment must be less than., parallel misalignment less than 0.0", and axial float less than ±0.0". The encoder should not be subjected to any axial thrust. Overhung loads should also be minimized. Installations using timing belts/pulleys should have just enough belt tension to eliminate belt sag. xcessive tension will shorten belt and bearing service life. If a rubber slinger disc is used, position it on the shaft so it will rotate freely. UTION o not force or drive the coupling onto the shaft, or damage to the bearings may result. The coupling should slide easily on the shaft.

3 The NM face is the preferred mounting method for the V. In certain cases, however, it may be necessary to footmount this unit. The optional foot mounting bracket kit, Option, will be required for standard installations or replacement of Northstar RIM00 units. To replace or units, use Option foot mount kit. Read all of the following instructions and the vtron PULS GNRTOR HNOOK prior to beginning any work. The V performance and life will be directly affected by the installation. ollowing this sequence of steps is recommended. ) lean and inspect motor/driver shaft. o not use force to assemble coupling onto motor/driver shaft. The foot mounting bracket must be secured to a flat, rigid, vibration free steel or aluminum base which can be machined to accept /- mounting hardware. ) Temporarily mount the V to the foot bracket, install the coupling to the V and driver, and verify that the location is suitable for installation. ) If the V encoder, bracket and coupling are suited to the area, check motor/encoder shaft alignment with a straight edge from multiple positions around the shaft circumference to verify that it meets specifications. ) While maintaining alignment, precisely mark the position of the foot bracket on its mounting base. ) Remove the V.

6 MINTNN GNRL This section describes routine maintenance for the vtron V ncoder. or support, contact vtron s field service department at --0. or emergency after hours service contact us at --. The V SMRTach II circuitry includes a diagnostic package that includes daptive lectronics and a ault-heck output. PTIV LTRONIS perfect duty cycle consists of a waveform whose high and low conditions are of the same duration (0%/0%). It is possible, over time, for duty cycle to change due to component drift, temperature changes, and mechanical wear. The V adaptive electronics extends the life of the V by constantly monitoring and correcting duty cycle over time. ULT-HK fter power-up and the internal rotor position is checked by the sensor, the ault-heck L will turn green. If the adaptive electronics reach their adjustment limit for any reason, the ault-heck alarm and L will notify the drive and operator of an impending failure. The L will turn red if the daptive lectronics reach their adjustment limit. This output occurs before an actual failure, allowing steps to be taken to replace the unit before it causes unscheduled downtime. ault- heck annunciation is available as an alarm output through the connector and as an integral L. TROULSHOOTING: If the drive indicates a loss of encoder/tach fault and the V fault-check L is not illuminated, check the encoder power supply. If power is present, check polarity: one indicator of reversed power supply is that all outputs will be high at the same time. If the drive indicates encoder fault, but the L shows, then check the wiring between the drive and the encoder. If the wiring appears correct and in good shape, test the wiring by replacing the V sensor module. If the new module shows, and the drive still shows encoder loss/tach fault, then the wiring is faulty and should be repaired or replaced. If the alarm output and/or L indicate a fault ():. Remove an end sensor plate or the second sensor, and use the built-in gauge to check the location of the rotor (see igure ).. Remove the V sensor from the housing. lean the hous ing mounting surface for the V sensor and the V hous ing. If the alarm output and/or L indicate a fault () on a prop erly mounted V sensor and the rotor is properly located, replace the V sensor. n oscilloscope can also be used to verify proper output of the V encoder at the encoder connector itself and at the drive/controller cabinet. If the outputs show large variations in the signals at steady speed (jitter or accordion effect, figure ), check rotor position. If the rotor position is correct, the motor or shaft may be highly magnetized. Replace any magnetized shafts with non-magnetic material (stainless/aluminum). onsider replacing the sensors with super-shielded models, option -00. WIRING INSTRUTIONS UTION Remove power before wiring. or bidirectional operation of the -phase SMRTach II, proper phasing of the two output channels is important. Phase channel leads Phase channel for clockwise shaft rotation as viewed from the anti-drive or accessory end of the motor (V mounting end). Wiring option G provides a pinout compatible with Northstar encoders, with a cable shield connection on pin 0. Note that this option does not ground the shield; vtron still recommends grounding the shield at the drive end of the cable for all wiring options. ORRTIV TION OR PHS RVRSL ) Remove Power. ) xchange wires on cable, either at encoder cable end, or at speed controller end (but not both). a) Single nded Phase Wiring (see wiring diagram) xchange and at the use end of the wires. b) ifferential Phase Wiring (see wiring diagram) xchange either with in the phase pair OR with in the phase pair but NOT both. ) pply Power. ) 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 below are based on typical applications. Refer to the system drawing for specific cable requirements where applicable. Physical properties of cable such as abrasion, temperature, tensile strength, solvents, etc., are dictated by the specific application. General electrical requirements are: stranded copper, thru gauge ( PI options can use -0 WG), each wire pair individually shielded with braid or foil with drain wire, 0.0 u maximum total mutual or direct capacitance, outer sheath insulator,,000 ft. max. See Wire Selection hart below for some suggested cables. NOT When using the industrial connector ( G, P, V, or options), the minimum wire size is 0 gauge, and 0 gauge (only) wire ends must be tinned with solder before connection at the screw terminals.
