Installation procedures should be performed only by qualified
personnel. Safety precautions must be taken to ensure machin-
ery cannot rotate and all sources of power are removed during
installation.
ROTOR INSTALLATION
The motor shaft must project at least 16mm from the motor
face. For set screw rotors only: Apply anti-seize compound to
the motor shaft. For all rotors: Slide the rotor onto the shaft with
the marking “This side out” facing out (away from the motor
face). The rotor centerline must match the sensor centerline. To
accomplish this, use the rotor locating gauge (A28503) and slide
the rotor onto the shaft until it is in the proper position as shown
in Figure 1. If a guage is not available, use the stator housing
alignment grooves as show in Figure 3.
STANDARD CAM SCREW ROTOR INSTALLATION
Turn the cam screws of the rotor in the directions shown on the
rotor to engage the cams. Tighten to 5.6 - 6.8 N-m (See Figure2)
using the 3mm hex wrench. Total cam screw rotation will be less
than one turn.
DESCRIPTION
The Avtron AV115 is a modular, two piece incremental encoder
(also known as a tachometer or rotary pulse generator). It provides
a two phase, A Quad B frequency (pulse) output, with comple-
ments. The AV115 mounts on a 115mm C-Face, also known as
a B-Flange.
Because the AV115 is modular, there are no bearings or
couplings required. This, combined with the latest magneto-
resistive (MR) sensor technology, allows the AV115 to
provide superior mechanical performance and increased reliability.
An Avtron AV115 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.
Output resolution on the AV115 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 require-
ments (and not PPR).
NOTE
Special option 002 selects an alternate PPR code
defini tion. Example: A-128 PPR with option code
000. A*-1270 PPR with option code 002.
INSTALLATIONs
Refer to the back page of these instructions for outline and
mounting dimensions. Axial float or endplay must be less than
±1.27mm.
In preparation for installing the Model AV115 pulse generator, 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.
