15) Rotate the shaft by hand, or using jog mode of the speed
controller and verify proper direction.
16) Optional Protective Basket: Install
protective basket using either the
T-bolts (fan cover) or bolt to 4.5" C-Face
(bolts provided). Break out section 1
and 2 (see illustration ) on protective
basket. Be certain to pivot the basket
over the encoder connector when
installing. Be certain that the protective
basket does not touch or interfere with
the anti-rotation arm/bracket.
To mount the basket on an 8.5" C-Face:
DO NOT FORCE. Thread the ½"-13
bolts into the motor face, through each
clip (provided with options "F" and
"U") but do not tighten fully. Pivot the basket over the encoder
and pivot each clip over each respective basket bolt hole. DO
NOT FORCE. Tighten each bolt to secure the basket and clip.
Adjusting the Encoder to Eliminate Excess Runout/Wobble:
In a typical installation, a housing movement of 0.005" TIR or less (as
measured at the outside diameter of the main encoder body) will not
have an adverse effect. If excessive housing movement is detected in
the installation:
1)
Disconnect power from equipment and encoder cable.
2)
Check the shaft the HS35M is mounted on for excessive
shaft runout using a dial gauge. NEMA MG1 calls for 0.002"
TIR or less.
3)
Verify that the mounting shaft meets minimum and maximum
diameter tolerances.
4)
Maximize the shaft insertion into the encoder (retaining the
minimum of 1/8" between mounting face and encoder)
5)
Loosen the clamping collar and rotate the motor shaft 180°
within the encoder hollow shaft sleeve. Retighten the
clamping collar.
6)
Loosen the clamping collar; move the split in the clamping
collar over a solid portion of the encoder shaft, retighten the
clamping collar.
If excessive housing movement still exists after the above steps, the
shaft or the encoder may be damaged and should be checked by the
manufacturer.
Shaft Sizes:
HS35M: 1/2"*, 5/8"*, 3/4"*, 7/8"*, 1"*, 1 1/8", 12mm*, 15mm*,
16mm*, 20mm*, 25mm, 30mm
NOTE: *HS35M units may utilize shaft insulating resin
insert; these models from 0.500" to 1.00" [12mm to
20mm] may be resized as needed by interchanging or
removing inserts.
* HS35M at 1 1/8", 25mm, and 30mm cannot be resized.
Consult factory for other shaft sizes not shown.
Shaft Engagement:
HS35M: For end of shaft applications, shaft insertion/engagement
should be 1.25" to 2.06" [32mm to 52mm] with a minimum of 1/8"
[3mm] between encoder and mounting surface. Minimum insertion/
engagement is 1.75" [44mm] for models using a sizing insert. The
HS35M may also be used for thru shaft applications by removing the
end of shaft cover.
For shaft lengths greater than the maximum engagement allowed, end
of shaft mounting may still be employed by using a spacer between
the mounting surface and anti-rotation bracket.
CAUTION
When inserting shafts to a depth over 2.06" [52mm], be
sure to remove the cover to prevent cover contact with
the rotating shaft.
WIRING INSTRUCTIONS
CAUTION
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.
The HS35M encoder can be wired for single phase or two-phase
operation, either with or without complements, with or without
markers. See connector options and wiring diagrams.
CAUTION
When wiring for differential applications (A,A,B,B,Z,Z), A
and A should be wired using one twisted, shielded pair;
B and B should be in a second pair, etc. Failure to use
complementary pairs (say, using A and B in a twisted
pair) will reduce noise immunity significantly.
For encoder output that correctly reflects the direction of rotation,
proper phasing of the two output channels is important. Phase A
channel leads phase B channel for clockwise shaft rotation as viewed
from the back (non-mounting side) of the encoder for standard phasing
options ("A", "C", "E", "G", "J", "M", "P", "R", "S", "U", "V", & "W").
Follow instructions under corrective installation as needed to reverse
the direction of output or purchase HS35M with reverse (Dynapar
HS35) phasing (options "B", "D", "F", "H", "K", & "N").
CORRECTIVE ACTION FOR PHASE REVERSAL
If Encoder Direction is Reversed:
(Note: Avtron offers reverse phasing options for former Dynapar HS35
customers – select wiring option "B" or "D").
1)
Remove power.
2)
Exchange wires on cable, either at encoder cable end, or at
speed controller end (but not both):
a.) Single Ended 2 Phase Wiring (see wiring diagram below)
Exchange A and B at the user end of the wires.
b.) Differential 2 Phase Wiring (see wiring diagram below)
Exchange either A with A in the phase A pair OR B with B in
the phase B pair but NOT b oth.
3)
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. Refer to the "Wiring Diagrams" below for
suggested cable types. General electrical requirements are: stranded
copper, 22 thru 16 gauge (Connector Option "P" can use 14 AWG),
each wire pair individually shielded with braid or foil with drain wire,
0.05 uF maximum total mutual or direct capacitance with outer sheath
insulator.
NOTE
When using the industrial connector ("P", "V", or "Z"
options), the minimum wire size is 20 gage, and 20
gage (only) wire ends must be tinned with solder before
connection at the screw terminals.
*Maximum cable length (and line driver selection) is limited by several
factors: line driver protection, maximum RPM, PPR, output voltage
and cable capacitance. Line driver option 8 permits the longest cable
lengths (up to 2000 feet typically at 5-15V). All HS35M line drivers
have full protection against external faults. These factors may dictate
maximum potential cable length.
