X Clean shaft taper and internal taper of RESM40 as
recommended in the storage and handling section.
X Insert the rst screws:
- For RESM40 rings with 6, 9 or 18 mounting
holes, use 3 equally spaced M3 screws.
- For RESM40 rings with 12, 16 or 20 mounting
holes, use 4 equally spaced M3 screws.
NOTE: Do not lubricate screws.
NOTE: Recommended screw type M3 × 0.5:
ISO 4762/DIN 912 grade 10.9 minimum/ANSI
B18.3.1M.
X Insert the screws so that the RESM40 is loosely
connected to the shaft, then roughly align the ring
by eye and touch.
X Lightly tighten the screws. Use a Dial Test Indicator
(DTI) to check the radial displacement at the
screw locations.
NOTE: Disregard the radial displacement between
the screw locations.
Use a DTI with low exertion force to avoid
scratching the scale surface. A DTI with a ruby
ball stylus is recommended as a further precaution
against scratches.
X Adjust the screws to reduce the range of radial displacement. When adjusting, identify the screw
location with the lowest radial displacement and tighten that screw, aiming for the average of the highest
and lowest indicator readings.
X Repeat this process until the DTI readings are within ±5 µm at the screw locations.
NOTE: It may be necessary to loosen screws whilst tightening other screws.
NOTE: At this stage, the screws
should only be lightly tightened
(less than 0.5Nm) to allow
further nal adjustment.
X Insert the next screws:
- For RESM40 rings with 6, 9 or 12 mounting holes,
insert all the remaining M3 screws.
- For RESM40 rings with 16 mounting holes, inser t
3equally spaced M3 screws.
- For RESM40 rings with 18 mounting holes, inser t
6equally spaced M3 screws.
- For RESM40 rings with 20 mounting holes, inser t
8equally spaced M3 screws (in four groups of two)
between existing screws.
X As described in Step 2, adjust all the screws inserted thus
far, so that the radial displacement at each screw location
is within ±5 µm.
X Again, at this stage, the screws should only be lightly
tightened (less than 0.5 Nm).
NOTE: You may notice that the torque required to achieve
the radial displacement tolerance will be slightly higher
during step 3 than during step 2. This is normal.

X Rotate the RESM40 ring, measuring the radial
displacement at all of the screw locations.
X Tighten the screw with the lowest radial displacement so
that it matches the average radial displacement, whilst
ensuring the maximum torque specied in the table is
not exceeded.
X Again, rotate the RESM40 ring and re-check the radial
displacement at all of the screw locations, tightening
the screw with the lowest radial displacement so that it
matches the average.
X Repeat this process until the radial displacement at all
of the screw locations is within ±3 µm and that all screw
torques are within the specied range.
X Excessive tightening of screws can have a small effect on
accuracy. Please contact your local representative for
more details.

QUANTiC quick-start guide
This section is a quick-start guide to installing a QUANTiC readhead.
More detailed information on installing the readhead is contained on page 9 and page 10 of this installation guide.
The optional Advanced Diagnostic Tool ADTi-100* (A-6165-0100) and ADT View software† can be used to aid installation and calibration.
INSTALLATION
Ensure scale, readhead optical window and mounting faces are clean and free from obstructions.
Connect the readhead to receiving electronics and power-up. The set-up LED on the readhead will ash.
Install and align the readhead to maximise signal strength over the full axis of rotation as indicated by a Green ashing LED.
CALIBRATION
Cycle the power to the readhead to initiate the calibration routine. The LED will single ash Blue.
Rotate the scale at slow speed (<100 mm/s), without passing the reference mark, until the LED starts double ashing Blue.
The system is now calibrated and ready for use. Calibration values, Automatic Gain Control (AGC) and Automatic Offset Control (AOC) status, are stored in readhead non-volatile memory at power down.
NOTE: If calibration fails (LED remains single ashing blue), restore factory defaults by obscuring the readhead optical window on power-up (see page 10). Repeat the installation and calibration routine.
*
For more details refer to the ‘Advanced Diagnostic Tool ADTi-100 and ADT View software quick start guide’ (M-6195-9321) and ‘Advanced Diagnostic Tool ADTi-100 and ADT View software user guide’ (M-6195-9413).
†
The software can be downloaded for free from www.renishaw.com/adt.
Reference mark
Move the readhead back and forth over the
reference mark until the LED stops ashing.
No reference mark
If a reference mark is not being used, the calibration routine should now be
exited by cycling the power. The LED will stop ashing.
Page 11

QUANTiC RESM40 angle encoder system installation guide
Readhead mounting and alignment
Mounting brackets
The bracket must have a at mounting surface and should provide adjustment to enable conformance to the
installation tolerances, allow adjustment to the rideheight of the readhead, and be sufciently stiff to prevent
deection or vibration of the readhead during operation.
Readhead set-up
Ensure that the scale, readhead optical window and mounting face are clean and free from obstructions.
NOTE: When cleaning readhead and scale apply cleaning uid sparingly, do not soak.
To set nominal rideheight, place the green spacer with the aper ture under the optical centre of the readhead to
allow normal LED function during set-up procedure. Adjust the readhead to achieve a ashing Green LED for a
complete rotation. The faster the ash rate, the closer it is to optimum set-up.
The optional Advanced Diagnostic Tool ADTi-100 (A-6195-0100) and ADT View software can be used to optimise
signal strength in challenging installations. See www.renishaw.com/adt for more information.
NOTE: When re-installing the readhead factory defaults should be restored, see page 10.

System calibration
NOTE: System calibration, restoring factory defaults, and enabling/disabling AGC functions can also
be carried out using the optional ADTi-100 and ADT View software. See www.renishaw.com/adt for
more information.
Ensure signal strength has been optimised over the full axis of rotation; the LED will be ashing Green.
Cycle the power to the readhead or connect the ‘Remote CAL’ output pin to 0 V for <3 seconds. The readhead
will then single ash Blue to indicate it is in calibration mode as detailed in ‘Readhead mounting and alignment’.
The readhead will only enter calibration mode if the LED is ashing Green.
Step 1 – Incremental signal calibration
XRotate the scale at slow speed (<100 mm/s) or less than the readhead maximum speed, whichever is
slowest, ensuring it does not pass a reference mark, until the LED starts double-ashing indicating the
incremental signals are now calibrated and the new settings are stored in the readhead memory.
XThe system is now ready for reference mark phasing. For systems without a reference mark, cycle the power
to the readhead or connect the ‘Remote CAL’ output pin to 0 V for < 3 seconds to exit calibration mode.
XIf the system does not automatically enter the reference mark phasing stage (LED continues single ashing)
the calibration of the incremental signals has failed. After ensuring failure is not due to overspeed (>100 mm/s),
or exceeding the readhead maximum speed, exit the calibration routine, restore factory defaults as detailed
below, and check the readhead installation and system cleanliness before repeating the calibration routine.
Step 2 – Reference mark phasing
XMove the readhead back and forth over the reference mark until the LED stops ashing and remains solid
Blue. The reference mark is now phased.
XThe system automatically exits the calibration routine and is ready for operation.
XAGC is automatically switched on once calibration is complete. To switch off AGC refer to the
‘Enabling/disabling AGC’ section.
XIf the LED continues double-ashing after repeatedly passing the reference mark it is not being detected.
Ensure correct readhead alignment.
Calibration routine manual exit
XTo exit the calibration routine at any stage cycle the power to the readhead or connect the ‘Remote CAL’
output pin to 0 V for <3 seconds. The LED will then stop ashing.
Restoring factory defaults
When re-installing the system, or in the case of continued calibration failure, factory defaults should
be restored.
To restore factory defaults:
XSwitch system off.
XObscure the readhead optical window (using the spacer supplied with the readhead ensuring the
cut-out is NOT under the optical window) or connect the ‘Remote CAL’ output pin to 0 V
XPower the readhead.
XRemove the spacer or, if using, the connection from the ‘Remote CAL’ output pin to 0 V.
XThe LED will start continuously ashing indicating factory defaults have been restored and the
readhead is in installation mode (ashing set-up LED).
XRepeat ‘Readhead set-up’ procedure.
Enabling/disabling AGC
The AGC is automatically enabled once the system has been calibrated (indicated by a Blue LED).
AGC can be manually switched off by connecting the ‘Remote CAL’ output pin to 0 V for >3 seconds
<10 seconds. The LED will then be solid Green.

LED on the readhead is Red and
I can’t get a Green LED
The signal strength is <50%
X
Check the readhead optical window and scale are clean and free from contamination
X
Restore factory defaults (see page 10) and check alignment of the readhead
X
Check the scale is correct type (RESM40)
X
Check the readhead is the correct conguration for the ring diameter
Unable to get a Green LED around the
full axis of rotation
System run-out is not
within specication
X
Use a DTi gauge and check the run-out is within specications
X
Restore factory defaults
X
Realign readhead to obtain a Green ashing LED at the mid-point of the run-out
X
Recalibrate the system (see page 10)
Can’t initiate the calibration routine Signal size is <70%
X
Realign readhead to obtain a Green ashing LED
During calibration the LED on the
readhead remains single ashing
Blue even after moving around the full
axis of rotation
The system has failed to calibrate the
incremental signals due to the signal
strength being <70%
X
Exit CAL mode and restore factory defaults (see page 10)
X
Check system set-up and realign the readhead to obtain a Green ashing LED around the full axis of rotation
before recalibrating
During calibration the LED on the
readhead is double ashing Blue
even after moving it past the
reference mark several times
The readhead is not seeing a
reference mark
X
Ensure you are moving the readhead past the reference mark several times
X
Check the readhead optical window and scale are clean and free from contamination
X
Check the readhead is congured for ‘All reference marks’ to be output

Troubleshooting (continued)
Fault Cause Possible solutions
No reference mark output
X
Ensure you are not over-speeding the readhead during calibration mode (maximum speed <100 mm/sec) or beyond
the readheads maximum speed (whichever is slower)
X
Calibrate the system (see page 10)
– If the system completes calibration mode then it has successfully seen and calibrated the reference mark
If you still don’t see a reference mark then check the system wiring
– If the system does not calibrate the reference mark (LED on the readhead remains double ashing Blue)
see above for possible solutions
Reference mark is not repeatable
X
The readhead bracket must be stable and not allow any mechanical movement of the readhead
X
Clean the scale and readhead optical window and check for damage then recalibrate the system ensuring
both step 1 and step 2 are completed (see page 10)
LED on the readhead is ashing Red
over the reference mark
The reference mark is not phased
X
Clean the scale and readhead optical window and check for scratches then recalibrate the system ensuring
both step 1 and step 2 are completed (see page 10)

Angular speed depends on ring diameter – use the following equation to convert to rev/min.
Angular speed (rev/min) =
V × 1000 × 60
Where V = maximum linear speed (m/s) and D = external diameter of RESM40 ring (mm)
