Scale application

The scale applicator (A-9589-0115) is designed for use with RTLC20-S scale.

Allow the scale to acclimatise to the installation environment prior to

installation.

Mark out the ‘START’ and ‘FINISH’ points for the scale on the axis

substrate – ensure that there is room for the optional end covers if required

(see ‘RTLC20-S scale installation drawing’ on page 4).

Thoroughly clean and degrease the substrate using recommended solvents

(see ‘Storage and handling’ on page 2). Allow the substrate to dry

before applying scale.

Mount the scale applicator to the readhead mounting bracket using M2.5

screws. Place the shim supplied with the readhead between the applicator and substrate to set the nominal height.

NOTE: The scale applicator can be mounted either way round to enable

easiest orientation for scale installation.

Side mounting scale applicator (A-9589-0115).

Slowly and smoothly move the applicator through the entire axis

of travel, ensuring the backing paper is pulled manually from the scale and does not catch under the applicator.

Clean the scale using Renishaw scale

cleaning wipes (A-9523-4040) or a clean, dry, lint-free cloth.

End covers

The end cover kit (A-9585-0035) is designed to be used with RTLC20-S scale to provide protection for

exposed ends.

NOTE: End covers are optional and can be tted before or after readhead installation.

Move the axis to the scale ‘START’ position, leaving enough room for the

scale to be inserted through the applicator, as shown below.

Begin to remove the backing paper from the scale and insert the scale

into the applicator up to the ‘START’ point (as shown). Ensure the backing paper is routed under the splitter screw.

Apply nger pressure to the scale at the ‘START’ point, using a clean

lint-free cloth, to ensure scale end adheres well to the substrate.

Reference mark selector and limit magnet installation

IMPORTANT: Allow 24 hours after scale application before tting magnets.

For accuracy and ease of positioning of reference mark selector and limit magnets, the applicator tool (A-9653-0201) should be used. The magnet should be attached to the applicator tool as shown below. Limit magnets can be positioned at any

user‑dened location along the scale, but the reference mark selector magnet

should be positioned adjacent to the selected IN-TRAC reference mark as shown.

As the VIONiC readhead passes the reference mark selector magnet or limit

switch magnet, a force of up to 0.2N is generated between the magnet and the concentrators on the readhead. The design of the bracket should be sufciently stiff

so that it is able to tolerate such force without distorting. Following the clamping instructions on the scale installation will prevent this magnetic force from disturbing the scale.

Limit trigger point

The limit output is nominally asserted when the readhead limit switch sensor passes the limit magnet leading edge, but can trigger up to 3 mm before that edge

(see ‘RTLC20-S scale installation drawing’ on page 4).

NOTES

X Reference and limit magnets may creep when inuenced by magnetic materials

in close proximity. In such cases, they should be held in place using an additional llet of epoxy glue or similar along the outer edge of the magnet

assembly. Optional bolted reference and limit magnets are available.

X The reference mark selector and limit actuator locations are correct for the

readhead orientation shown.

X External magnetic elds greater than 6mT, in the vicinity of the readhead,

may cause false activation of the limit and reference sensors.

Datum clamp

IMPORTANT: Allow 24 hours after scale application before tting datum clamp.

The datum clamp (A‑9585‑0028) xes the RTLC20‑S

scale rigidly to the substrate at the location chosen.

CAUTION: The metrology of the system may be compromised if the datum clamp is not used.

The datum clamp does not need to be tted adjacent to a

reference mark. It can be positioned anywhere along the

axis depending upon the customers’ requirements.

VIONiC RTLC20-S installation guide

Remove the backing paper from the datum clamp.

Place the datum clamp with the cut-out against the scale at the chosen location.

A-9585-0028

Place a small amount of adhesive (Loctite® 435™)

in the cut-out on the datum clamp, ensuring none of the adhesive wicks onto the scale surface. Dispensing tips P-TL50-0209 are available.

Ensure the adhesive wicks along the entire length of the cut-out.

VIONiC encoder system quick-start guide

This section is a quick-start guide to installing a VIONiC encoder system.

More detailed information on installing the system is contained on page 8 and page 9 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.

If required, ensure reference mark selector magnet is correctly positioned (see ‘RTLC20-S scale installation drawing’ on page 4).

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 travel 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.

Move the readhead along the scale at slow speed (<100 mm/s), without passing a reference mark, until the LED starts double ashing Blue.

If a reference mark is not being used, the calibration routine should now

be exited by cycling the power. The LED will stop ashing.

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, restore factory defaults by obscuring the readhead optical window on power-up (see page 9). Repeat the installation and calibration routine.

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 sufciently stiff to prevent deection 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 the readhead and scale apply cleaning uid sparingly; do not soak.

To set nominal rideheight, place the green spacer with the aperture 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 along the full axis of travel. 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 9).

System calibration

NOTE: The functions described below 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 along the full axis of travel; 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’

on page 8. The readhead will only enter calibration mode if the LED is ashing Green.

Step 1 – Incremental signal calibration

X Move the readhead along the axis 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.

X The 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.

X If 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

X Move the readhead back and forth over the selected reference mark until the LED stops ashing and

remains solid Blue (or Green if AGC is disabled). The reference mark is now phased.

X The system automatically exits the calibration routine and is ready for operation.

X AGC is automatically switched on once calibration is complete. To switch off AGC refer to the

‘Enabling/disabling AGC’ section.

X If the LED continues double‑ashing after repeatedly passing the chosen reference mark it is not

being detected.

- Ensure that the correct readhead conguration is being used. Readheads can either output all

reference marks or only output a reference mark where a reference selector magnet is tted

depending on the options chosen when ordering.

- Check reference mark selector magnet is tted in the correct location relative to readhead orientation (see ‘RTLC20-S scale installation drawing’ on page 4).

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:

X Switch system off.

X Obscure 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.

X Power the readhead.

X Remove the spacer or, if using, the connection from the ‘Remote CAL’ output pin to 0 V.

X The LED will star t continuously ashing indicating factory defaults have been restored and the readhead

is in installation mode (ashing set‑up LED).

X Repeat ‘Readhead set-up’ procedure on page 8.

Enabling/disabling AGC

The AGC is switched on 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.

Calibration routine manual exit

X To 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.
