RTLC20/FASTRACK carrier installation

During handling or installation of the FASTRACK carrier suitable gloves should be worn to protect against injury from sharp edges.

If required cut the FASTRACK carrier and scale to

length (separately) using guillotine (A-9589-0071) after referring to installation drawing.

The guillotine should be held securely in place, using a suitable vice or clamping method.

Feed FASTRACK carrier or scale through the guillotine as shown, and place the guillotine press block down onto the FASTRACK carrier or scale.

Ensure the block is in the correct orientation (as shown). Whilst holding the block in place, in a smooth motion, pull down the lever to cut through the FASTRACK carrier or scale.

DO NOT CUT

FASTRACK carrier in these areas

Before sticking the FASTRACK

carrier to the substrate bend the centre section upwards slightly using a small pair of pliers.

Guillotine press block

Remove backing liner and stick to substrate, locating

against ledge/separate straight edge(s) or dowels.

Ensure complete adhesion to the substrate by

applying rm nger pressure along the length

of the FASTRACK carrier from the centre outwards towards each end using a lintfree cloth if required.

NOTE: Allow the FASTRACK carrier

a minimum of 20 minutes to adhere before removing the centre section.

Engage centre section removal tool and with consistent forward pressure remove centre section.

If the ledge method or similar is used then the appropriate side panel on the removal tool (A-9589-0122) will need to be removed as shown.

Thoroughly clean and degrease the

substrate and allow to dry.

For the FASTRACK carrier location a ledge, separate straight edge(s) or dowels can be used.

Check alignment of ledge/separate

straight edge(s) with respect to axis

of motion (see ‘RTLC20/FASTRACK

Reference mark selector and limit magnet installation

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 and aligned with the outer edge of the FASTRACK carrier. Limit magnets can be positioned at any user‑dened location along the FASTRACK carrier, but the reference mark selector magnet should be positioned adjacent to the selected IN-TRAC reference mark as shown below.

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/FASTRACK

carrier 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.

X The reference mark selector and limit actuator locations are

correct for the readhead installation shown.

X All limit and reference selector magnets should be aligned

with the outer edges of the FASTRACK carrier.

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

the readhead, may cause false activation of the limit and reference sensors.

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 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.

If required, ensure reference mark selector magnet is correctly positioned (see ‘RTLC20/FASTRACK carrier 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 10). 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 readhead and scale apply cleaning uid sparingly; do not soak.

To set nominal rideheight, place the black 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 10).

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 9. 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 slower) 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/FASTRACK carrier 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 start 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, see page 9.

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.
