probe signals to halt the movement of the machine.
Information to the equipment installer
All Renishaw equipment is designed to comply with the
relevant EC and FCC regulatory requirements. It is the
responsibility of the equipment installer to ensure that
the following guidelines are adhered to, in order for the
product to function in accordance with these regulations:
• any interface MUST be installed in a position away
from any potential sources of electrical noise, i.e.
power transformers, servo drives etc;
• all 0 V/ground connections should be connected to
the machine “star point” (the “star point” is a single
point return for all equipment ground and screen
cables). This is very important and failure to adhere
to this can cause a potential difference between
grounds;
• all screens must be connected as outlined in the
user instructions;
• cables must not be routed alongside high current
sources, i.e. motor power supply cables etc. or be
near high-speed data lines;
• cable lengths should always be kept to a minimum.

Introduction
CNC machine tools using Renishaw NC4 or
NC4+ non-contact (NC) systems for tool setting or
broken tool detection require an interface unit. The
NCi-6 unit converts signals from the NC unit into
voltage-free, solid-state relay (SSR) outputs for
transmission to the CNC machine control.
The NCi-6 interface unit should be installed in the
CNC control cabinet. Where possible, site the unit
away from potential sources of interference such
as transformers and motor controllers.
CAUTION: Only qualified persons should install
and adjust switches on the interface. Remove
the DC power supply from the NCi-6 unit before
removing the cover.
Power supply
The NCi-6 interface can draw its power from the
CNC machine’s nominal 12 Vdc to 24 Vdc supply.
This must be an appropriate single fault tolerant
power supply which must comply to BS EN 609501:2006+A2:2013
(IEC 60950-1:2005+A2:2013).
General
The supply to the NCi-6 is protected by a 0.5 A
resettable fuse. To reset the fuse, remove the
power then identify and rectify the cause of the
fault.
The nominal current when connected to an NC
unit is as follows:
NC4 or NC4+ 120 mA @ 12 Vdc,
70 mA @ 24 Vdc
NOTE: To disconnect the power supply, remove
the wires from the terminals.
Input / output over-current
protection
Each of the SSR outputs is protected by a 50 mA
resettable fuse.
The auxiliary relay output is protected by a
200 mA resettable fuse.
The NC4 and NC4+ are protected by a resettable
current protection circuit.

10-way connector (CN1)
Connector CN1 is used to connect the
non-contact unit to the NCi-6 interface. The
interface automatically detects which NC unit has
been connected.
Terminals 1 – 2
Used to monitor the signal from the NC4 or NC4+.
Voltage range: 0 Vdc to 9 Vdc.
15-way connector (CN2)
Connector CN2 is used to connect the NCi-6
interface to the CNC machine tool.
Terminal 1
Used to select the pulse width in consideration
with switch SW2-4.
Terminals 3 – 6
This is an auxiliary output that can be used to
control external devices. Devices may include an
LED, a buzzer or an air blast.
This output can also be used with a hardwired
NC4 or NC4+ system to switch the transmitter unit
on/off independently of the receiver.
Alternatively, it can act as a skip-sharing module to
switch between a non-contact tool setting device
and an interface for spindle probing. This output is
fused at 200 mA.
Terminals 7 – 8
This is an SSR output that can be configured to
be either normally open (N.O.) or normally closed
(N.C.). The output is fused at 50 mA.
Terminals 9 – 10
This is an SSR output that can be configured to
be either normally open (N.O.) or normally closed
(N.C.), as well as providing a pulsed, level or
oscillating output. The output is fused at 50 mA.
Terminals 11 – 12
This is used to select the operating mode.
Terminals 13 – 15
This is used to supply power to the interface.

9Interface LEDs
Interface LED states
Seven LEDs are fitted on the front of the NCi-6
interface. These provide the operator with a visual
indication of the system’s status.
Status LED
The Status LED indicates the status of the
NC system to the operator. The colours and
associated states are described in the table on
pages 11 and 12.
When the system is in set-up mode, the LED
changes from red to amber to green as the beam
voltage increases.
If the LED is green after exiting set-up mode, this
indicates that set-up has been successful. If the
LED is not green, this indicates that set-up has not
been successful and must be repeated.

IMPORTANT: Setting a switch
When setting a switch to either the On or Off position,
apply firm pressure to make sure it is fully in position.
1 Not used On Off Not used.
2 NC set-up On Off Used when setting up an NC4 or NC4+ system. Set
this switch to On so that the alignment voltage can be
maximised. After maximising the voltage, set the switch
to Off so that the automatic gain circuitry can fine-tune
the operating voltage.
3 Drip rejection On Off
When the drip rejection mode is set to On, the effects
of individual drops of coolant on measurements are
filtered out.
NOTE: For safe operation, set the spindle speed and
spindle override as described below.
4 Spindle r/min 500 1000 Used with drip rejection. For safe operation, the spindle
speed must be fixed at a whole multiple, e.g. 1000,
2000, or 3000; or 500, 1000, or 1500, and the spindle
override must be disabled.

CAUTIONS:
With the SSR output switch(es) set to Off, i.e. normally open (N.O.), the respective output will remain in
a non-triggered state if the power supply is interrupted and/or a poor connection is made to the SSR.
If using SSR2 as an oscillating or pulsed output for a trigger signal to the control, the level output SSR1
must be used to guarantee a reliable probe status check
.

SSR2 type 1 and SSR2 type 2
CAUTION: If using SSR2 as an oscillating or
pulsed output for a trigger signal to the control, the
level output SSR1 must be used to guarantee a
reliable probe status check.
The SSR2 output can be configured for three
different types, pulsed, level or oscillating.
The selection of SSR2 type is derived from the
position of two switches, SW2-3 and SW3-4.
The table for this logic is as follows:

NOTE: On certain machine controllers there is a
delay between the start of a measurement move
and the machine controller becoming responsive
to a change in trigger status. In this case use the
oscillating output to ensure the trigger is detected
when the machine controller becomes responsive.

Tool set mode 1
This mode of operation allows functions such as
system alignment, tool calibration, length and
diameter tool setting, and thermal compensation
tracking. Measurement takes place as the tool
enters the laser beam. No M-codes are required.
Typically drip rejection is activated.
Tool set mode 2
This mode of operation allows length and
diameter measurement of cutting tools, measures
run-out and allows cutting edge checking. It uses
“Dual Measurement” technology. Measurement
takes place as the tool exits the laser beam
providing shorter cycle times and is more robust
in wet conditions. M-codes are required to activate
this mode. Drip rejection is not used.
Operating modes
High-speed tool breakage
detection
This mode of operation allows rapid detection
of broken tools that are solid at the centre – for
example, drills and taps.
Latch mode
This mode of operation allows functions such
as checking tools for missing inserts and profile
checking.

(see the table below). These selection levels can
be inverted using switches SW3-1 and SW3-2
respectively so that 0 Vdc is used to activate the
mode and 11 Vdc to 30 Vdc is used to deactivate.
If the M-code voltage is floating when deactivated,
a resistor is required to pull up the voltage to the
supply voltage (refer to the figure opposite).

Pulse width setting
The pulse width setting has the following
functions:
• Sets the SSR2 pulsed output width to either
20 ms or 100 ms. It also sets the minimum
pulse width of SSR1 to either 20 ms or
100 ms.
• If the pulse width is set to 20 ms, the cycle
time for the latch mode functions is reduced
and the spindle speed is five times faster. In
certain cycles ensure the maximum r/min of
the tools is not exceeded.
Operating modes
• Sets the minimum r/min of the tools in tool
set mode 1, without drip rejection active, and
in tool set mode 2.
• Switch SW2-4 sets the pulse width to 20 ms
or 100 ms. M-code 3 can be used to invert
the switch setting as shown in the table
below.
