amplifier.

Conditions for installing the switching unit

- Ambient temperature:

0 to 55°C for the unit

0 to 45°C for the cabinet

- Ambient humidity: 90%RH or less, no condensation

D At the differential speed Rigid Tap, a rotating speed of spindle 2

(commanded speed at Rigid Tap + rotating speed of Spindle 1) must

not be over the maximum speed range.

In the range where the rotating speed is high, the output torque of the

motor becomes small generally. For that set acceleration/deceleration

time constant at the Rigid Tap more largely than usually.

NOTE

When applying differential speed control to rigid tapping

(differential speed rigid tapping), ensure that the sum of the

speed specified for rigid tapping and that of the first spindle

does not exceed the maximum speed of the second spindle.

The output torque of a motor generally decreases in high

speed areas. So, a larger acceleration/deceleration time

constant must be set for rigid tapping.

For the method of rigid tapping, refer to the CNC manual.

Mounting Conditions

(a) Method of connection

and Notes

There are two methods of connecting an α position coder or

high-resolution position coder with the spindle.

(1) Connecting a position coder to the back of the spindle with a flexible

joint

This method conveys the rotation of the spindle precisely to the

position coder, so that the positioning precision of the position coder

is high. However, this method imposes a restriction on the location

of the installation. So, some modifications to the mechanical section

may become necessary.

(2) As shown below, fit the shaft for holding the pulley onto the shaft of

the position coder, and hold the shaft with double bearings. Thus, the

pulley of the position coder is connected to the pulley mounted on the

spindle via a timing belt.

α position coder or high-

Bearing

Key

resolution position coder

Pulley

Key

Shaft

Mounting plate

This connection method is generally used to connect a conventional

position coder to the spindle. When using this method, note the points

below.

1) If there is any play between the shaft for holding the pulley and the

shaft of the position coder, fretting can occur on the position coder

shaft, and the key can become loose, thus resulting in degraded

precision of the position coder positioning. So, fit the components

together accurately to ensure that there is no play between the position

coder shaft and shaft holding the pulley, or between the key and key

groove.

2) If the axis center of the position coder shaft is not aligned with the axis

center of the circumference of the position coder pulley, or if the axis

center of the spindle is not aligned with the axis center of the pulley

fitted onto the spindle, the positioning precision of the spindle

degrades in proportion to the magnitude of the eccentricity. So,

minimize these eccentricities.

562

B-65162E/03

12. DETECTORS FOR THE SPINDLE

(b) Shock

The position coders are precision detectors. So, be careful to protect

the position coders from shock.

The position coders conform to protection class IP55. However, this

class specifies short-term performance. So, ensure that the position

coders are not exposed to coolant or lubricant, and that oil does not

build up on the position coders. If a position coder is exposed to

coolant or lubricant, place a protection cover over the position coder.

NOTE

- Use the BZ sensor at temperatures not exceeding 80°C.

- The BZ sensor is a precision device. It must be handled with care. In particular, ensure that

no force is applied to the S section.

- The sensor is an electronic device. Provide dust and drip protection on the machine so that

the sensor is not exposed to chips, oil, water, or any other harmful substance.

- Those dimensions that are marked with an asterisk (*) are the dimensions of the sensor

mounting ring. Design a socket and spigot joint on the machine side to match the dimensions.

If a socket joint on the machine side is designed incorrectly, an incorrect signal may be output.

- The gap between the sensor and detection ring is adjusted beforehand. However, an output

signal may not satisfy the specified value due to a socket and spigot joint error. Check the

output signals when mounting a sensor. If an output signal does not satisfy a specified value,

adjust the gap. For information about the output signal level for gap adjustment, refer to Part

II of ”FANUC Built-in AC Spindle Motor α Series Descriptions (B-65202EN).”

- Make a shielded wire connection.

- To ensure ease of maintenance, install a sensor in a location where it can be replaced easily.

- The detection ring of a sensor can be exchanged with another sensor provided the sensors

have the same drawing number.

- A sensor and detection ring cannot be combined if the detection ring is designed for a drawing

number different from that of the sensor.

- A mating connector (accessory) is provided with the BZ sensor.

NOTE

Use the BZ sensor at temperatures not exceeding 80°C.

–

The BZ sensor is a precision device. It must be handled with care. In particular, ensure that

no force is applied to the S section.

The sensor is an electronic device. Provide dust and drip protection on the machine so that

the sensor is not exposed to chips, oil, water, or any other harmful substance.

When installing a BZ sensor, press it against the machine-side socket and spigot joint ( A in

size). (The machine-side socket and spigot joint is 4.5 mm high.) The gap between the sensor

and detection ring is adjusted beforehand. However, an output signal may not satisfy the

specified value due to a socket and spigot joint error. Check the output signals when mounting

a sensor. If an output signal does not satisfy the specified value, adjust the gap. For information

about the output signal level for gap adjustment, refer to Part II of ”FANUC Built-in AC Spindle

Motor α Series Descriptions (B-65202EN).”

To mount the BZ sensor, use screws of M4 x 20 mm and M4 x 25 mm.

–

Secure the cable at appropriate locations so that, when the cable is pulled, no force is directly

applied to the BZ sensor.

Make a shielded wire connection.

–

To ensure ease of maintenance, install a sensor in a location where the sensor can be replaced

easily.

The detection ring of a sensor can be exchanged with another sensor provided the sensors are

of the same drawing number.

A sensor cannot be combined with a detection ring if the detection ring is designed for a drawing

number different from that of the sensor.

(5) Mounting the BZ Sensor

Mount ring A and ring B as shown below.

D Press-fit the rings into the sleeve, then press-fit the sleeve into the spindle.

Ensure that ring A and ring B fit snugly.

D Ensure that a half point (9.3 mm) of the thickness of ring A plus ring B is

aligned with the center of the sensor within an error of

0.5 mm.

D Ensure that the fluctuation of the rings with respect to the sensor is within

0.03 mm.

D The fluctuation of the mounting ring with respect to the center of the shaft

is within

0.02 mm.

Value 22 applies to other

than T013 and T018.

NOTE

- From the table above, select the shrink fitting allowance that matches a maximum speed and

type of ring being used. If an incorrect allowance is employed, idle rotation or damage can

result.

- The rings cannot be used at a maximum speed that does not appear in the table above. For

the maximum allowable speed of each ring, see Item (C).
