or equivalent to LMFC manufactured by The

Furukawa Electric Co., Ltd.

The cross-section area of each cable is determined

under the following conditions:

(1) At SVPM rated output

(2) Environment temperature of cable : 30°C

(3) Number of harnesses

3 (No current flows through the ground wire

during normal operation.)

The required cross-section area of a cable varies

depending on the environment and requirements of

the user. Select an appropriate cable size.

WARNING

Defects, such as a loose screw, an incorrectly

inserted connector, and a poorly crimped terminal,

can lead to a motor malfunction, excessive heat

generation, and a ground fault. Exercise

adequate care in installing servo amplifiers.

A loose screw and a poorly crimped terminal (or, if

a connector is used, a loose connector contact or

an incorrect connector pin-to-cable connection) on

high-current carrying power supply wires or motor

power wires can lead to fire. Exercise adequate

care in wiring.

When the contact is ON (closed), the spindle motor and servo

motor are enabled.

When the contact is OFF (open), the external magnetic contactor

(MCC) is in the off state, and the spindle motor and servo motor

do not operate.

(2)

When the contact is set to OFF (open) during motor rotation, the

spindle motor decelerates, then stops, and the servo motor is

stopped by the dynamic brake.

(3)

The contact input signal is specified as follows:

<1> As the external contact capacity, a voltage of at least 30

VDC and a current of at least 100 mA are required.

<2> Significant levels

(with the voltage between input pins)

when the contactless signal input mode is used:

Low level "logic 0": Up to 2 V

High level "logic 1": At least 20 V

(4)

When the SVPM main power is turned off for safety in such a

case that the machine protection door is open, the contact of the

ESP signal (CX4), which is input to the SVPM, must be set to

OFF (open) within 200 ms after turn-off of the SVPM main

power.

When the contact of the ESP signal (CX4) remains ON (closed)

after the SVPM main power is turned off, a DC link low-voltage

alarm occurs in the SVPM.

1 The +5V pin is intended for optical link transmission

2 SVPM serial interface connection using an optical

fiber cable

The use of an optical I/O link adapter with the SVPM

serial interface extends the maximum allowable

length of the optical fiber cable to up to 200 m.

Use optical fiber cables in the following cases:

• When the required cable length is 20 m or longer.

• When the cable must be extended across multiple

cabinets, and the cabinets cannot be connected

with a grounding wire 5.5 mm² or larger.

• The cable may be affected by noise, for example,

if the cable is laid near a strong magnetic noise

source like a welding machine or in parallel with a

power line over a long distance.

20-pin half-pitch connector

Manufactured by tyco Electronics AMP

Housing : 178289-6

Contact : 1-175217-2

Cable specification : 6 common shielded cable

(Four 0.18mm² twisted pairs + 0.5mm² wires)

Recommended cable conductor : A66L-0001-0368

See Section 5.4.1 for explanations about the JYA2-side connector that

matches the recommended cable.

NOTE

If only one 5V line and only one 0V line are used,

use pins 20 and 16 for them, so that, if the

connector is attached the wrong way, the sensor

can be prevented from being damaged.

NOTE

1 Select such an external resistance such that

VR+R1 falls within the range between 2 kΩ and 10

kΩ .

2 No LM output is included in the #C specification.

For the SM output, select the load meter or

speedometer by parameter setting.

NOTE

Pins indicated # are intended to input or output

signals used on a spindle check board. Do not

connect any other signal line to them.

Voltage signal for the speedometer (SM)

By externally connecting a tachometer, the speed of the spindle motor

can be indicated. The voltage (DC) proportional to the speed (for the

#C specification, an estimated speed) is output, regardless of the

rotation direction of the motor. At the maximum motor speed, +10 V

is output.

The output voltage of the speedometer in the forward direction and

reverse direction is calibrated using a parameter. The precision is ±3%

Max.

Voltage signal for the load meter (LM)

The load meter indicates the percentage of the load to the maximum

motor output

(load ratio). A voltage of

10 V is output at the

maximum output.

NOTE

1 The vertical axis represents the motor speed. If

the spindle-to-motor speed ratio is not 1:1, it is

recommended to convert the motor speed to the

spindle speed.

2 The precision of load meter voltage depends on the

used speed and input voltage. The maximum error

is about ±15%.
