4.4 WIRING INSTRUCTIONS

Complete VS-626MTIII interconnections, follo~ving the instructions given below.

(1) Control signal leads ( lCN to 3CN) must be separated from main circuit leads

(.R, S, T, U, V, W) and other power lines and power supply lines to prevent erro-

neous operation caused by noise interference .

(2) Use the twisted shielded lead for the control signal line, and connect the shield s heath to any of the controller terminals . the wiring distance of the signal leads be 20 meters or below.

See Fig. 4.2.

It is recommended that

SHIELD SHEATH

TO SH

Fig. 4.2 Shielded Lead Termination

(3) Make a positive grounding using ground terminal E on the casing of VS-626MTIE.

. Ground resistance should be 1000 or less .

. Never ground VS-626MTIII in common with welding machines , motors , and other

large-current electrical equipment , or

separate conduit from leads for large–current electrical equipment. 0 Use ground lead listed in Table 4.4 and make the length as short as possible. . Even when VS-626MTIII is grounded through its mountings such as channel base

or steel plate, be sure to ground VS-626MTJII using the ground terminal E.

. Where several VS-626MTIII units are used side by side, all the units should pre-

ferably be grounded directly to the grouncl poles . However, connecting all the

ground terminals of VS-626MTID in parallel,

to the ground pole is also permissible (Fig, 4. 3) . However, do not form a lC)OP with the ground leads ,

Never connect power factor correction capacitor

Fig, 4.5 Removal of Power Factor Correction Capacitor

(9) When applying a ground fault interrupter or relay, it should have good balance

characteristics and be connected on the power supply side as shown in Fig. 4.6.

Since the output from the VS-626MTlIl controller contains higher-level harmonic

components , a zero–phase current flows through the stray capacitor (Cl) of the

10.4 OPERATION

After checking with power on ,

supply a running signal to operate.

Gradually increasing the speed reference from O% starts the motor. Check that the direction c,f motor rotation is proper.

The proper direction is counterclockwise as viewed from the motor shaft end when forward run signal (FORRN) is closed and the speed reference has a positive polarity.

A wrong phase sequence of the power cable between VS-626MTIII controller

and motor or the PG signal can be considered if the direction of rotation is reverse, cr if the motor creates excessive noise or vibrates, cperation.

Turn off the power and check the wiring.

without rotating,

Check that the motor smoothly accelerates and decelerates in both forward

and reverse directions by changing the speed reference, At the same time, check

that the motor is not vibrating or emitting noise excessively. The sound of the

motor constantly audible at several thousand hertz is caused by the control system

and presents no problem.

during

CAUTION

● Start the motor after confirming that the motor is completely stopped, If the

motor is started during coasting, overvoltage (OV) or overcurrent (OC) may occur.

● Do not turn on MCCB in the VS-626MTIJI controller after turning on the power.

Tripping may occur due to the charging current to capacitors.

This is used for adjustment of loop gain of speed control system. The five constants listed above can be adjusted respectively, depending on the operation mode. The closer the setting is brought to O, but the response becomes slower.

the lower and more stable the gain becomes,

The larger the setting is adjusted, the quicker

becomes the response, but the control system tends to become unstable. Adjust

it to the optimum gain , taking into consideration the load conditions .

Adjusting range of the constants is as follows :

Features of Winding Selection

Winding Selection method is an effective way to expand the constant power range of spindle drives.

This method has features as below.

(”[) Wide Range Constant power

Wide range constant power, gears.

(2) Small Inverter Capacity

with a ratio of 1: 12, is available without

A larger size inverter is required to expand the constant power range with

an ordinary methods because motor current increases at low speed range.

In this method, a standard size inverter is available to expand a constant

power range.

High Control Stability

(:3 )

W’inding selection method has both a low speed winding and high speed

winding. stability increases as high loop gain can be used.

(4) Magnetic Contactor for Winding Selection.

This magnetic contactor was developed for winding selection and the size

is small.

can be directly driven by the inverter. 5 millions contacts.

Each winding is used in each speed range. Therefore, control

The contact arrangement of this contactor is transfer type and it

18.2 AC SPINDLE MOTOR MOUNTING CONDITIONS

When mounting the AC main spindle motor, observe the following:

( 1) Mounting Location

. Ensure that there is adequate air flow to and from the cooling fan. Provide at least

100 mm space on the motor rear (exhaust side)

. Ensure that no cutting fluid splashes directly on the motor

Ensure that the bed, foundation and base,

addition to the motor weight,

are sufficiently sturdy to prevent vibration.

which are subject to dynamic loads,

(2) IVIounting orientation

. Mount the motor on the floor with the foot down.

(3) I,inking with machine

To install belts, align the motor shaft and machine shaft parallel, and

shafts perpendicular to the line connecting the two pulleys.

“ Since the motor runs at high speeds,

even a slight imbalance causes vibration. Be

sure to balance the pulley, etc. carefully.

21.4 NOTES

If the magnetic contactor for motor winding selection is damaged or the

signal leads are disconnected, the spindle stops and operation program

does not proceed. Check time and output alarm signal by using motor winding selection signal and motor winding selection completion signal to inform worker of this

condition.

The frequency of operation of magnetic contactor for motor winding selection increases with this method, because motor winding is switched whenever

actual motor speed exceeds

Automatic winding selection is performed when the selection speed is reach-

ed even during cutting.

NCNG \Vhich is threshold speed.

As shown in Fig.

21.7, some roughness is seen in rough-cutting, however, the closer to finishing, the smaller the error becomes. Therefore, sufficient characteristics can be obtained for actual application. lVhen further accuracy is required, check cutting face accuracy.

Magnetic Sensor Type Spindle Orientation

Magnetic sensor type spindle orientation system is used to stop the machine tool

spindle at a specified position by an electrical method. This system has the follow–

features:

in g

(1)

Simple mechanism

The spindle specified position stop functions are accomplished just by mounting a magnetic unit on the spindle and a magnetic sensor on the stationary member.

(~)

Short orientation time

The position detection signal from the magnetic sensor forms a servo loop for accurate positioning in a short period of time even when the spindle is running at maximum speed.

Reliability and service life improvement

(3)

Substantial reduction of positioning shock leads to higher reliability and longer service life .

Economical advantage

(4)

Simplified mechanism and power control sequence make for substantial reduc-

tion in cost.

26.2 ORIENTATION OPERATION

The VS-626MTIII has two operating modes:

the normal mode in which the spindle is controlled by external orientation signals, and the test mode in which the spindle i:; controlled by card test signals for adjustment.

26.2.1 Normal Mode

When an orientation signal is received while the spindle is in motion (or standing

still) , the spindle immediately decelerates (or accelerates) to the preset orientation

speed.

When the spindle passes the target stop position first time after attaining the preset speed, the soft start function incorporated in the orientation card is started, and the spindle

then, as the magneto comes into alignment with the magnetic sensor,

by the servo loop.

Thereupon, the O-END LED (green) lights, and an
