Varispeed-626MTIII Drives

AC ADJUSTABLE SPEED DRIVES FOR MACHINE TOOL SPINDLES

3.7 TO 30 kW (5 TO 40 HP), 30-MINUTE OPERATION RATING

2.2 TO 22 kW (3 TO 60 HP), CONTINUOUS OPERATION RATING

Varispeed-626MTlll Drives (VS-626MTIU ) are highly reliable adjustable speed

AC spindle motor drives for NC machine tools. VS-626MTIII drives combine a compact, high speed AC spindle drive motor with a digital vectorcontrolled, high performance transistor inverter (controller).

The VS-626MTIU drives achieve high speed operation and heavy duty machining even while operating under adverse environmental conditions. The VS-626MTIII is an ideal spindle drive for machining centers, lathes, milling machines, etc.

The features of the VS-626MTIU are as follows:

● 8000 r/rein max and constant power range (1 : 5.3) (for 7.5kW or below)

● Constant power (1

● Enhanced performance through digital vector control

● Compact and lightweight

● Low vibration/low noise operation

● Improved machining due to unique motor cooling system

● Reliable functions for improved maintenability

1.3 PROTECTION FUNCTIONS

In case a malfunction occurs during operation,

the malfunction state is displayed by the LEDs of the setting panel according to the malfunction], as shown in Table 1.4, and operation puts on hold. In case multiple malfunctions occur, Lhe malfunctions are recorded in the order they occurred. This will be useful for analysis of the cause of malfunction.

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

cable between VS–626,MTIII controller and motor or through the stray capacitor

( c2) of the motor, sometimes resulting in erroneous operation of the ground fault interrupter. ing:
