10.HEAT DISSIPATION

SVPM

B-65322EN/02

10

HEAT DISSIPATION

The amount of heat generated in an SVPM varies depending on its

model, the current flowing through the motor, and the motor output.

(Refer to the respective motor description manuals for the current and

output of each motor.)

(1) Total amount of heat dissipation

The total amount of heat dissipation by the SVPM is calculated

according to the following expression:

Total amount of heat dissipation

= a + Ka1×b1 + Ka2×b2 + Ka3×b3 + Ka4×b4 + Ka5×b5

a

: Amount of heat dissipation determined by the SVPM

model [W]

By placing the heat sink section of the SVPM outside the cabinet,

the residual amount of heat in the cabinet can be calculated

according to the expression below.

11.POWER CABLE FOR SERVO MOTOR AND AMPLIFIER SVPM

B-65322EN/02

11.1 SELECTING A POWER CABLE

Select the cable specification by considering the following conditions

for use:

<1> Motor current rating or current needed in use on a real machine

<2> Cable type (heat resistance temperature, etc.)

<3> Environment in which the cable is installed (operating ambient

temperature, etc.)

<4> Need of water proofing (pay attention to the diameter of the

applicable cable clamp)

<5> Certification for CE marking (compliance with various safety

standards and EMC standard)

<6> Insulation distance between the cable and terminal is secured at

the time of wiring.

Examples of selecting a heavy-duty power cable are shown below.

Fully check the cable specifications based on the actual use conditions

and use an example below.

The cable diameters are determined based on JCS No. 168 D (1980),

"Allowable Currents for Power Cables (1)."

INPUT POWER SUPPLY

5.1.1

Three-phase Input Power Supply for Motor Power

See Subsection 5.1.1 “Three-phase Input Power Supply for Motor

Power” in Part I.

5.1.2

Single-phase Input Power Supply for Motor Power

See Subsection 5.1.2 “Single-phase Input Power Supply for Motor

Power" in Part I.

5.1.3

Control Power

Be sure to use a stabilized power supply as the 24-V power supply for

the βi SVM. The 24-V power supply for motor brakes cannot be

shared.

-

Nominal rated voltage: 24VDC

-

Allowable voltage fluctuation:

±10% (including momentary variations and ripples)

-

Power supply rating:

0.9 A (per βi SVM unit)

5.1.3.1

Sequence for turning on control power supply

Turn on the control power supply of the βi SVM at the same time

when the power to the host controller connected via the I/O Link is

turned on or before the host controller is turned on. When turning

off the power to the host controller, be sure to also turn off the control

power supply of the βi SVM.
