MD-AX520-5.0K, 7.0K Instruction Manual Supplement This Instruction Manual Supplement provides the dedicated specification for the magnet motor drive unit MD-AX520-5.0K and 7.0K. For the information not found in this Instruction Manual Supplement, please refer to the Instruction Manual of the MD-AX520 series.

1. Drive units to be used with motors Refer to: Chapter 1 of the Specifications/Instruction Manual, 1.1.3 Drive units to

be used with motors Use the drive units and motors in the following combinations. (The drive unit and motor of the same capacity are used together.)

Drive Unit Motor MD-AX520-0.5K MM-CF52 MD-AX520-1.0K MM-CF102 MD-AX520-1.5K MM-CF152 MD-AX520-2.0K MM-CF202 MD-AX520-3.5K MM-CF352 MD-AX520-5.0K MM-CF502 MD-AX520-7.0K MM-CF702

2. Installation in control box

Refer to: Chapter 2 of the Specifications/Instruction Manual, 2.1.2 Installation in control box

When installing the drive unit in a control box, the internal temperature of the control box must not exceed the permissible value due to drive-unit generated heat and peripheral-generated heat. Placing a heat sink outside the control box can reduce the heat generated inside the control box Refer to: Chapter 7 of the Specifications/Instruction Manual, 7.1.3 Option

NOTICE

Leave the specified clearances between the drive unit and control box walls or other equipment. Not doing so can cause a failure. In addition, improper convection of air in the control box will reduce the heat dissipation effect. Fully consider the equipment layout in the control box and the use of a cooling fan for ventilation, for example.

1cm or more for 3.5K or less. These clearances are also required for replacement of the cooling fan.

Leave sufficient clearances above and under the drive unit to ensure adequate ventilation.

Installation in enclosed control box The following is the relationship between the internal temperature rise and heat dissipation area of an enclosed control box (hereafter referred to as the enclosure) which accommodates the drive unit.

P A = K T

A: Heat dissipation area (m2) P: All losses produced in enclosure (W) T: Difference between enclosure inside and outside-air temperatures (C) K: Heat dissipation factor

The heat dissipation area A does not include the area in contact with a structures which interfere with heat dissipation, e.g. floor and walls. The heat dissipation factor K used is normally 5 to 6, which depends on the enclosure structure, the layout of parts in the enclosure, and the outside-air temperature.

Produced losses The following table indicates the losses produced during rated load operation of the drive unit.

NOTICE

Choose the size of the wires connected to the motor connection terminals so that a voltage drop due to the wires is less than 4V. The minimum wire size in the above selection table assumes that the wiring length is less than 20m. A voltage drop can be found by the following expression: Line voltage drop (mV) = 3 wire resistance (/km) wiring length (m) current (A)

Use the ground cable which is as thick as possible. We recommend you to use the 0.75mm2 or less wire size for the control circuit terminals. Using the wire size of 1.25mm2 or more may cause the front cover to bulge, leading to a contact fault in the operation panel or parameter unit, when there are many cables wired, for example.

NOTICE

Select the no-fuse breaker according to the power supply capacity. Install one no-fuse breaker per drive unit. When the breaker on the drive unit primary side trips, check for the wiring fault (short circuit), damage to internal parts of the drive unit, etc. Identify the cause of the trip, then remove the cause and power on the breaker.

(4) Earth leakage circuit breakers

Selection method Use the earth leakage circuit breaker which has harmonic/surge suppression. Our product: Progressive Super Series NV-SF, NV-CF

MEMO

Leakage currents from the wiring and motor include frequency components of a higher degrees than those from the commercial power supply. Therefore, the earth leakage circuit breaker which is not a harmonic/surge suppression product can cause unnecessary operations. Minimize the wiring distance of I/O cables. Run I/O cables away (more than 30cm) from the earth. Reduce the Pr. 72 "motor tone selection" setting.

5. Wiring of the control circuit power supply terminals R1, S1

Refer to: Chapter 3 of the Specifications/Instruction Manual, 3.2.4 Wiring of the control circuit power supply terminals R1, S1

Wire these terminals when you want to supply the control circuit power of the drive unit to retain the alarm signal if the magnetic contactor (MC) on the power supply side is opened to switch off main circuit power when the protective circuit is activated.

1) Remove the jumpers across the terminals R-R1, S-S1. 2) Wire the terminals R1, S1 from the primary side of the magnetic contactor.

MD-AX520-0.5K to 3.5K MD-AX520-5.0K, 7.0K

control circuit to the upper

terminals (R1, S1).

MEMO An error display (E.OC1) will be provided if you turn on the start signal with power supplied to only the R1 and S1 terminals.

CAUTION

When you have energized the AC power input terminals R, S, T, always energize the control circuit power supply terminals R1, S1, too. The drive unit may be damaged if you energize the AC power input terminals without the control circuit power supply terminals being energized.

Before wiring the control circuit power supply terminals, always remove the jumpers across the terminals R-R1 and across the terminals S-S1. Not doing so can cause a power supply short circuit.

When using MD-AX520-5.0K and 7.0K, connecting the power supply cable to the lower terminals may break the drive unit. Do not connect the power supply cable to those terminals.
