Installation tolerances

Setting up MOVIMOT

MOVIMOT® may not be installed unless:

• the entries on the name plate of the drive match the mains power supply,

• the drive is undamaged (no damage caused by transport or storage) and

• it is certain that the following requirements have been fulfilled: – ambient temperatures between -20 °C and +40 °C (remember that the tempera-

ture range of the gear unit may be restricted → operating instructions for the

gear unit), – no oil, acid, gas, vapors, radiation, etc., – installation altitude max. 1000 m above sea level.

Shaft end Flanges

Diametric tolerance in accordance with DIN 748

• ISO k6 at ∅ ≤ 50 mm

• ISO m6 at ∅ > 50 mm (Center hole in accordance with DIN 332, shape DR)

→ ”MOVIMOT® Geared Motors” catalog, section ”Notes on Dimension Sheets.”

Centering shoulder tolerance in accordance with DIN 42948

• ISO j6 at ∅ ≤ 230 mm

• ISO h6 at ∅ > 230 mm

The MOVIMOT® may only be mounted or installed in the specified mounting position on a level, vibration-proof and torsionally rigid support structure.

• Thoroughly remove anti-corrosion agents from the shaft ends (use a commercially available solvent). Do not allow the solvent to penetrate the bearings and shaft seals – this could cause material damage!

• Carefully align MOVIMOT

and the driven machine to avoid placing any unacceptable strain on the motor shafts (observe permissible overhung load and axial thrust data!).

• Do not butt or hammer the shaft end.

• Use an appropriate cover to protect motors in vertical mounting positions from accidental entering of objects or fluids ! (Protection cowl C)

• Ensure an unobstructed cooling air supply and that air heated by other units cannot be drawn in or reused.

• Balance components for subsequent mounting on the shaft with a half key (output shafts are balanced with a half key).

• The rated voltage and frequency of MOVIMOT® must correspond to the data for the

mains supply.

Installation guidelines

Selecting the cables

Permitted line cross section of the terminals

Conductor end sleeves

Cable entries

Line protection

Residual-currentoperated circuit breaker

Contactor switch contacts

• The cross sections of the cables used must be selected according to the rated current of the unit and the applicable installation regulations.

• The selection of the cable type is based on the applicable installation regulations and the requirements at the application location.

Power terminals Control terminals

1.0 mm2 – 4.0 mm2 (2 x 4.0 mm2) 0.25 mm2 – 1.0 mm2 (2 x 0.75 mm2) AWG17 – AWG10 (2 x AWG10) AWG22 – AWG17 (2 x AWG18)

• Use conductor end sleeves without insulating shrouds (DIN 46228 part 1, material E-CU)

• All cable entries are supplied fitted with a closing plug. To connect the unit, replac e the req uired nu mbe r of plug s with su itable cable entries which are fitted with strain relief.

• The cable entries must meet the requirements of EN 50 014, 2nd edition.

• Select the cable entries on the basis of the diameter of the cables used. Please refer to the documentation provided by the manufacturer of the cable entry for further information.

• Install the line protection at the start of the supply system lead behind the supply bus junction ( breakers. The fusible rating should be selected in accordance with the cross section of the cable.

• It is not permissible to use a conventional residual-current-operated circuit breaker (r.c.c.b.) as a protective device. Universal current-sensitive residual-current-operated circuit breakers (tripping current 300 mA) are permissible as a protective device. Earth-leakage currents > 3.5 mA may occur during normal operation of the MOVIMOT

• Contactor switch contacts in utilization category AC-3 to IEC 158 must be used for switching MOVIMOT

supply

• SEW recommends using earth-leakage monitors with a pulse code measuring process in voltage power systems with a non-earthed star point (IT systems). This avoids faulty tripping of the earth-leakage monitor due to the earth capacitance of the inverter.

• The MOVIMOT® power supply should be either from an external 24 VDC voltage or

using the MLA12A options.

• Connect the required electronic control leads (e.g. CW/STOP, CCW/STOP, setpoint changeover f1/f2).

• Use shielded cables as control leads and route them separately from power current cables.

With PLC bus master or MLA12A option

• Important: Only ever connect one

• Use twisted pair shielded cables as control leads and route them separately fro m power current cables.

• All cable entries which are not required must be sealed properly using suitable closing plugs.

Operating Instructions MOVIMOT® MM..B for Use According to Category 3D

5.2 Protection concept

In order to avoid exceeding the permitted temperature, only operation in accor-

dance with the operating characteristics is permitted (see “Operating characteristics” on page 38)!

• MOVIMOT® units in category 3D are supplied with a temperature switch (TH). The

TH switches off the motor if the winding temperature exceeds the maximum value.

• The switching off process by the TH must be monitored by an independent evaluation unit.

• The independent evaluation unit must be equipped with a base insulation to securely separated electrical circuits.

• The drive must be disconnected from the supply power system when the TH trips.

• The TH automatically switches itself back on when the temperature drops below the maximum value! A restart interlock must prevent the drive from being energized. Important: Do not switch the drive back on until the cause of the problem has been

checked. This check must be performed by a trained specialist.

Protection concept

In conjunction with MLA12A

• The unit is supplied with the TH already wired up in conjunction with MLA12A. Consequently, the 24 V power supply of MOVIMOT and the drive is stopped. At the same time, the ready contact of the MOVIMOT drops out (ready signal terminals). A restart interlock must prevent the drive

from being energized again automatically when the TH switches back on. Important: Do not switch the drive back on until the cause of the problem has been

checked. This check must be performed by a trained specialist.

5.3 Operating modes

The following operating modes are permitted with MOVIMOT® units in category 3D:

4Q operation

1Q operation

1. 4Q operation with motors with a mechanical brake

• The brake coil is used as a braking resistor in 4Q operation.

• No external braking resistor is allowed to be connected.

• Regenerative load capacity of the brake coil

2. 1Q operation with motors without a mechanical brake

Important:

Connecting an internal or external braking resistor is not permitted!

• The TH switch-off must be monitored by an independent eval uation unit.

• The drive must be disconnected from the power suuply system when the TH trips.

• The TH automatically switches itself back on when the temperature drops below the maximum value! An automatic restart must be prevented (restart interlock).

• Do not switch the drive back on until the cause of the problem has been checked. This check must be performed by a trained specialist.

Functional check

Check proper brake function when brake motors are used. This step will prevent brake friction and the associated generation of excess heat.

Inspection and maintenance periods

8 Inspection and Maintenance

Notes:

• Only use genuine spare parts in accordance with the valid spare parts list!

• Important – Danger of burns: Motors can become very hot during operation!

• The IP enclosure of the housing must be maintained in order to ensure protection against explosions. It is therefore very important to make sure that the housing parts are assembled correctly in accordance with the spare parts list for all maintenance and inspection work. Elastomer and plastic seals must be replaced with genuine spare parts.

8.1 Inspection and maintenance periods

Brake

What to do?

• Inspect the brake (working air gap, brake disk, pressure plate, carrier / gearing, pressure rings)

• Remove abraded matter

• Inspect the moto r (fit new ball bearings/oil seal)

• Clean the cooling air passages

• Touch up or renew the anticorrosion coating

Checks following maintenance or repair work

Perform a safety and functional check after all maintenance or repair work. This check should be the same as the functional check described for startup.

Perform another routine test prior to startup if you have rep laced any parts on the m otor which may affect its explosion-proof qualities.

Inspection and maintenance of the brake

8.3 Inspection and maintenance of the brake

Parts of the brake are subject to wear during operation. As a result, regular inspection and maintenance are essential.

Using the brake as a working brake

Using the brake as a holding brake

If the brake is used as a working brake, the brake pad wear is the determining factor governing when to service the brake.

Do not allow the maximum permitted working air gap to be exceeded (see “Work done until adjustment, working air gap, braking torque of brake” on page 37). The inspection and maintenance intervals can be calculated on the basis of the work done by the brake in each braking operation and the entire work done until adjustment (see “Work done until adjustment, working air gap, braking torque of brake” on page 37).

To do this, please calculate the work do ne in ea ch brak ing opera tion indiv idually in a ccordance with the project planning documents. Check the brake at the latest when it has performed the amount of work until reset at which point an adjustment is due.

The following parts of the brake are subject to wear and should be r eplaced if necessary (see Fig. 4):

• Brake disk (7)

• Annular spring (6)

• Pressure plate (8)

• Pressure rings and counter springs (10 b, c)

• Brake springs (11)

• Also replace the self-locking hexagon nuts (10e) and the rubber sealing collar (5)

after repeated disassembly/assembly.

Brakes used as holding brakes are only subject to a small amount of lining wear. However, their mechanical transmission elements must also be checked for wear.
