Identification Label Derivative Electrical Specifications

Ratings

The size 1 to 4 drive is Heavy Duty rated only.

The size 5 to 8 drive is dual rated.

The setting of the motor rated current determines which rating applies -

Heavy Duty or Normal Duty

The two ratings are compatible with motors designed to IEC60034.

The graph aside illustrates the difference between Normal Duty and

Heavy Duty with respect to continuous current rating and short term overload limits.

Normal Duty Heavy Duty (default)

For applications which use Self ventilated (TENV/TEFC) induction motors and require a low overload capability, and full torque at low speeds is not required (e.g fans, pumps).

error code: 502

The speed at which the low speed protection takes effect can be changed by the setting of Low Speed Thermal Protection Mode

(04.025) The protection starts when the motor speed is below 15 % of base speed when Pr 04.025 = 0 (default) and below 50 % when

For constant torque applications or applications which require a high overload capability, or full torque is required at low speeds (e.g winders, hoists).

The thermal protection is set to protect force ventilated induction motors by default.

error code: 502

Motor I 2 t protection is fixed as shown below and is compatible with:

• Self ventilated (TENV/TEFC) induction motors

Motor I 2 t protection defaults to be compatible with:

2.2.1 Typical short term overload limits

error code: 502

Typical values are shown in the table below for RFC-A and open loop (OL) modes:

Generally the drive rated current is higher than the matching motor rated current allowing a higher level of overload than the default setting.

The time allowed in the overload region is proportionally reduced at very low output frequency on some drive ratings.

The maximum overload level which can be attained is independent of the speed

Operating mode RFC From cold RFC From 100 % Open loop from cold Open loop from 100 %

Normal Duty overload with motor rated current = drive rated current 110 % for 165 s 110 % for 9 s 110 % for 165 s 110 % for 9 s

Heavy Duty overload with motor rated current = drive rated current 180 % for 3 s 180 % for 3 s 150 % for 60 s 150 % for 8 s

Operating modes

The drive is designed to operate in any of the following modes:

error code: 502

Typically 100 % torque is available down to 1 Hz for a 50 Hz motor.

error code: 502

error code: 502

3 If the braking resistor is to be mounted inside the enclosure, add the average power figures from for each braking resistor that is to be installed in the enclosure

4 Calculate the total heat dissipation (in Watts) of any other equipment to be installed in the enclosure.

5 Add the heat dissipation figures obtained above This gives a figure in Watts for the total heat that will be dissipated inside the enclosure

Calculating the size of a sealed enclosure

error code: 502

Calculate the minimum required unobstructed surface area A e for the enclosure from:

A e Unobstructed surface area in m 2 (1 m 2 = 10.9 ft 2 )

T ext Maximum expected temperature in o C outside the enclosure

T int Maximum permissible temperature in o C inside the enclosure

P Power in Watts dissipated by all heat sources in the enclosure k Heat transmission coefficient of the enclosure material in W/m 2 / o C

To calculate the size of an enclosure for the following:

• Two drives operating at the Normal Duty rating

• External EMC filter for each drive

• Braking resistors are to be mounted outside the enclosure

• Maximum ambient temperature inside the enclosure: 40°C

• Maximum ambient temperature outside the enclosure: 30°C

For example, if the power dissipation from each drive is 187 W and the power dissipation from each external EMC filter is 9.2 W.

Power dissipation for the drives and the external EMC filters can be obtained from Chapter 12Technical dataon page 183.

The minimum required heat conducting area is then:

= 7.135 m 2 (77.8 ft 2 ) (1 m 2 = 10.9 ft 2 ) Estimate two of the enclosure dimensions - the height (H) and depth (D), for instance Calculate the width (W) from:

Inserting H = 2m and D = 0.6 m, obtain the minimum width:

If the enclosure is too large for the space available, it can be made smaller only by attending to one or all of the following:

• Using a lower PWM switching frequency to reduce the dissipation in the drives

• Reducing the ambient temperature outside the enclosure, and/or applying forced-air cooling to the outside of the enclosure

• Reducing the number of drives in the enclosure

• Removing other heat-generating equipment

Calculating the air-flow in a ventilated enclosure

The dimensions of the enclosure are required only for accommodating the equipment The equipment is cooled by the forced air flow.

Calculate the minimum required volume of ventilating air from:

V Air-flow in m 3 per hour (1 m 3 /hr = 0.59 ft 3 /min)

T ext Maximum expected temperature in°C outside the enclosure

T int Maximum permissible temperature in °C inside the enclosure

P Power in Watts dissipated by all heat sources in the enclosure

To calculate the size of an enclosure for the following:

• Three drives operating at the Normal Duty rating

• External EMC filter for each drive

• Braking resistors are to be mounted outside the enclosure

• Maximum ambient temperature inside the enclosure: 40 °C

• Maximum ambient temperature outside the enclosure: 30 °C

For example, dissipation of each drive: 101 W and dissipation of each external EMC filter: 6.9 W (max).

= 126.2 m 3 /hr (74.5 ft 3 /min) (1 m 3 / hr = 0.59 ft 3 /min)

Enclosure design and drive ambient

Drive derating is required for operation in high ambient temperatures

Totally enclosing or through panel mounting the drive in either a sealed cabinet (no airflow) or in a well ventilated cabinet makes a significant difference on drive cooling.

The chosen method affects the ambient temperature value (T rate ) which should be used for any necessary derating to ensure sufficient cooling for the whole of the drive

The ambient temperature for the four different combinations is defined below:

1 Totally enclosed with no air flow (2 m/s) over the drive

3 Through panel mounted with no airflow (2 m/s) over the drive

T rate = the greater of T ext or T int

T ext = Temperature outside the cabinet

T int = Temperature inside the cabinet

T rate = Temperature used to select current rating from tables in

Heatsink fan operation

The drive is ventilated by an internal heatsink fan The fan channels air through the heatsink chamber

AC supply requirements

690 V drive: 500 V to 690 V ±10 % Number of phases: 3

Maximum supply imbalance: 2 % negative phase sequence (equivalent to 3 % voltage imbalance between phases).

Frequency range: 48 to 62 Hz For UL compliance only, the maximum supply symmetrical fault current must be limited to 100 kA

All drives are suitable for use on any supply type i.e TN-S, TN-C-S, TT and IT.

• Supplies with voltage up to 600 V may have grounding at any potential, i.e neutral, centre or corner (“grounded delta”)

error code: 502

A ground fault in the supply has no effect in any case If the motor must

The ground loop impedance must conform to the requirements of local safety regulations

The drive must be grounded by a connection capable of carrying the prospective fault current until the protective device (fuse, etc.) disconnects the AC supply

The ground connections must be inspected and tested at appropriate intervals.

Input phase conductor size Minimum ground conductor size

≤ 10 mm 2 Either 10 mm 2 or two conductors of the same cross-sectional area as the input phase conductor.

> 10 mm 2 and ≤ 16 mm 2 The same cross-sectional area as the first input phase conductor.

> 35 mm 2 Half of the cross-sectional area of the input phase conductor.

Input line reactors reduce the risk of damage to the drive resulting from poor phase balance or severe disturbances on the supply network.

Where line reactors are to be used, reactance values of approximately 2

% are recommended Higher values may be used if necessary, but may result in a loss of drive output (reduced torque at high speed) because of the voltage drop.

For all drive ratings, 2 % line reactors permit drives to be used with a supply unbalance of up to 3.5 % negative phase sequence (equivalent to

Severe disturbances may be caused by the following factors, for example:

• Power factor correction equipment connected close to the drive.

• Large DC drives having no or inadequate line reactors connected to the supply.

• Across the line (DOL) started motor(s) connected to the supply such that when any of these motors are started, the voltage dip exceeds

error code: 502

Drives of low power rating may also be susceptible to disturbance when connected to supplies with a high rated capacity.

Line reactors are particularly recommended for use with the following drive models when one of the above factors exists, or when the supply capacity exceeds 175 kVA: Size 1 to 3

Model sizes 04200133 to 07600540 have an internal DC choke and

082001160 to 08600860 have internal AC line chokes so they do not require AC line reactors except for cases of excessive phase unbalance or extreme supply conditions.

When required, each drive must have its own reactor(s) Three individual reactors or a single three-phase reactor should be used.

The current rating of the line reactors should be as follows:

Not less than the continuous input current rating of the drive

Not less than twice the continuous input current rating of the drive

To calculate the inductance required (at Y%), use the following equation:

**These input reactors are not stocked by Control Techniques Contact your local Drive Centre.

The AC line reactors for the 110 V and other size drives should be sourced locally.

The reactance values will be higher than 2 % with some of these drives,

The 24 Vdc supply connected to the +24 V supply terminals on the AI-

Backup adaptor provides the following functions:

error code: 502

However, the drive will be in the Under Voltage state unless the line power supply is enabled, therefore diagnostics may not be possible

(Power down save parameters are not saved when using the 24 V back-up power supply input).

The working voltage range of the 24 V back-up power supply is as follows:

Minimum and maximum voltage values include ripple and noise Ripple and noise values must not exceed 5 %.
