NOTE

Single phase can be obtained from a 3 phase "wye" by wiring two of the "hots" (L1 and L2 or L2 and L3 or L1 and L3) to the single phase control. Power supplied to the drive must be from a balanced power supply with an earth ground. A floating ground or an unbalanced supply can permanently damage the drive.

1.3 Safety

Read Chapter 2 Safety Information before mounting or wiring the drive.

The STOP and START controls or electrical inputs of the drive must not be relied upon to ensure the safety of the personnel. They do not isolate dangerous voltages from the output of the drive or from any external unit. The supply must be disconnected by an approved electrical isolation device before gaining access to electrical connections. The drive contains capacitors that remain charged to a potentially lethal voltage after AC supply has been disconnected. Wait at least 10 minutes for the stored charge to

dissipate. See section 2.9.4 Stored charge .

1.4 Mounting of Drive

The drive is designed to mount to a wall within a control panel or on a DIN rail. For proper functioning, mount the drive with the minimum recommended clearances. See Chapter 4.

1.5 Wiring Motor

The IMC high performance motor can be wired as either 200 or 400 volts. Wire the motor as 200V for the A Size IM-pAC and wire the motor as 400V for the B Size IMpAC. See section 5.1, Figure 5-1 and Figure 5-2.

1.7 Wiring Power and Switches to Drive

1. Refer to Chapter 3 Rating Datafor all other fuse sizes and control and motor cable

wire sizes. Single phase can be obtained from a 3 phase "wye" by wiring two of the "hots" (L1 and L2 or L2 and L3 or L1 and L3) to the drive. Do not remove internal EMC filter. See Chapter 5.

2. The control terminal B2 outputs 24 volts DC and will be used to power the signals. The control terminal B4 is used to enable the drive. As long as B2 and B4 are connected the drive will run. Use a normally closed switch (not supplied by IMC) or jumper between B2 and B4 to enable the drive. The control terminal B5 runs the motor forward and B6 runs the motor in reverse. If the indexer is not turning in the proper direction interchange B5 and B6.

3. Make sure the indexer is in the middle of its dwell position before starting or

stopping the motor. see section 1.16 Indexer drive shown in middle of dwell position diagram. on page 9.

4. The motor is made to run by closing the B2-B5 or B2-B6 terminals. Opening them will stop the motor.

5. Cycling on demand using a limit switch and inverter duty motor. The normally closed side of the cam shaft limit switch should be wired to terminals B2 and B5 (or B6). When the indexer is in dwell the switch will be open. A start signal is sent by momentarily closing B2 and B5 with an external switch. As the camshaft is turning the limit switch on the cam shaft will close and thus maintain the B2-B5 (or B6) closure. When the indexer enters dwell the trip cam on the cam shaft will cause the

1.24 How to configure the IM-pAC drive to trip for a current ove r-

WARNING

load.

The current overload configuration will protect the index drive only and is not meant to be a means of protecting any personnel or tooling. Always make sure that no person is near the indexer and the indexer is clear of any obstructions before operating the drive while testing the configuration settings or during normal operation.

Overview

The IM-pAC drive is factory preset to constantly monitor the current seen by the motor and the drive will trip if the accumulated motor current values over time exceed a set value. This is a calculation and does not require a wired motor themistor input.

The motor thermal constant parameter controls the drive trip and is set at a default value of 89. The 89 value will allow the motor to draw 1.65 times its rated amperage for a little over 40 seconds before the drive will trip. When the drive trips the drive healthy relay (T5 and T6 contacts) will open to signal the trip. You will wire your PLC input line through the drive healthy relay to signal the trip. When the drive is tripped the display will show [It.AC]

The overload configuration scheme for the IM-pAC uses a thermal constant parameter set to 1 (the minimum) and a symmetrical current value set for the application. Index drives 601RDM and 902RDM have been tested at IMC using a thermal constant of 1 and a symmetrical current constant of 165. The drives successfully tripped without any indexer damage for a jammed dwell or an obstruction encountered during the middle of the index.

For now based upon our test results we are limiting use of this overload configuration to applications under 1 horsepower demand.

The following steps describe how to view the torque required for you application and how to change the symmetrical current and motor constant values to protect your indexer from damage.

We are assuming that you have already entered in the correct parameter values for Pr 39, Pr 06, Pr 08 and Pr 09 from your motor name plate.

We also assume you have placed the jumpers and wired your motor for the correct applied voltage. Remember the control voltage must be greater than or equal to the motor's voltage.

The instructions in this document are detailed and should be read carefully before proceeding. In addition we have included as a reference on the last page of this paper a page from the IM-pAC manual showing how to view and change parameters from the keypad.

Parameters Used

Parameter Description Pr 10 Security level - default is L1 Pr 88 Current magnitude - current demand for your application Pr 4.07 Symmetrical current value - default is 165 percent Pr 4.15 Motor thermal constant - default is 89

The key pad display should show [ih 0.0] and not [rd 0.0] when you start. You must put the control into inhibit mode by opening B2 and B4.

Page 23

Step 1 - Changing the security level.

Press the M (memory) button on the key pad. The display will start to show the flashing parameter numbers on the left side and the non-flashing parameter values on the right side. Now, press the /\ button to the right of the M button several time until the left parameter value changes to 10. If you happen to go passed Pr 10 then use the \/ key to return to Pr 10. Once you are at the flashing Pr 10, press the M key and the parameter value on the right L1 should start to flash.

Press the /\ key 2 times until a value of L3 appears [10 L3].

Press the M key 2 times to return the display back to [ih 0.0].

Step 2 - How to map the motor thermal constant to Pr 61.

Press the M button on the key pad. Now, press the \/ button until the left parameter value changes to Pr 71. If you happen to go passed Pr 71, then use the /\ key to return to Pr 71. Once you are at the flashing Pr 71, press the M key and the parameter value on the right 0.0 should start to flash.

Press the /\ key several times until a value of 4.15 appears [71 4.15].

Press the M key 2 times to return the display back to the [ih 0.0].

Step 3 - How to map the symmetrical current value to Pr 62.

Press the M button on the key pad. Now, press the \/ button until the left parameter value changes to Pr 72. If you happen to go passed Pr 72, then use the /\ key to return to Pr 72. Once you are at the flashing Pr 72, press the M key and the parameter value on the right 0.0 should start to flash.

Press the /\ key several times until a value of 4.07 appears [72 4.07].

Press the M key 2 times to return the display back to [ih 0.0].

Step 4 - How to view the current magnitude for your application.

See the Safety Warning on the first page before continuing.

The key pad display should show [rd 0.0] when you start. If the display shows [ih 0.0] you must take the control out of inhibit mode by closing B2 and B4. Make sure you are set to run at your intended speed and load. You will now run the motor continuously in order to view and record the maximum current demand for your application. In order to run the motor continuously you must keep connection B2 and B5 closed. You can do this with a simple jumper. Once the motor and drive are running, press the M button on the key pad. Now, press the \/ button until the left parameter value changes to Pr 88. If you happen to go passed Pr 88, then use the /\ key to return to Pr 88. The maximum value for Pr 88 is the maximum value for your application. You will use this amperage value in step 6 as part of a calculation for the symmetrical current value.

Press the M key 2 times to return the display back to the [rd 0.0].

You can now remove the jumper between B2 and B5.

Step 5 - How to change the motor thermal constant Pr 61.

Press the M button on the key pad. Now, press the \/ button several times until the left parameter value changes to Pr 61. If you happen to go passed Pr 61, then use the /\ key to return to Pr 61. Once you are at the flashing Pr 61, press the M key and the parameter value on the right Pr 89 should start to flash.

Press the \/ key several times until a value of 1 appears [61 1].

Press the M key 2 times to return the display back to the [ih 0.0].

Step 6 - How to change the symmetrical current value Pr 62.

NOTE

The new symmetrical current value is calculated by the following method.

Take the value of the maximum current value observed from step 4 and divide it by the motor rated current value (Pr 06 or the name plate value) and then multiply it by 100. e.g. XXX = 0.94 / 1.14 x 100 = 83

This means we would like the drive to fault at 83 percent of the motor rated current. We may want to add a few percent to this to avoid some nuisance trips so we will round this up to 100.

Never exceed a value of 165 for the symmetrical current or raise the value of Pr 06 above the name plate value for the applied voltage.

Press the M button on the key pad. Now, press the \/ button several until the left parameter value changes to Pr 62. If you happen to go passed Pr 62, then use the /\ key to return to Pr 62. Once you are at the flashing Pr 62, press the M key and the parameter value on the right 0.0 should start to flash. Press the /\ key several times until the value of XXX appears [62 XXX.0]. (For our revised calculated example we would have entered 100 [62 100.0].) Press the M key 2 times to return the display back to the [ih 0.0]. The drive has now been configured to trip during a current overload. You can take the drive out of the inhibit state by closing connections B2 and B4.

How to manually recover from an overload.

See the Safety Warning on the first page before starting this step.

You must put the control into inhibit mode by opening B2 and B4.

You must recover from the overload condition by returning the indexer to a dwell position at a reduced speed. You can reduce the motor speed by either changing Pr 18 or turning the speed pot down if you have one wired.

Press the button on the key pad with the red circle.

Put the control out of inhibit mode by closing B2 and B4. If the index drive does not start, then send a start signal. Once you are in a dwell position reset the motor preset value back to its original value or return the speed pot back to its normal setting.

1.25 Drive parameter list for a motor reversing application

You should have a copy of the data sheet for the indexer application in order to set Pr 18 correctly. You must change Pr 10 (Security Level) to 2 or L3 before you can change Pr 18, the preset speed. On the data sheet you will find the motor speed for your application and the motor's rated rpm. Use the following calculation to determine Pr 18. Pr 18 = Pr 39 x Motor Speed for Application / Motor Rated RPM Pr 18 = 60 hz x 1650 rpm / 1750 rpm = 57 hz (round all values up to a whole number)

2 Safety Information

WARNING

CAUTION

NOTE

2.1 Warnings, Cautions and Notes

A Warning contains information, which is essential for avoiding a safety hazard.

A Caution contains information, which is necessary for avoiding a risk of damage to the product or other equipment.

A Note contains information, which helps to ensure correct operation of the product.

2.2 Electrical Safety - general warning

The voltages used in the drive can cause severe electrical shock and/or burns, and could be lethal. Extreme care is necessary at all times when working with or adjacent to the drive.

Specific warnings are given at the relevant places in this guide.

2.3 System design and safety of personnel

The drive is intended as a component for professional incorporation into complete equipment or system. If installed incorrectly, the drive may present a safety hazard.

The drive uses high voltages and currents, carries a high level of stored electrical energy, and is used to control equipment which can cause injury.

System design, installation, commissioning and maintenance must be carried out by personnel who have the necessary training and experience. They must read this safety information and this guide carefully.

The STOP and START controls or electrical inputs of the drive must not be relied upon to ensure safety of personnel. They do not isolate dangerous voltages from the output of the drive or from any external option unit. The supply must be disconnected by an approved electrical isolation device before gaining access to the electrical connections.

The drive is not intended to be used for safety-related functions.

Careful consideration must be given to the function of the drive which might result in a hazard, either through its intended behaviour or through incorrect operation due to a fault. In any application where a malfunction of the drive or its control system could lead to or allow damage, loss or injury, a risk analysis must be carried out, and where necessary, further measures taken to reduce the risk - for example, an over-speed protection device in case of failure of the speed control, or a fail-safe mechanical brake in case of loss of motor braking.

2.4 Environmental Limit s

Instructions within the supplied data and information within the IM-pAC Technical Data Guide regarding transport, storage, installation and the use of the drive must be

complied with, including the specified environmental limits. Drives must not be subjected to excessive physical force.

2.5 Access

Access must be restricted to authorized personnel only. Safety regulations which apply at the place of use must be complied with.

The IP (Ingress Protection) rating of the drive is installation dependant.

Instructions

2.6 Compliance and regulations

The installer is responsible for complying with all relevant regulations, such as national wiring regulations, accident prevention regulations and electromagnetic compatibility (EMC) regulations. Particular attention must be given to the cross-sectional areas of conductors, the selection of fuses and other protection, and protective ground (earth) connections.

The IM-pAC Technical Data Guide contains instructions for achieving compliance with

specific EMC standards.

Within the European Union, all machinery in which this product is used must comply with the following directives:

98/37/EC: Safety of machinery

89/336/EEC: Electromagnetic compatibility

2.7 Motor

Ensure the motor is installed in accordance with the manufacturer's recommendations. Ensure the motor shaft is not exposed.

Standard squirrel cage induction motors are designed for single speed operation. If it is intended to use the capability of a drive to run a motor at speeds above its designed maximum, it is strongly recommended that the manufacturer is consulted first.

Low speeds may cause the motor to overheat because the cooling fan becomes less effective. The motor should be installed with a protection thermistor. If necessary, an electric force vent fan should be used.

The values of the motor parameters set in the drive affect the protection of the motor. The default values in the drive should not be relied upon.

It is essential that the correct value is entered into parameter 06, motor rated current. This affects the thermal protection of the motor.

2.8 Adjusting parameters

Some parameters have a profound effect on the operation of the drive. They must not be altered without careful consideration of the impact on the controlled system. Measures must be taken to prevent unwanted changes due to error or tampering.

2.9 Electrical installation

2.9.1 Electric shock risk

The voltages present in the following locations can cause severe electric shock and may be lethal:

• AC supply cables and connections

• DC bus, dynamic brake cables and connections

• Output cables and connections

• Many internal parts of the drive, and external option units

Unless otherwise indicated, control terminals are single insulated and must not be touched.

Page 34

2.9.2 Isolation device

The AC supply must be disconnected from the drive using an approved isolation device before any cover is removed from the drive or before any servicing work is performed.

2.9.3 STOP function

The STOP function does not remove dangerous voltages from the drive, the motor or any external option units.

2.9.4 Stored charge

The drive contains capacitors that remain charged to a potentially lethal voltage after the AC supply has been disconnected. If the drive has been energized, the AC supply must be isolated at least ten minutes before work may continue.

Normally, the capacitors are discharged by an internal resistor. Under certain, unusual fault conditions, it is possible that the capacitors may fail to discharge, or be prevented from being discharged by a voltage applied to the output terminals. If the drive has failed in a manner that causes the display to go blank immediately, it is possible the capacitors will not be discharged. In this case, consult IMC or their authorized distributor.

2.9.5 Equipment supplied by plug and socket

Special attention must be given if the drive is installed in equipment which is connected to the AC supply by a plug and socket. The AC supply terminals of the drive are connected to the internal capacitors through rectifier diodes which are not intended to give safety isolation. If the plug terminals can be touched when the plug is disconnected from the socket, a means of automatically isolating the plug from the drive must be used (e.g. a latching relay).

2.9.6 Ground leakage current

The drive is supplied with an internal EMC filter capacitor installed. If the input voltage to the drive is supplied through an ELCB or RCD, these may trip due to the ground

leakage current. See section 5.3.1 Internal EMC filter on page 41 for further information

and how to disconnect the internal EMC capacitor.

WARNING

NOTE

The AC supply to the drive must be installed with suitable protection against overload and short circuits. Failure to observe this requirement will cause risk of fire.

The drive must be grounded by a conductor sufficient to carry the prospective fault

current in the event of a fault. See also the warning in section 5.2 Ground leakage

relating to ground leakage current.

To avoid a fire hazard and maintain validity of the UL listing, adhere to the specified tightening torques for the power and ground terminals. Refer to the table below.

Frame size Maximum power terminal screw torque

A 0.5 N m / 4.4 lb in

B and C 1.4 N m / 12.1 lb in

Braking resistor: High temperatures and overload protection

Braking resistors can reach high temperatures. Locate braking resistors so that damage cannot result. Use cable having insulation capable of withstanding the high temperatures.

It is essential that the braking resistor be protected against overload caused by a failure of the brake control. Unless the resistor has in-built protection, a circuit like those shown

Figure 5-1

and

Figure 5-2

should be used, where the thermal protection device disconnects the AC supply to the drive. Do not use AC relay contacts directly in series with the braking resistor circuit, because it carries DC.

When connecting single phase to a dual rated 200V unit, use terminals L1 and L3. For control terminal connections, see Pr 05 on page 51.

For information on the internal EMC filter, see section 5.3.1 Internal EMC filter .

5.2 Ground leakage

The ground leakage current depends upon the internal EMC filter being installed. The drive is supplied with the filter installed. Instructions for removal of the internal EMC filter

are given in section 5.3.2 Removing the internal EMC filter .

WARNING

filter connected and do not take into account any leakage currents of the motor or motor cable.

With internal EMC filter removed

<1mA

In both cases, there is an internal voltage surge suppression device connected to ground. Under normal circumstances, this carries negligible current.

When the internal EMC filter is installed, the leakage current is high. In this case, a permanent fixed ground connection must be provided using two independent conductors each with a cross-section equal to or exceeding that of the supply conductors. The drive is provided with two ground terminals to facilitate this. The purpose is to prevent a safety hazard occurring if a connection is lost. Both ground connections are required to meet the required european standard.

5.2.1 Use of earth (ground ) leakage circuit breakers (ELCB) / residual current device (RCD)

There are three common types of ELCB/RCD:

Type AC - detects AC fault currents Type A - detects AC and pulsating DC fault currents (provided the DC current

reaches zero at least once every half cycle)

Type B - detects AC, pulsating DC and smooth DC fault currents

• Type AC should never be used with drives

• Type A can only be used with single phase drives

• Type B must be used with three phase drives

5.3 EMC

5.3.1 Internal EMC filter

It is recommended that the internal EMC filter is kept in place unless there is a specific reason for removing it.

If the drive is to be used on an IT supply, then the filter must be removed.

The internal EMC filter reduces radio-frequency emissions into the mains supply. Where the motor cable is short, it permits the requirements of EN61800-3 to be met for the second environment.

For longer motor cables, the filter continues to provide a useful reduction in emission level, and when used with any length of shielded cable up to the limit for the drive, it is unlikely that nearby industrial equipment will be disturbed. It is recommended that the filter be used in all applications unless the ground leakage current is unacceptable or the above conditions are true.

Further EMC precautions are required if more stringent EMC emission requirements apply:

• Operation in the first environment of EN 61800-3

• Conformity to the generic emission standards

• Equipment which is sensitive to electrical interference operating nearby

In this case it is necessary to use:

• The optional external EMC filter

• A shielded motor cable, with screen clamped to the grounded metal panel

• A shielded control cable, with screen clamped to the grounded metal panel

Full instructions are given in the IM-pAC Technical Data Guide.

A full range of external EMC filters is also available for use with IM-pAC.

5.4 Control terminals I/O specification

The control circuits are isolated from the power circuits in the drive by basic insulation (single insulation) only. The installer must ensure that the external control circuits are insulated from human contact by at least one layer of insulation (supplementary insulation) rated for use at the AC supply voltage.

42 IM-pAC Getting Started Guide

If the control circuits are to be connected to other circuits classified as Safety Extra Low Voltage (SELV) (e.g. to personal computer), an additional isolating barrier must be included in order to maintain the SELV classification.

Keypad and Display

When in Status mode, pressing and holding the MODE key for 2 seconds will change the display from displaying a speed indication to displaying load indication and vice versa.

Pressing and releasing the MODE key will change the display from status mode to parameter view mode. In parameter view mode, the left hand display flashes the parameter number and the right hand display shows the value of that parameter.

Pressing and releasing the MODE key again will change the display from parameter view mode to parameter edit mode. In parameter edit mode, the right hand display flashes the value in the parameter being shown in the left hand display.

Pressing the MODE key in parameter edit mode will return the drive to the

parameter view mode. If the MODE key is pressed again then the drive will return to

status mode, but if either of the up or down keys are pressed to change the

parameter being viewed before the MODE key is pressed, pressing the MODE key will change the display to the parameter edit mode again. This allows the user to very easily change between parameter view and edit modes while commissioning the drive.

6.4 Saving parameters

Parameters are automatically saved when the MODE key is pressed when going from parameter edit mode to parameter view mode.

6.5 Parameter access

There are 3 levels of parameter access controlled by Pr 10. This determines which parameters are accessible. See Table 6-1.

The setting of the user security Pr 25 determines whether the parameter access is read only (RO) or read write (RW).

Table 6-1

Parameter access (Pr 10) Parameters accessible

L1 Pr 01 to Pr 10 L2 Pr 01 to Pr 60 L3 Pr 01 to Pr 95

6.6 Security codes

Setting a security code allows view only access to all parameters. A security code is locked into the drive when Pr 25 is set to any other value than 0 and

then LoC is selected in Pr 10. On pressing the MODE key, Pr 10 is automatically changed from LoC to L1 and Pr 25 will be automatically set to 0 so as not to reveal the security code.

Pr 10 may be changed to L2 or L3 to allow view only access to parameters.

The drive is enabled and ready for a start command. The output bridge is inactive.

The drive is inhibited because there is no enable command, or a coast to stop is in progress or the drive is inhibited during a trip reset.

The drive has tripped. The trip code will be displayed in the right hand display.

Ur S: Stator resistance is measured each time the drive is enabled and run Ur: No measurement is taken Fd: Fixed boost Ur A: Stator resistance is measured the first time the drive is enabled and run

: Stator resistance measured at each power-up when the drive is enabled and run

Ur I SrE: Square law characteristic

In all Ur modes, the drive operates in open loop vector mode.

The drive default setting is Ur I mode which means that the drive will carry out an autotune every time the drive is powered-up and enabled. If the load is not going to be stationary when the drive is powered-up and enabled, then one of the other modes should be selected. Not selecting another mode could result in poor motor performance or OI.AC, It.AC or OV trips.

As source

Pr 61 to Pr 70 and Pr 71 to Pr 80 can be used to access and adjust advanced parameters.

Example: It is desired that Pr 1.29 (Skip frequency 1) is to be adjusted. Set one of the parameters Pr 71 to Pr 80 to 1.29, the value of Pr 1.29 will appear in the corresponding parameter from Pr 61 to Pr 70. I.e. if Pr 71 is set to 1.29, Pr 61 will contain the value of Pr 1.29 where it can be adjusted.

Some parameters are only implemented if the drive is disabled, stopped or tripped and the STOP/RESET key is pressed for 1s.
