Throughout this manual, important safety information is included, with warning and
caution notes. Please read the following information carefully, and all warning and
caution information in the manual.

Indicates a potentially hazardous
situation which, if not avoided, could
result in injury or death.

Indicates a potentially hazardous
situation which, if not avoided, could
result in damage to property.

Safety of machinery, and safety-critical applications

The level of integrity offered by the SE2 control functions, for example, Stop/Start,
Forward/Reverse, and Maximum Speed, is not sufficient for use in safety-critical
applications without independent channels of protection. All applications where
malfunction could cause injury or loss of life must be subject to a risk assessment
and further protection provided where needed. Within the European Union, all
machinery in which this product is used must comply with Directive 89/392/EEC,
Safety of Machinery. In particular, the electrical equipment should comply with
EN60204-1.

• SE2 units should be installed only by qualified electrical personnel and in accordance with
local and national regulations and codes of practice.

• Electric shock hazard! Disconnect and ISOLATE the SE2 before attempting any work on it.
High voltages are present at the terminals and within the drive for up to 10 minutes after
the electrical supply has been disconnected.

• Where supply to the drive is through a plug and socket connector, do not disconnect until
10 minutes have elapsed after turning off the power supply.

• Ensure correct earthing (grounding) connections. The earth (ground) cable must be
sufficient to carry the maximum supply fault current which normally is limited by the fuses
or MCB.

• The STOP function does not remove potentially lethal high voltages. Be sure to ISOLATE
the drive and wait 10 minutes before starting any work on it.

• If it is desired to operate the drive at any frequency/speed above the rated speed (P-503/
P-511) of the motor, consult the manufacturers of the motor and the driven machine about
suitability for over-speed operation.

• The fan (if fitted) inside the SE2 starts automatically when the heat sink temperature
reaches approximately 45 degrees C.

1.3 Electromagnetic compatibility (EMC)

The SE2 is designed to high standards of EMC and is optionally fitted with an internal
EMC filter. This EMC filter is designed to reduce the conducted emissions back into
the supply via the power cables for compliance with European standards.

It is the responsibility of the installer to ensure that the equipment or system into
which the product is installed complies with the EMC legislation of the country of
use. Within the European Union, equipment into which this product is incorporated
must comply with 89/336/EEC, EMC.

For use on domestic supplies, shielded motor cable must be used with the shield
terminated to earth ground on both the motor and drive sides. The installation must
be carried out by qualified installation engineers, observing good wiring practice
such as power and signal cable segregation and correct shielding techniques to
minimize emissions. When installed in this way, an SE2 unit with a built-in filter has
emission levels lower than those defined in EN61800-3, category C2 for first
environments for shielded cable lengths of up to 5 meters.

For cable lengths longer than 5 meters, the emission levels may exceed those
defined by EN61800-3, category C2. In this case, further mitigation methods, such as
fitting an external filter) must be employed if the emission limits are to maintained.

When used on industrial supplies, or second environments, the installation must be
carried out by qualified installation engineers, observing good wiring practice such
as power and signal cable segregation and correct shielding techniques to minimize
emissions. The emissions limits defined by EN61800-3, category C3 (second
environments) are maintained for shielded cable lengths of up to 25 meters. The
cable shield should be connected to earth ground on both the drive and motor sides.

4. Power wiring

This chapter provides information about connecting power wiring to the SE2 drive.

HAZARDOUS VOLTAGE

• Read and understand this manual in its entirety before installing or
operating the SE2 drive. Installation, adjustment, repair, and
maintenance of these drives must be performed by qualified
personnel.

• Disconnect all power before servicing the drive. WAIT 5 MINUTES
until the DC bus capacitors discharge.

DANGER

• DO NOT short across DC bus capacitors or touch unshielded
components or terminal strip screw connections with voltage
present.

• Install all covers before applying power or starting and stopping the
drive.

• The user is responsible for conforming to all applicable code
requirements with respect to grounding all equipment.

• Use the dedicated ground terminal to ground the drive unit. Do not
use mounting screws, bolts, or the chassis.

• Many parts in this drive, including printed circuit boards, operate at
line voltage. DO NOT TOUCH. Use only electrically-insulated tools.

Before servicing the drive:

• Disconnect all power.

• Place a “DO NOT TURN ON” label on the drive disconnect.

• Lock the disconnect in the open position.

Failure to observe these precautions will cause shock or burn,
resulting in severe personal injury or death.

4.1 General wiring information

Be sure that the installation wiring conforms with local standards. Where local
codes exceed these requirements, they must be followed.

4.1.1 Wiring Practices

When making power and control connections, observe these precautions:

• Never connect input AC power to the output terminals T1/U, T2/V, or T3/W.
Damage to the drive will result.

• Power wiring to the motor must have the maximum possible separation from
all other power wiring. Do not run in the same conduit; this separation reduces
the possibility of coupling electrical noise between circuits.

• Cross conduits at right angles whenever power and control wiring intersect.

Email: [e-mail] • Fax [phone]

14  vacon Power wiring

• Good wiring practice also requires separation of control circuit wiring from all
power wiring. Since power delivered from the drive contains high frequencies
which may cause interference with other equipment, do not run control wires in
the same conduit or raceway with power or motor wiring.

4.1.2 Considerations for Power Wiring

Power wiring refers to the line and load connections made to terminals L1/R, L2/S,
L3/T, and T1/U, T2/V, T3/W respectively. Select power wiring as follows:

• Use only VDE, UL or CUL recognized wire.

• Wire voltage rating must be a minimum of 300 V for 230 Vac systems and 600 V
(Class 1 wire) for 400 Vac systems.

• Wire gauge must be selected based on 125% of the continuous input current
rating of the drive. Wire gauge must be selected from wire tables for 75 °C
insulation rating, and must be of copper construction. See “Ratings” on

page 40 for the continuous output ratings for the drive.

See the following table for a summary of power terminal wiring specifications.

Specifications

NOTE: Wire type not specified by the manufacturer. Some types of wire may not fit within the
constraints of the conduit entry and bend radius inside the drive.

4.1.3 Grounding Guidelines

The ground terminal for each SE2 unit should be individually connected directly to
the site ground bus bar (through the filter, if installed). SE2 ground connections
should not loop from one drive to another, or to/from any other equipment. Ground
loop impedance must conform to local industrial safety regulations. To meet UL
regulations, UL approved ring crimp terminals should be used for all ground wiring
connections.

If a system ground fault monitor is to be used, only Type B devices should be used
to avoid nuisance tripping.

The safety ground is required by code for the drive. One of these points must be
connected to adjacent building steel (girder, joist), a floor ground rod, or bus bar.

Grounding points must comply with national and local industrial safety regulations
and/or electrical codes.

The drive safety ground must be connected to the system ground. Ground impedance
must conform to the requirements of national and local industrial safety regulations
and/or electrical codes. The integrity of all ground connections should be checked
periodically.

For shield termination, the safety ground terminal provides a grounding point for
the motor cable shield. The motor cable shield connected to this terminal (drive end)
should also be connected to the motor frame (motor end). Use a shield terminator or
EMI clamp to connect the shield to the safety ground terminal. Note: When shielded
cable is used for control and signal wiring, the shield should be grounded at the
source end only, not at the drive end.

The motor ground must be connected to one of the ground terminals on the drive.

4.1.4 Wiring Precautions

Connect the drive according to the connection diagram shown in Figure 4-1 on

page 16, ensuring that motor terminal box connections match the output

specifications of the drive.

For recommended cabling and wire sizing, see “Technical data” on page 40.

4.2 Drive and motor connections

For one-phase supply, power should be connected to L1/L and L2/N.

For three-phase supplies, power should be connected to L1, L2, and L3. Phase
sequence is not important.

The motor should be connected to U, V, and W.

For drives with a dynamic brake transistor, an optional external braking resistor will
need to be connected to +DC and BR when required. The brake resistor circuit should
be protected by a suitable thermal protection circuit.

4.3 Motor terminal box connections

Most general-purpose motors are wound for operation on dual voltage supplies. This
is indicated on the nameplate of the motor.

Ensure that the motor is connected for the proper voltage configuration that
matches the SE2 drive’s output rating.

the direction of rotation if bi­directional keypad mode is
enabled.

This key is used for displaying
real-time information, for
accessing and entering
parameter edit mode, and for
storing parameter changes.

This key is used to increase
speed in real-time mode, or
to increase parameter values
in parameter edit mode.

This key is used to decrease
speed in real-time mode, or
to decrease parameter
values in parameter edit
mode.

Use this key to reset a tripped
dri ve. Wh en in Key pad mode ,
use it to STOP a running
drive.

When in programming mode,
and viewing a parameter, use
this key to access the
parameter so the data can be
changed with the UP or
DOWN arrows.

This key enters the data into
memory.

6.2 Changing parameters

To change a parameter value in Level 1, press and release the PROG key while the
drive displays STOP. The display changes to P-010, indicating parameter 010.

To access all parameters (Level 2), hold down the SHIFT key and press the PROG
key.

To change Level 1 or Level 2 parameters, use the UP or DOWN arrows to select the
desired parameter to view or change. To display the value of the parameter, press
and release the SHIFT key. To change the value, use the UP or DOWN keys. Store the
change by pressing and releasing the ENTER key.

To return to real-time mode, press and release the PROG key. The display shows
STOP if the drive is stopped, or displays the real-time information (for example,
speed) if the drive is running.

6.3 Resetting factory default settings

To reset factory default parameter settings, press the UP, DOWN, and STOP keys for
more than two seconds. The display shows P-dEF. Press the STOP key to
acknowledge and reset the drive.

6.4 Terminal control

When delivered, the SE2 is in the factory default state, meaning that it is set to
operate in terminal control mode and all parameters (P-xxx) have the default values
as indicated in “Parameters” on page 22. To use terminal control:

1. Connect the motor to the drive, checking the motor connection matches that of the
voltage rating.

2. Enter the motor data from the nameplate. P-509 = motor rated voltage, P-510 = motor
rated current, P-503 = motor rated frequency.

3. Connect a control switch between the control terminals 1 and 2, ensuring that the
contact is open (drive disabled)

4. Connect a potentiometer (1kΩ to 10kΩ maximum) between terminals 5 and 7, and the

wiper to terminal 6.

5. With the potentiometer set to zero, switch on the supply to the drive. The display
shows StoP.

6. Close the control switch, terminals 1-2. The drive is now enabled and the output
frequency and speed are controlled by potentiometer. The display shows zero speed
in Hz (H 0.0) with the potentiometer turned to minimum.

7. Turn the potentiometer to maximum. The motor will accelerate to 60 Hz (the default
value of P-302) under the control of the accelerating ramp time P-402. The display
shows 60 Hz (H 60.0) at max speed.

8. To display motor current (A), briefly press the PROG key.

9. Press PROG again to return to the speed display.

10. To stop the motor, either turn the potentiometer back to zero, or disable the drive by
opening the control switch (terminals 1-2). If the enable/disable swtich is opened, the
drive decelerates to stop, at which time the display shows StoP . If the potentiometer
is turned to zero with the enable / disable closed, the display shows 0.0 Hz (H 0.0). If
left in this state for 20 seconds, the drive goes into standby mode, and the display
shows Standby, waiting for a speed reference signal.

6.5 Keypad control

To control the SE2 from the keypad in a forward direction only, set P-201 = 1, and
follow these steps:

1. Connect the motor as for terminal control (described in “Terminal control” on

page 20).

2. Enable the drive by installing a hard-wired jumper between control terminals 1 and 2.
The display shows StoP.

3. Press the RUN key. The display shows H 0.0.

4. Press the UP key to increase speed.

5. The drive runs in a forward direction, increasing speed until you release the UP key.

The rate of acceleration is controlled by the setting of P-402.
Be sure to check this before starting.

6. Press the DOWN key to decrease speed. The drive decreases speed until you release
the DOWN key. The rate of deceleration is controlled by the setting in P-403.

7. Press the STOP key. The drive decelerates to rest at the rate set in P-403.

8. The display shows StoP, at which point the drive is disabled.

To preset a target speed before enabling the drive:

1. Press the RUN key while the drive is stopped. The display shows the target speed.

2. Use the UP and DOWN keys to adjust the speed as needed, then press the STOP key
to return the display to StoP.

3. Press the RUN key to start the drive accelerating to the target speed.

To allow the SE2 to be controlled from the keypad in a forward or reverse direction,
set P-201 = 2, and follow these steps:

Note: Operation is the same as when P-201 = 1, for start, stop, and changing speed.

1. Press the RUN key. The display changes to H 0.0.

2. Press the UP key to increase speed.

3. The drive runs in a forward direction, increasing speed until you release the UP key.

The rate of acceleration is controlled by the setting of P-402.
The maximum speed is the speed set in P-302. Be sure to
check this before starting.

4. To reverse the direction of rotation of the motor, press the RUN key again.

If you scroll to P-00, pressing SHIFT then displays “P-00 A”, where A represents the
secondary number within P-00 (from 1-20). You can then scroll to the required P-00
parameter.

To display the value of that particular group zero parameter, press SHIFT again.

For parameters having multiple values (for example, software ID), pressing the UP
or DOWN keys displays the different values within that parameter.

To return to the next level up, press ENTER. Pressing PROG (without pressing the
UP or DOWN keys) changes the display to the next level up (main parameter level,
that is, P-000). If the UP or DOWN keys are pressed while on the lower level (for
example, P00-05), to change the P-00 index, press PROG to display that parameter
value.

Motor starting: load stalled or jammed. Check
for star-delta motor wiring error.

Motor accelerating/decelerating: the accel/
decel time too short, requiring too much power.
If P-402 or P-403 cannot be increased, a bigger
drive is required.

Cable fault between drive and motor.
Check to see when the decimal points are

flashing (drive in overload) and either decrease
acceleration rate or load. Check cable length to
be sure it is within specifications range.

Over current in the brake resistor circuit. Check
the cabling to the brake resistor. Check brake
resistor value. Ensure that minimum resistance
values from the rating tables are observed.

Brake resistor overload. Increase deceleration
time, reduce load inertia, or add further brake
resistors in parallel. Ensure that minimum
resistance values from the rating tables are
observed.

Check wiring to motor, look for ph-ph or ph­ground short circuit.

Check drive ambient temperature; is additional
space or cooling needed?

Check that drive is not forced into overload.
Supply problem, or increase decel ramp time

with P-403.
This occurs routinely when power is switched off.

If it occurs during run operation, check the
power supply voltage.

Check drive ambient temperature. Additional
space or cooling may be required.

Trip occurs when ambient temperature is less
than 0 degrees C.
