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.
1.2 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.
1.3 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 / start up 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. 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 behavior 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.
1.4 Environmental limits
Instructions within the supplied data regarding transport, storage, installation and the
use of the drive must be complied with, including the specified environmental limits.

1.5 Access
WARNING
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.
information
Safety
1.6 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. If necessary, an electric force vent fan should be used.
1.7 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.
1.8 Electrical installation
1.8.1 Electric shock risk
The voltages present in the following locations can cause severe electric shock and may
be lethal:
• AC supply cables and connections
• Output cables and connections
• Many internal parts of the drive
Unless otherwise indicated, control terminals are single insulated and must not be
touched.
1.8.2 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.
1.8.3 STOP function
The STOP function does not remove dangerous voltages from the drive or the motor.
1.8.4 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 4.3.1 Internal EMC filter on page 14 for further information
and how to disconnect the internal EMC capacitor.
The VFD66 series variable speed drives are intended to control equipment under normal
operating conditions. Where failure or malfunction of a VFD66 drive could lead to an
abnormal operating condition that could cause personal injury or damage to the
equipment or other property, other devices, (limit or safety controls) or systems (alarm or
supervisory) intended to warn of, or protect against, failure or malfunction of the VFD66
drive must be incorporated into and maintained as part of the control system.

WARNING
WARNING
NOTE
NOTE
WARNING
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 4.2 Ground leakage
relating to ground leakage current.
Safety information Rating data
Model Maximum power terminal screw torque
VFD66 0.5 Nm / 4.4 lb in
4.2 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 4.3.2 Removing the internal EMC filter .
With internal EMC filter installed
3 Phase 200V drives
7.8mA AC maximum at 220V, 50Hz (proportional to supply voltage and frequency).
3 Phase 200V drives
10.4mA AC maximum at 400V, 50Hz (proportional to supply voltage and frequency).
The above leakage currents are the leakage currents of the drive with the Internal EMC
filter connected. No account is taken for leakage currents of the motor or motor cable.
With internal EMC filter removed <1mA
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.
4.2.1 Use of ground fault circuit interrupter (GFCI)
There are three common types of GFCI:
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

4.3.3 Emissions Compliance
An internal factory installed EMC filter is provided with all ratings, it is recommended
that it is kept in place unless there is a specific reason for removing it. This internal filter
reduces radio-frequency emissions into the line power supply. When the motor cable is
short, it permits the requirements of EN61800-3:2004 to be met for the second
environment with restricted distribution. For longer motor cables, the filter continues to
provide a useful reduction in emission level. When used with any length shielded motor
cable (up to the limit for the drive), it is unlikely that nearby industrial equipment will be
disturbed.
Installation of an additional external EMC filter as shown in Table 4-1, provides higher
levels of emissions compliance. If the application requires these levels of compliance
then the external filter must be installed in order to ensure compliance with EMC
regulations such as the EC EMC Directive, and to ensure the validity of the CE mark.

* The M5 nuts are provided to connect the shield to ground (earth).
• Physically separate the input and output cables.
• All input and output cables should be fully shielded, with the shield securely
grounded. The motor cable shield should be connected to the ground connection.
• Do not run input cables alongside output cables. Do not bundle input and output
cables together.
• The input ground wire should be connected to the ground connection.
• Ideally, the motor cable shield should be clamped directly to the back plate.
• The EMC filter body needs to be fixed to the same grounded metal part (e.g. the
back plate) as the motor cable shield.

(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.
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.

The VFD66 controls work with most 0 to 5Vdc or 0 to 10Vdc electronic pressure
transducers. For best results, use 0 to 5Vdc, ratiometric P499 Electronic Pressure
Transducers. Ratiometric transducers vary the signal voltage from 10 to 90% of the 5Vdc
supply power as the pressure goes from minimum to maximum of the transducer rating.
Applications using a 0 to 10 Vdc transducer must be powered separately.

No de-rating for 400/460 Vac drives up to 60°C (140°F). Contact JCI application

This is the de-rating with the switching frequency at 3kHz.
De-Rating examples
For these examples, the drive used is a VFD66EBA type. See Figure 5-1 and Table 5-1.
• If the VFD66EBA drive is used in Denver, Colorado (altitude 5200 ft), the output
rating is reduced (see Table 5-1). When the temperature is less than 122°F (50°C),
the VFD66EBA drive is rated for 9.96 amperes, as shown by the equation:
De-Rated maximum output amperes = 10.6 A x 0.94 = 9.96 amperes
• If the VFD66EBA drive is used in Denver, Colorado (altitude 5200 ft) and the
ambient temperature reaches 140°F (60°C), then the VFD66EBA drive is de-rated
to maximum current of 9.0 amperes due to the high ambient temperature and is
further de-rated to 8.46 amperes because of the high altitude.
De-Rated maximum output amperes = 9.0 amperes x 0.94 = 8.46 amperes.

This procedure is written from the first power up of the drive and assumes no terminals
have been connected, no parameters have been changed and no security has been set.
Figure 6-2
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 (or
output current) 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 display flashes between the
parameter number and 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 display shows the
value in the parameter.
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 during commissioning /

Manual input mode
Manual mode uses the keypad buttons to start and stop the motor, as well as increasing
and decreasing the motor speed. It also allows the user to set a constant motor speed.
This mode will be useful, during installation and repair.
The Set point is the keypad reference and is used as an input, with the speed being
adjustable between 0 to 100%. Transducer input will not have any effect on the speed of
the motor.
Figure 7-1 Manual input mode Pr 05 = PAd

The VFD66 controls work with any electronic pressure transducer that generated a 0-5

NOTE
NOTE
WARNING
NOTE
Selected transducer type P399BAA-1C. Pressure range: 0-500psi
P1: Set point range =250psi
P2: Proportional bands = 50psi
Then the fan motor starting point ( min speed) =Set point (P1) - Proportional band (P2) =
250-50=200psi
Fan motor max speed at P1=Set point=250psi
Thus as soon as the pressure transducer input reaches 200psi, the motor starts at
minimum speed, and after reaching 250 psi, the motor reaches Max speed.
Therefore if the Set point (Pr 61) was set to 50% and the Proportional Band (Pr 62) was
set to 10%. This would mean that the drive would run at 60Hz when the input is 2.5V
and at 0Hz when the input is 2V (using the 0 to 5V input range).
Minimum motor speed and motor action as minimum speed cannot be set in this mode.
The VFD66 has line start with a single auto restart after 25s.
The drive can be stopped by pressing the stop/reset button. However, before the drive
can be restarted in either Std or EPt mode, the mode will need to be changed.

No Function Range Defaults Type
Voltage mode select Ur S, Ur, Fd, Ur A, Ur I, SrE Ur A RW
41
Ur S: Stator resistance is measured each time the drive is enabled and run
Ur: No measurement is taken
Fd: Fixed boost (V/Hz)
Ur A: Stator resistance is measured the first time the drive is enabled and run
Ur I: Stator resistance measured at each power up when the drive is enabled and run
SrE: Square law characteristic
In all Ur modes, the drive operates in open loop vector mode.
The drive default setting is Ur A mode, which means that the drive will carry out an
autotune the first 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 the first time, 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.
Once the autotune has been performed successfully in Ur A mode, Fixed boost mode
will then be used.
The Fixed boost mode should be used for multiple motor applications.
If the autotune fails i.e. trips on rS, due to no motor being connected, the voltage mode
will then be Ur mode.
