1 Safety Information
1.1 Warnings, Cautions and Notes
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 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.
1.4 Environmental Limits
Instructions within the supplied data and information within Chapter 10 Technical
specifications on page 49 regarding transport, storage, installation and the use of the
drive must be complied with, including the specified environmental limits.
A Warning contains information, which is essential for avoiding a safety hazard.
WARNING
A Caution contains information, which is necessary for avoiding a risk of damage to the
product or other equipment.
CAUT IO N
A Note contains information, which helps to ensure correct operation of the product.
NOTE

6VFD67 Size A to D Getting Started Guide
www.johnsoncontrols.com Issue Number: 1
1.5 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.
1.6 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.
Within the European Union, all machinery in which this product is used must comply
with the following directives:
98/37/EC: Safety of machinery
2004/108/EC: Electromagnetic compatibility
1.7 Motor
Ensure the motor is installed in accordance with the manufacturer's recommendations.
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 or a protection
thermistor can be installed.
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.
1.8 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.
1.9 Electrical installation
1.9.1 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.
1.9.2 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.

Information
1.9.3 STOP function
The STOP function does not remove dangerous voltages from the drive, the motor or
any external option units.
1.9.4 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 Johnson Controls Inc or their authorized
distributor.
1.9.5 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).
1.9.6 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, GFCI or RCD, these may trip due to the ground
leakage current. See section 4.3.1 Internal EMC filter on page 15 for further information
and how to disconnect the internal EMC capacitor.
The VFD67 series variable speed drives are intended to control equipment under normal
operating conditions. Where failure or malfunction of a VFD67 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 VFD67
drive must be incorporated into and maintained as part of the control system.
WARNING
Risk of thermal damage
The VFD67 control can generate and dissipate significant heat. Mount the control on a
metal, concrete, or ciderblock mounting surface. Mounting the VFD67 control on
surfaces made of wood or other heat-sensitive material may result in damage to the
mounting surface.
CAUT ION
Risk of equipment damage
Motors used with the VFD67 controls must meet certain specifications for proper
performance and operation. Motors that do not meet these specifications may be
damaged.
CAUT ION
Risk of electrical shock
The printed wiring board and its components are at AC line voltage. Direct or indirect
contact with line voltage can result in personal injury or death.
WARNING

8VFD67 Size A to D Getting Started Guide
www.johnsoncontrols.com Issue Number: 1
Risk of electrical shock
The VFD67 drive remains electrically charged for a period of time after the power is
removed. To avoid possible electrical shock, wait at least 10 minutes after AC supply
power has been disconnected from the VFD67 drive before servicing the control. Failure
to wait until the VFD67 drive fully discharges could cause electrical shock, personal
injury, or death.
WARNING
Risk of equipment damage
Connect each of these items to the VFD67 drive using a separate conduit for each set
of wires:
• Line voltage supply power
• Line voltage output power to motor
• Low voltage signals from input devices
Running different voltage and frequency wires in the same conduit can create electronic
noise or harmonics, which may damage the condenser fan motors.

NOTE
Fuses/MCB
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.
WARNING
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.
WARNING
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.
WARNING
Frame size Maximum power terminal screw torque
A 0.5 N m / 4.4 lb in
B, C and D 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
in
Figure 4-1 and Figure 4-2 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.
WARNING
When connecting single phase to a dual rated 200V unit, use terminals L1 and L3.
NOTE
For control terminal connections, see Pr 05 on page 24.

4.2.1 Use of earth (ground) leakage circuit breakers (ELCB) / ground fault
circuit interrupter (GFCI) / 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
4.3 EMC
4.3.1 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.
When the internal EMC filter is used on the VFD67 size D, the motor cables (U, V and
The above leakage currents are just the leakage currents of the drive with the internal EMC
filter connected and do not take into account any leakage currents of the motor or motor cable.
NOTE
In both cases, there is an internal voltage surge suppression device connected to
ground. Under normal circumstances, this carries negligible current.
NOTE
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.

W) need to be fed twice through a ferrite ring (provided with the drive), so that the drive
meets the requirements of operating in the second environment.
4.3.2 Removing the internal EMC filter
Figure 4-3 Removal and re-fitting of internal EMC filter
4.3.3 Further EMC precautions
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 shield clamped to the grounded metal panel
• A shielded control cable, with shield clamped to the grounded metal panel
A full range of external EMC filters is also available for use with VFD67.

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.
WARNING
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.
WARNING
See Pr 05 on page 24 (Drive configuration) for terminal connection / set-up diagrams and
details.

If the enable terminal is opened, the drive’s output is disabled and the motor will coast to
a stop. The drive will not re-enable for 1.0s after the enable terminal is closed again.
Following a drive trip, opening and closing the enable terminal will reset the drive. If the
run forward or run reverse terminal is closed, the drive will run straight away.
Following a drive trip and a reset via the stop/reset key, the enable, run forward or run
reverse terminals will need to be opened and closed to allow the drive to run. This
ensures that the drive does not run when the stop/reset key is pressed.
The enable, run forward and run reverse terminals are level triggered apart from after a
trip where they become edge triggered.
If the enable and run forward or enable and run reverse terminals are closed when the
drive is powered up, the drive will run straight away up to a set speed.
If both the run forward and run reverse terminals are closed, the drive will stop under the
control of the ramp and stopping modes set in Pr 30 and Pr 31.

5.3 Selecting and changing parameters
Figure 5-2
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 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.
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.
