Guidelines for Enclosure Mounting (IP20 Units)
• IP20 drives are suitable for use in pollution degree 1 environments, according to IEC-664-1. For pollution
degree 2 or higher environments, drives should be mounted in a suitable control cabinet with sufcient
ingress protection to maintain a pollution degree 1 environment around the drive.
• Enclosures should be made from a thermally conductive material.
• Ensure the minimum air gap clearances around the drive as shown below are observed when mounting
the drive.
• Where ventilated enclosures are used, there should be venting above the drive and below the drive to
ensure good air circulation. Air should be drawn in below the drive and expelled above the drive.
•
In any environments where the conditions require it, the enclosure must be designed to protect the
PACMotion VFD against ingress of airborne dust, corrosive gases or liquids, conductive contaminants (such
as condensation, carbon dust, and metallic particles) and sprays or splashing water from all directions.
• High moisture, salt or chemical content environments should use a suitably sealed (non-vented) enclosure.
The enclosure design and layout should ensure that the adequate ventilation paths and clearances are left to
allow air to circulate through the drive heatsink. Emerson recommend the following minimum sizes for drives
mounted in non-ventilated metallic enclosures:
Dimension Z assumes that the drives are mounted side-by-side with no clearance.
Typical drive heat losses are <3% of operating load conditions.
Above are guidelines only and the operating ambient temperature of the drive MUST be maintained at all times.

Protective Earth (PE) Connection
Grounding Guidelines
Adequate safety earthing must be provided in accordance with local wiring rules and codes of practice.
The ground terminal of each PACMotion VFD should be connected back to the common safety earth bar
to maintain touch potentials within safe limits. The ground terminal of each PACMotion VFD should be
individually connected DIRECTLY to the site ground bus bar (through the EMC lter if installed). PACMotion
VFD ground connections should not loop from one drive to another, or to, or from any other equipment.
Ground impedance must conform to local industrial safety regulations and/or electrical codes.
To meet UL regulations, UL approved ring crimp terminals should be used for all ground wiring connections.
The integrity of all ground connections should be checked periodically.
Protective Earth Conductor
The Cross sectional area of the PE Conductor must be at least equal to that of the incoming supply
conductors.
Motor Ground
The driven motor must be locally connected to a suitable ground location to maintain touch potentials within
safe limits. In addition, the motor ground must be connected to one of the ground terminals on the drive.
Ground Fault Monitoring
As with all inverters, a leakage current to earth can exist. The PACMotion VFD is designed to produce the
minimum possible leakage current whilst complying with worldwide standards. The level of current is
affected by motor cable length and type, the effective switching frequency, the earth connections used and
the type of RFI lter installed. If an ELCB (Earth Leakage Circuit Breaker) is to be used, the following conditions
apply:
• A Type B Device must be used.
• Individual device should be used for each PACMotion VFD.
• The device must be suitable for protecting equipment with a DC component in the leakage current.
• The device should be not sensitive to high frequency leakage current.
Shield Termination (Cable Screen)
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
terminating or EMI clamp to connect the shield to the safety ground terminal, refer to page 34.
GFK-3111A PACMotion VFD AC Variable Speed Drive User Guide 25
Incoming Power Connection
NOTE For IP20 Frame Size 8 it is important that the input supply phase orientation is correct, i.e. L1>L1,
L2>L2, L3>L3, failure to do so will result in a “Ph-Seq” trip.
WARNING
Ensure there is at least 30 seconds between each power-on.
Suitability
All PACMotion VFD models are designed for use on a single phase or balanced three phase supply depending
on the model.
For all models and ratings when working with an IT Supply network, or any power supply type where the
phase to earth voltage may exceed the phase to phase voltage (such as ungrounded supplies), the internal
EMC lter and surge protection must be disconnected before connecting the supply. Refer to section Internal
EMC Filter and Varistors – Disconnection Procedure on page 89 for further information.
For three phase supply models, a maximum of 3% imbalance is allowed between phases.
Cable Selection
• For 1 phase ac supply, power should be connected to L1/L, L2/N.
• For a DC Supply, the main power cables should be connected to L1/L, L2/N.
• For 3 phase ac supplies, the mains power cables should be connected to L1, L2, and L3. Phase sequence is
not important. Neutral connection is not required.
For compliance with CE and C Tick EMC requirements, refer to section refer to page 34.
• A xed installation is required according to IEC61800-5-1 with a suitable disconnecting device installed
between the PACMotion VFD and the main Power Source. The disconnecting device must conform to the
local safety code / regulations (e.g. within Europe, EN60204-1, Safety of machinery).
• The cables should be dimensioned according to any local codes or regulations. Maximum dimensions for
each drive model are given in section Input/Output Power and Current Ratings on page 84.
Fuse / Circuit Breaker Selection
• Suitable fuses to provide wiring protection of the input power cable should be installed in the incoming
supply line, according to the data in section Input/Output Power and Current Ratings on page 84.
• The fuses must comply with any local codes or regulations in place. In general, type gG (IEC 60269) or
UL type J fuses are suitable (exception: Eaton Bussmann FWP series must be used for size 6A & 6B IP20
models); however in some cases type aR fuses may be required. The operating time of the fuses must be
below 0.5 seconds.
• Where allowed by local regulations, suitably dimensioned type B MCB circuit breakers of equivalent rating
may be utilised in place of fuses, providing that the clearing capacity is sufcient for the installation.
• The maximum permissible short circuit current at the PACMotion VFD Power terminals as dened in
IEC60439-1 is 100 kA.
• The PACMotion VFD provides thermal and short circuit protection for the connected motor and motor
cable.
26 PACMotion VFD AC Variable Speed Drive User Guide GFK-3111A
Input Choke
An optional Input Choke is recommended to be installed in the supply line for drives where any of the
following conditions occur:
• The incoming supply impedance is low or the fault level / short circuit current is high.
NOTE For IP20 Frame Size 8 the input current level will vary according to supply impedance. At minimum a
1% line choke must be installed. Installing a 4% line choke further helps towards minimising harmonic current
distortion and total current levels. 1% and 4% line chokes are available.
• The supply is prone to dips or brown outs.
• An unbalanced supply system is used (3 phase drives) where the voltage levels during on load operation
exceed the designed 3% capacity of the PACMotion VFD.
• The power supply to the drive is via a busbar and brush gear system (typically overhead Cranes).
In all other installations, an input choke is recommended to ensure protection of the drive against power
supply faults.
Operation of 3 Phase drives from a Single Phase Supply
A special function of PACMotion VFD allows all drives designed for operation on 3 phase supplies to be
operated on a single phase supply of the correct rated voltage at up to 50% of the nominal capacity.
For Example, Model Number ODP-2-64450-3KA4N can be operated on a single phase supply, 380 – 480 volts,
with the maximum output current limited to 45 Amps.
The supply must be connected to the L1 and L2 terminals of the drive.
Operation with DC Power Supply or Common DC Bus
PACMotion VFD models provide terminals to directly connect to the DC Bus for applications which require
this. For further information on using the DC Bus connections, please refer to your Emerson sales Partner.
Motor Connection
• The drive inherently produces fast switching of the output voltage (PWM) to the motor compared with
operation of the motor directly from the mains supply. Most modern industrial motors are wound for
operation with a variable speed drive and will have insulation rated accordingly. However, on some
motors the quality of insulation may be insufcient or unknown. In such cases the motor manufacturer
should be consulted and preventative measures may be required prior to operating with the drive.
• The motor should be connected to the PACMotion VFD U, V, and W terminals using a suitable 3 or 4 core
cable. Where a 3 core cable is utilised, with the shield operating as an earth conductor, the shield must
have a cross sectional area at least equal to the phase conductors when they are made from the same
material. Where a 4 core cable is utilised, the earth conductor must be of at least equal cross sectional
area and manufactured from the same material as the phase conductors.
• Automatic switchgear should not be installed between the drive output and the motor, opening and
closing contacts in this circuit whilst the drive is energised will inevitably reduce the lifetime of the drive
and could cause product failure. If an isolator is required to be placed between the drive and the motor in
order to comply with local regulations, the device must not be operated when the drive is running.
• For compliance with the European EMC directive, a suitable screened (shielded) cable should be used.
Braided or twisted type screened cable where the screen covers at least 85% of the cable surface area,
designed with low impedance to HF signals are recommended as a minimum. Installation within a
suitable steel or copper tube is generally also acceptable.
The motor earth must be connected to one of the PACMotion VFD earth terminals to provide a low
impedance path for common mode leakage current to return to the drive. This is best achieved in practice by
using a cable with suitable shielding which provides a low impedance path at high frequencies, and ensuring
correct, low impedance earth bonding of the motor cable at both ends. For further information, refer to
page 34.

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. This operational voltage is normally selected when installing the motor by selecting
either STAR or DELTA connection. STAR always gives the higher of the two voltage ratings.
PACMotion VFD units feature an internal brake transistor, tted as standard for all models. The brake resistor
should be connected to the DC+ and BR terminals of the drive. These terminals are shrouded, and the
shrouding should be removed to access the terminals.

Software protection against brake resistor overload is carried out within the drive. For correct protection of
the brake resistor, the following settings are required:
• Set P1-14 = 201 (where 201 is the default password setting for advanced parameter access).
• Enter the resistance of the brake resistor in P6-19 (Ohms).
• Enter the power of the brake resistor in P6-20 (kW).

It is highly recommended to equip the drive with a main contactor
in order to provide an additional thermal overload protection for the
braking resistor.
The contactor should be wired so that it will open when the resistor
overheats, otherwise the drive will not be able to interrupt the main
supply if the brake chopper remains closed (short-circuited) in a fault
situation.
It is also recommended to wire the thermal overload protection to a

+24 V DC Input / Output
When the mains power is applied to the drive, terminal 1 provides a +24 V DC output, maximum load
100 mA. This may be used to activate digital inputs or provide power to sensors.
When no mains power is applied to the drive, the drive control electronics may be powered from an external
+24 V DC source. When powered in this way, all analog and digital I/O and communication functions remain
operative, however the motor may not be operated, which allows safe testing and commissioning of the
installation without risk of high voltage being present. When powered in this way, the drive requires up
to 100 mA.
Digital Inputs
Up to ve digital inputs are available. The function of the inputs is dened by parameters P1-12 and P1-13,
which are explained in section Control Terminal Functions on page 48.
Analog Inputs
Two analog inputs are available, which may also be used as digital Inputs if required. The signal formats are
selected by parameters as follows:
• Analog Input 1 Format Selection Parameter P2-30.
• Analog Input 2 Format Selection Parameter P2-33.
These parameters are described more fully in section Parameter Group 2 - Extended Parameters on page 56.
The function of the analog input, e.g. for speed reference or PID feedback for example is dened by
parameters P1-12 and P1-13. The function of these parameters and available options are described in section
Control Terminal Functions on page 48.

Safe Torque Off
Safe Torque Off will be referred to as “STO” through the remainder of this section.
Responsibilities
The overall system designer is responsible for dening the requirements of the overall “Safety Control
System” within which the drive will be incorporated; furthermore the system designer is responsible for
ensuring that the complete system is risk assessed and that the “Safety control System” requirements have
been entirely met and that the function is fully veried, this must include conrmation testing of the “STO”
function before drive commissioning.
The system designer shall determine the possible risks and hazards within the system by carrying out a
thorough risk and hazard analysis, the outcome of the analysis should provide an estimate of the possible
hazards, furthermore determine the risk levels and identify any needs for risk reduction. The “STO” function
should be evaluated to ensure it can sufciently meet the risk level required.
What STO Provides
The purpose of the “STO” function is to provide a method of preventing the drive from creating torque in
the motor in the absence of the “STO” input signals (Terminal 12 with respect to Terminal 13), this allows
the drive to be incorporated into a complete safety control system where “STO” requirements need to be
fullled.
1
The “STO” function can typically eliminate the need for electro-mechanical contactors with cross-checking
auxiliary contacts as per normally required to provide safety functions.
2
The drive has the “STO” function built-in as standard and complies with the denition of “Safe torque off” as
dened by IEC 61800-5-2:2007.
The “STO” function also corresponds to an uncontrolled stop in accordance with category 0 (Emergency
Off), of IEC 60204-1. This means that the motor will coast to a stop when the “STO” function is activated, this
method of stopping should be conrmed as being acceptable to the system the motor is driving.
The “STO” function is recognised as a fail-safe method even in the case where the “STO” signal is absent
and a single fault within the drive has occurred, the drive has been proven in respect of this by meeting the
following safety standards:

What STO Does Not Provide
WARNING
Disconnect and ISOLATE the drive before attempting any work on it. The “STO” function does not prevent
high voltages from being present at the drive power terminals.
WARNING
1
NOTE The “STO” function does not prevent the drive from an unexpected re-start. As soon as the “STO”
inputs receive the relevant signal it is possible (subject to parameter settings) to restart automatically. Based
on this, the function should not be used for carrying out short-term non-electrical machinery operations
(such as cleaning or maintenance work).
WARNING
2
NOTE In some applications additional measures may be required to full the systems safety function needs:
the “STO” function does not provide motor braking. In the case where motor braking is required a time delay
safety relay and/or a mechanical brake arrangement or similar method should be adopted, consideration
should be made over the required safety function when braking as the drive braking circuit alone cannot be
relied upon as a fail-safe method.
WARNING
When using permanent magnet motors and in the unlikely event of multiple output power devices failing then the
motor could effectively rotate the motor shaft by 180/p degrees (Where p denotes number of motor pole pairs).
“STO” Operation
When the “STO” inputs are energised, the “STO” function is in a standby state, if the drive is then given a
“Start signal/command” (as per the start source method selected in P1-13) then the drive will start and
operate normally.
When the “STO” inputs are de-energised then the STO Function is activated and stops the drive (Motor will
coast), the drive is now in “Safe Torque Off” mode.
To get the drive out of “Safe Torque Off” mode then any “Fault messages” need to be reset and the drive
“STO” input needs to be re-energised.
“STO” Status and Monitoring
There are a number of methods for monitoring the status of the “STO” input, these are detailed below:
Drive Display
In Normal drive operation (Mains AC power applied), when the drives “STO” input is de-energised (“STO”
Function activated) the drive will highlight this by displaying “InHibit”.
NOTE If the drive is in a tripped condition then the relevant trip will be displayed and not “InHibit”.
Drive Output Relay
• Drive relay 1: Setting P2-15 to a value of “13” will result in relay opening when the “STO” function is activated.
• Drive relay 2: Setting P2-18 to a value of “13” will result in relay opening when the “STO” function is activated.

WARNING
The “STO” wiring shall be protected from inadvertent short circuits or tampering which could lead to failure
of the “STO” input signal, further guidance is given in the diagrams below. In addition to the wiring guidelines
for the “STO” circuit below, section Figure 26: Recommended Installation for EMC Compliance on page 34
should also be followed. The drive should be wired as illustrated below; the 24 V DC signal source applied to
the “STO” input can be either from the 24 V DC on the drive or from an External 24 V DC power supply.

Enabling the “STO” Function
The “STO” function is always enabled in the drive regardless of operating mode or parameter changes made
by the user.
Testing the “STO” Function
Before commissioning the system the “STO” function should always be tested for correct operation, this
should include the following tests:
• With the motor at standstill, and a stop command given to the drive (as per the start source method
selected in P1-13):
o De-energise the “STO” inputs (Drive will display “INHIBIT”).
o Give a start command (as per the start source method selected in P1-13) and check that the drive still
displays “Inhibit” and that the operation is in line with the section “STO” Operation and section “STO”
Status and Monitoring.
• With the motor running normally (from the drive):
o De-energise the “STO” inputs.
o Check that the drive displays “INHIBIT” and that the motor stops and that the operation is in line with
the section and section “STO” Operation and section “STO” Status and Monitoring.
“STO” Function Maintenance
The “STO” function should be included within the control systems scheduled maintenance program so that
the function is regularly tested for integrity (Minimum once per Year), furthermore the function should be
integrity tested following any safety system modications or maintenance work. If drive fault messages are
observed refer to section Fault Messages on page 90 for further guidance.

Resetting the Drive Following a Trip
PACMotion VFD has many protection features, designed to protect both the drive and motor from accidental
damage. When any of these protection features are activated, the drive will trip, and display a fault message.
The fault messages are listed in section Fault Messages on page 90.
When a trip occurs, after the cause of the trip has been investigated and rectied, the user can reset the trip
in one of the following ways:
• Press the keypad Stop key.
• Power off the drive completely, then power on again.
• If P1-13 > 0, switch off digital input 1, then back on again.
• If P1-12 = 4, reset via the eldbus interface.
• If P1-12 = 6, reset via CAN.

Parameters
Parameter Set Overview
The PACMotion VFD Parameter set consists of 10 groups as follows:
• Group 0 – Read Only Monitoring Parameters
• Group 1 – Basic Conguration Parameters
• Group 2 – Extended Parameters
• Group 3 – PID Control Parameters
• Group 4 – High Performance Motor Control Parameters
• Group 5 – Field Bus Parameters
• Group 6 – Advanced Options
• Group 7 – Advanced Motor Control
• Group 8 – Application Parameters
• Group 9 – Advanced I/O Selection
When the PACMotion VFD is reset to factory defaults, or is in its factory supplied state, only Group 1
Parameters can be accessed. In order to allow access to parameters from the higher level groups, the access
code must be changed as follows.
P1-14 = P2-40 (Default setting = 101). With this setting, parameter groups 1 – 5 can be accessed, along with
the rst 50 parameters in Group 0.
P1-14 = P6-30 (Default setting = 201). With this setting, all parameters are accessible.
Parameter Group 1 – Basic Parameters
The basic parameter group allows the user to:
• Enter the motor nameplate information
o P1-07 = Motor Rated Voltage
o P1-08 = Motor Rated Current
o P1-09 = Motor Rated Frequency
o P1-10 = (Optionally) Motor Rated Speed
• Dene the operating speed limits
o P1-01 = Maximum Frequency or Speed
o P1-02 = Minimum Frequency or Speed
• Dene the acceleration and deceleration times used when starting and stopping the motor, or changing
speed
o P1-03 = Acceleration Time
o P1-04 = Deceleration Time
• Select where the drive should receive it’s command signals from, and determine what functions are
associated with the drive control terminal inputs
o P1-12 Selects the control source
o P1-13 Assigns the functions to the digital inputs
These parameters will often provide enough functions to allow the user to complete basic commissioning in
simple applications. The parameters are described in more detail below.

the rate controlled by P1-04 as described above. In this mode, the drive
brake transistor (where tted) is disabled.
When the enable signal is removed, the drive output is immediately
disabled, and the motor will coast (freewheel) to stop. If the load can
continue to rotate due to inertia, and the drive may possibly be reenabled whilst the motor is still rotating, the spin start function (P2-26)
should be enabled. In this mode, the drive brake transistor (where tted)
is disabled.
When the enable signal is removed, the drive will ramp to stop, with the
rate controlled by P1-04 as described above. The PACMotion VFD Brake
chopper is also enabled in this mode.
When the enable signal is removed, the drive output is immediately
disabled, and the motor will coast (freewheel) to stop. If the load can
continue to rotate due to inertia, and the drive may possibly be reenabled whilst the motor is still rotating, the spin start function (P2-26)
should be enabled. The drive brake chopper is enabled in this mode;
however, it will only activate when required during a change in the drive
frequency setpoint, and will not activate when stopping.
As Option 0, but additionally, AC Flux braking is used to increase the
available braking torque.
When enabled, the Energy Optimiser attempts to reduce the overall
energy consumed by the drive and motor when operating at constant
speeds and light loads. The output voltage applied to the motor is
reduced. The Energy Optimiser is intended for applications where the
drive may operate for some periods of time with constant speed and
light motor load, whether constant or variable torque.

P1-10Motor rated speed0300000RPM
This parameter can optionally be set to the rated (nameplate) rpm of the motor. When set to the default
value of zero, all speed related parameters are displayed in Hz, and the slip compensation for the motor
is disabled. Entering the value from the motor nameplate enables the slip compensation function, and
the PACMotion VFD display will now show motor speed in estimated rpm. All speed related parameters,
such as Minimum and Maximum Speed, Preset Speeds etc. will also be displayed in Rpm.
Note When the drive is operated with the optional Encoder Feedback Interface, this parameter must be
set to the correct nameplate Rpm of the connected motor.
P1-11Boost voltage0.0Drive Rating Dependent%
Voltage boost is used to increase the applied motor voltage at low output frequencies, in order to
improve low speed and starting torque. Excessive voltage boost levels may result in increased motor
current and temperature, and force ventilation of the motor may be required.
An automatic setting (Auto) is also possible, whereby the PACMotion VFD will automatically adjust this
parameter based on the motor parameters measured during an autotune.

Control Terminal Functions
For standard applications and operation, the basic control of the drive and functions of all drive input
terminals can be congured using just two parameters, P1-12 and P1-13. P1-12 is used to dene the source
of all control commands and the primary speed reference source. P1-13 then allows fast selection of Analog
and Digital Input functions based on a selection table.

Overview
PACMotion VFD uses a Macro approach to simplify the conguration of the Analog and Digital Inputs. There
are two key parameters which determine the input functions and drive behaviour:
• P1-12 – Selects the main drive control source and determines how the output frequency of the drive is
primarily controlled.
• P1-13 – Assigns the Macro function to the analog and digital inputs.
Additional parameters can then be used to further adapt the settings, e.g.
• P2-30 – Used to select the format of the analog signal to be connected to analog input 1, e.g. 0 – 10 Volt,
4 – 20 mA.
• P2-33 – Used to select the format of the analog signal to be connected to analog input 2, e.g. 0 – 10 Volt,
4 – 20 mA.
• P2-36 – Determines whether the drive should automatically start following a power on if the Enable Input
is present.
• P2-37 – When Keypad Mode is selected, determines at what output frequency / speed the drive should
start, following the enable command, and also whether the keypad start key must be pressed or if the
Enable input alone should start the drive.
The following diagrams and tables provide an overview of the functions of each terminal macro function, and
a simplied connection diagram for each.

The Skip Frequency function is used to avoid the PACMotion VFD operating at a certain output frequency, for
example at a frequency which causes mechanical resonance in a particular machine. Parameter P2-09 denes
the centre point of the skip frequency band, and is used conjunction with P2-10. The PACMotion VFD output
frequency will ramp through the dened band at the rates set in P1-03 and P1-04 respectively, and will not
hold any output frequency within the dened band. If the frequency reference applied to the drive is within
the band, the PACMotion VFD output frequency will remain at the upper or lower limit of the band.

Parameter Group 3 – PID Control
Overview
PACMotion VFD provides an internal PID controller. Parameters for conguration of the PID controller are
located together in Group 3. For simple applications, the user needs to only dene the setpoint source (P3-05
to select the source or P3-06 for a xed setpoint), feedback source (P3-10) and adjust the P Gain (P3-01),
I time (P3-02) and optionally the differential time (P3-03).
The PID operation is uni-directional, and all signals are treated as 0 – 100% to provide a simple, intuitive
operating format.

P3-11PID error limit to enable ramps0.025.00.0%
Denes a threshold PID error level, whereby if the difference between the setpoint and feedback values
is less than the set threshold, the internal ramp times of the drive are disabled. Where a greater PID error
exists, the ramp times are enabled to limit the rate of change of motor speed on large PID errors, and react
quickly to small errors.
Setting to 0.0 means that the drive ramps are always enabled. This parameter is intended to allow the user
to disable the drive internal ramps where a fast reaction to the PID control is required, however by only
disabling the ramps when a small PID error exists, the risk of possible over current or over voltage trips
being generated are reduced.
Applies a scaling factor to the displayed PID feedback, allowing the user to display the actual signal level
from a transducer, e.g. 0 – 10 Bar etc.
P3-13PID wakeup error level0.0100.05.0%
Sets a programmable level whereby if the drive enters standby motor whilst operating under PID

regardless of whether the drive is enabled or disabled. This can result
in the output of the PID controller reaching the maximum level prior to

drive is enabled
In this operating mode, the PID controller only operates when the drive
is enabled, and hence will always start from zero when the drive is
enabled.

Parameter Group 4 – High Performance Motor Control
Overview
Parameters relating to the motor control are located together in Group 4. These parameters allow the user to:
• Select the motor type to match the connected motor.
• Carry out an autotune.
• Dene the torque limits and setpoint source for control methods that support this (vector control
methods only).
PACMotion VFD can operate with both Asynchronous Induction Motors, the type most commonly seen
today, and also some synchronous motors. The sections below provide basic guidance on how to adjust the
parameters to operate with the required motor type.
Asynchronous IM Motors
IM Motor Control Methods
IM Motors may be operated in the following modes:
• V/F Speed Control (Default Mode)
o This mode provides the simplest control, and is suitable for a wide range of applications.
• Sensorless Vector Torque Control
o This method is suitable for specic applications only, which require the motor torque to be the
primary control function, rather than speed, and should be used with extreme care only in specic
applications.
• Sensorless Vector Speed Control
o
Operating in Sensorless Vector Speed Control Mode
PACMotion VFD can be programmed by the user to operate in Sensorless Vector mode, which provides
enhanced low speed torque, optimum motor speed regulation regardless of load and accurate control of
the motor torque. In most applications, the default Voltage Vector control mode will provide adequate
performance, however if Sensorless Vector operation is required, use the following procedure.
• Ensure advanced parameter access is enabled by setting P1-14 = 101.
• Enter the motor nameplate details into the relevant parameters as follows:
o P1-07 Motor Rated Voltage
o P1-08 Motor Rated Current
o P1-09 Motor Rated Frequency
o (Optional) P1-10 Motor Rated Speed (Rpm)
o P4-05 Motor Power Factor.
• Select Sensorless Vector Speed Control mode by setting P4-01 = 0.
• Ensure that the motor is correctly connected to the drive.
• Carry out a motor data Autotune by setting P4-02 = 1.
This method provides increased starting torque compared to V/F mode, along with improved motor speed
regulation with changing load conditions. This method is suitable for more demanding applications.
WARNING
The Autotune will begin immediately when P4-02 is set regardless of the status of the drive enable signal.
Whilst the autotune procedure does not drive or spin the motor, the motor shaft may still turn slightly. It is
not normally necessary to uncouple the load from the motor; however the user should ensure that no risk
arises from the possible movement of the motor shaft.
WARNING
It is essential that the correct motor data is entered into the relevant drive parameters. Incorrect parameter
settings can result in poor or even dangerous performance.

Synchronous Motors
Overview
PACMotion VFD provides open loop vector control of the following synchronous motor types.
Permanent Magnet AC (PM AC) Motors and Brushless DC (BLDC) Motors
PACMotion VFD can be used to control Permanent Magnet AC or Brushless DC motors without a feedback
encoder or resolver. These motors operate synchronously, and a vector control strategy is used to maintain
correct operation. In general, the motor can be operated between 10% - 100% of rated speed with a correctly
selected and congured drive. Optimum control is achieved when the motor back EMF / Rated speed ratio is
>= 1 V/Hz. Motors with Back EMF / Rated frequency ratio below this level may not operate correctly, or may
operate only with reduced speed range.
PM AC and BLDC motor control employs the same strategy, and the same commissioning method is applied.
WARNING
Permanent Magnet motors (including BLDC) produce an output voltage known as the Back EMF when the
shaft is rotated. The user must ensure that the motor shaft cannot rotate at a speed where this Back EMF
exceeds the voltage limit for the drive, otherwise damage can occur.
The following parameter settings are necessary before attempting to operate the motor.
• Ensure advanced parameter access is enabled by setting P1-14 = 101 (default value for security access).
• Enter the motor nameplate details into the relevant parameters as follows:
o P1-07 Back EMF at Rated Frequency / Speed (kE)
This is the voltage imposed by the magnets at the drive output terminals when the motor operates at
rated frequency or speed. Some motors may provide a value for volts per thousand RPM, and it may
be necessary to calculate the correct value for P1-07.
o P1-08 Motor Rated Current
o P1-09 Motor Rated Frequency
o (Optional) P1-10 Motor Rated Speed (Rpm).
• Select PM Motor Speed control mode by setting P4-01 = 3 or BLDC Motor Speed Control by setting P4-01 = 5.
• Ensure that the motor is correctly connected to the drive.
• Carry out a motor data Autotune by setting P4-02 = 1.
o The autotune measures the electrical data required from the motor to ensure good control.
• To improve motor starting and low speed operation, the following parameters may require adjustment:
o P7-14: Low Frequency Torque Boost Current: Injects additional current into the motor to help rotor
alignment at low output frequency. Set as % of P1-08.
o P7-15: Low Frequency Torque Boost Frequency Limit: Denes the frequency range where the torque
boost is applied. Set as % of P1-09.
Following the steps above, it should be possible to operate the motor. Further parameter settings are possible
to enhance the performance if required, please refer to your Emerson Sales Partner for more information.

When set to 1, the drive immediately carries out a non-rotating autotune to measure the motor parameters
for optimum control and efciency. Following completion of the autotune, the parameter automatically
returns to 0.
P4-03Speed control P-gain0.1400.050.0%
Sets the proportional gain value for the speed controller when operating in Vector Speed or Vector Torque
motor control modes (P4-01 = 0 or 1). Higher values provide better output frequency regulation and
response. Too high a value can cause instability or even over current trips. For applications requiring best
possible performance, the value should be adjusted to suit the connected load by gradually increasing the
value and monitoring the actual output speed of the load until the required dynamic behaviour is achieved
with little or no overshoot where the output speed exceeds the setpoint.
In general, higher friction loads can tolerate higher values of proportional gain, and high inertia, low friction
loads may require the gain to be reduced.
P4-04Speed control I time0.0102.0000.050s
Sets the integral time for the speed controller. Smaller values provide a faster response in reaction to motor
load changes, at the risk of introducing instability. For best dynamic performance, the value should be
adjusted to suit the connected load.

Serial Communications
RS-485 Communications
PACMotion VFD has an RJ45 connector located within the wiring enclosure of the drive. This connector
allows the user to set up a drive network via a wired connection. The connector contains two independent
RS485 connections, one for Emerson’s communication Protocol and one for Modbus RTU / CANBus. Both
connections can be used simultaneously. The communication connection is always available, and can be used
simultaneously with other interfaces, however only one other interface may be used, e.g. If Modbus RTU is in
use, CAN is disabled. If a Fieldbus Option Module (E.g. PROFINET) is inserted into the drive, both Modbus and
CAN are disabled. The electrical signal arrangement of the RJ45 connector is shown as follows:
• Ensure the network taps for the drive
are kept as short as possible
•Terminate the network cable shield at
the controller only. Do not terminate
the drive!
at
0 Volt common must be connected
•
across all devices and to reference
0 Volt terminal at the controller
• Do not connect the 0V Common
of the network to power ground
Modbus RTU and CANbus connection should be made via the RJ45 connector. The pin assignments are as
shown above, in section RS-485 Communications.
• Modbus RTU and CANbus networks require three conductors for best operation and to eliminate
common mode voltages on the drive terminals:
o RS485+
o RS485-
o 0 Volt Common
• Connection should be made using a suitable dual twisted pair, shielded cable, with a wave impedance of
120 Ohms.
• Use one of the twisted pairs to connect to the RS485+ and RS485- of each drive.
• Use one conductor of the remaining pair to connect together all the 0 volt common connection
terminals.
• The cable shield should be connected to a suitable clean ground point to prevent interference with the
screen maintained as close as possible to the cable terminations.
• Do not connect the 0 Volt Common, RS485- or RS485+ to ground at any point.
• Network terminating resistor (120 Ohms) should be used at the end of the network to reduce noise.

Modbus RTU Communications
Modbus Telegram Structure
The PACMotion VFD supports Master / Slave Modbus RTU communications, using the 03 Read Multiple
Holding Registers and 06 Write Single Holding Register commands and 16 Write Multiple Holding Registers
(Supported for registers 1 – 4 only). Many Master devices treat the rst Register address as Register 0;
therefore it may be necessary to convert the Register Numbers detailed in section Modbus Control &
Monitoring Registers by subtracting 1 to obtain the correct Register address.
Modbus Control & Monitoring Registers
The following is a list of accessible Modbus Registers available in the PACMotion VFD.
• When Modbus RTU is congured as the Fieldbus option, all of the listed registers can be accessed.
• Registers 1 and 2 can be used to control the drive provided that Modbus RTU is selected as the primary
command source (P1-12 = 4) and no Fieldbus Option Module is installed in the drive Option Slot.
• Register 4 can be used to control the acceleration and deceleration rate of the drive providing that
Fieldbus Ramp Control is enabled (P5-07 = 1).
• Registers 6 to 24 can be read regardless of the setting of P1-12.

Modbus Parameter Access
All User Adjustable parameters (Groups 1 to 5) are accessible by Modbus, except those that would directly
affect the Modbus communications, e.g.
• P5-01 Drive Fieldbus Address – see also P5-16 Drive Modbus Address.
• P5-03 Modbus RTU Baud Rate.
• P5-04 Modbus RTU Data Format.
All parameter values can be read from the drive and written to, depending on the operating mode of the
drive – some parameters cannot be changed whilst the drive is enabled for example.
When accessing a drive parameter via Modbus, the Register number for the parameter is the same as the
parameter number, e.g. Parameter P1-01 = Modbus Register 101.
Modbus RTU supports sixteen bit integer values, hence where a decimal point is used in the drive parameter,
the register value will be multiplied by a factor of ten, e.g. Read Value of P1-01 = 500, therefore this is 50.0 Hz.
For further details on communicating with PACMotion VFDs using Modbus RTU, please refer to your local
Emerson Sales Partner.

CAN Open Communication
Overview
The CANopen communication prole in the PACMotion VFD is implemented according to the specication
DS301 version 4.02 of CAN in automation (www.can-cia.de). Specic device proles such as DS402 are not
supported.
Basic Operation Setup
The CANopen communication function is enabled by default after power up however in order to use any
control functions through CANopen, Parameter P1-12 must be set to 6.
The CAN communication baud rate can is selected by parameter P5-02. Available baud rates are 125 kbps,
250 kbps, 500 kbps, 1 Mbps. Default settings is 500 kbps.
The Node ID is set up through drive address parameter P5-01 with a default value of 1.
COB ID and Functions
PACMotion VFD provides the following default COB-ID and functions:
Process data object.
PDO1 is pre-mapped and enabled by default.
PDO2 is pre-mapped and disabled by default.
Transmission mode, COB-ID and mapping can be congured.
SDO channel can be used for drive parameter access.
COB-ID can be congured to other value.
NOTE
1. The PACMotion VFD SDO channel only supports expedited transmission.
2. The PACMotion VFD can only support up to 2 Process Data Objects (PDO). All PDOs are pre-mapped,
however PDO2 is disabled by default. Table 2 gives the default PDO mapping information.
3. Customer conguration (mapping) will NOT be saved during power down. This means that the CANopen
conguration will restore to its default condition each time the drive is powered up.

Input/Output Power and Current Ratings
The following tables provide the output current rating information for the various PACMotion VFD models.
Emerson always recommend that selection of the correct PACMotion VFD is based upon the motor full load
current at the incoming supply voltage.
Please note that the maximum cable length stated in the following tables indicate the maximum permissible
cable length for the drive hardware and does not take into consideration EMC compliance.
• Ratings shown above apply to 40°C Ambient temperature. For derating information, refer to section Table
62: Derating for Ambient Temperature
• The drive is protected against short-circuit from power output to protective earth for all rated cable
lengths, cable sizes and cable types.
• 3 phase drive can be connected to single phase supply when the output current is 50% derated.
• The maximum cable lengths stated here are based on hardware limitations and do NOT take into
consideration any requirements for compliance to any EMC standards. Please see section for further
information.
• The maximum motor cable length stated applies to using a shielded motor cable. When using an
unshielded cable, the maximum cable length limit may be increased by 50%. When using the Emerson
recommended output choke, the maximum cable length may be increased by 100%.
• The PWM output switching from any inverter when used with a long motor cable length can cause an
increase in the voltage at the motor terminals, depending on the motor cable length and inductance. The
rise time and peak voltage can affect the service life of the motor. Emerson recommend using an output
choke for motor cable lengths of 50m or more to ensure good motor service life.
• For IP20 Frame Size 8 the Vector Speed and Torque control modes may not operate correctly with
long motor cables and output lters. It is recommended to operate in V/F mode only for cable lengths
exceeding 50m.
• Supply and motor cable sizes should be dimensioned according to local codes or regulations in the
country or area of installation.
• For UL compliant installation, use use only with copper stranded conductors rated 75degC, UL Class CC or
Class J Fuses (exception: Eaton Bussmann FWP series must be used for size 6A & 6B IP20 models).

Input Power Supply Requirements
Table 60: Input Power Supply Requirements
Supply Voltage200 – 240 RMS Volts for 230 Volt rated units, + /- 10% variation allowed.
380 – 480 Volts for 400 Volt rated units, + / - 10% variation allowed.
500 – 600 Volts for 600 Volt rated units, + / - 10% variation allowed.
ImbalanceMaximum 3% voltage variation between phase – phase voltages allowed.
All PACMotion VFD units have phase imbalance monitoring. A phase imbalance of > 3% will
result in the drive tripping. For input supplies which have supply imbalance greater than
3% (typically the Indian sub- continent & parts of Asia Pacic including China) Emerson
recommends the installation of input line reactors. Alternatively, the drives can be operated as
a single phase supply drive with 50% derating.

Derating Information
Derating of the drive maximum continuous output current capacity is required when:
• Operating at ambient temperature in excess of 40°C / 104°F for enclosed drives (Non UL Approved).
• Operating at Altitude in excess of 1000m/ 3281 ft.
• Operation with Effective Switching Frequency higher than 8 kHz for IP20 models and 4 kHz for
IP55/IP66 models.
The following derating factors should be applied when operating drives outside of these conditions.

Example of applying Derating Factors
A 4 kW, IP66 drive is to be used at an altitude of 2000 metres above sea level, with 12 kHz switching
frequency and 45°C ambient temperature.
From the table above, we can see that the rated current of the drive is 9.5 Amps at 40°C,
Firstly, apply the switching frequency derating, 12 kHz, 25% derating
9.5 Amps x 75% = 7.1 Amps
Now, apply the derating for higher ambient temperature, 2.5% per °C above 40°C = 5 x 2.5% = 12.5%
7.1 Amps x 87.5% = 6.2 Amps
Now apply the derating for altitude above 1000 metres, 1% per 100m above 1000m = 10 x 1% = 10%
7.9 Amps x 90% = 5.5 Amps continuous current available.
If the required motor current exceeds this level, it will be necessary to either:
• Reduce the switching frequency selected.
• Use a higher power rated drive and repeat the calculation to ensure sufcient output current is available.
