2.2Drive Description
The SP500 drive is an AC PWM (pulse-width-modulated) inverter that operates on
single- or three-phase power. See figures 2.1 and 2.2. AC input power is applied to the
drive’s input terminals. Voltage transients are suppressed by three
metal-oxide-varistor (MOV) suppressors. These suppressors keep any input voltage
transients within the maximum voltage rating of the input diode module.
The input diode module rectifies the incoming AC voltage into a constant DC bus
voltage which is filtered by the DC bus capacitor bank. An internal DC-to-DC power
supply uses power from the DC bus and provides the necessary voltages required by
the drive. Under regulator software control, the IGBT (insulated-gate
bipolar-transistor) inverter bridge converts the constant DC voltage into an AC PWM
waveform. The regulator switches the IGBT inverter bridge using a 4, 6, or 8 kHz
carrier frequency (user-selectable). A low carrier frequency maximizes the power
rating of the drive but also increases acoustic noise. A high carrier frequency selection
reduces acoustic noise but results in a derating of the drive’s efficiency.
The volts per hertz (V/Hz) regulator governs the open-loop operation of the drive for
adjustable-speed performance of AC induction and synchronous motors. The
regulator maintains a ratio of voltage to output frequency that provides constant or
variable torque across a wide speed range. Drive operation can be adjusted by the
parameters entered through the keypad. A microprocessor on the Regulator board
controls drive regulation. See figure 2.3. The Regulator board accepts internal power
feedback signals and an external speed reference signal. The Regulator board
provides display data for a four-character display, which is used to indicate drive
parameters, parameter values, and fault codes.
The drive can be controlled either locally through the keyboard and display (see
section 7) or remotely through the terminal strip (see section 5).
The drive is intended to operate trip-free under any condition. The drive uses selected
signals to extend the acceleration (starting) and deceleration (stopping) rates of the
motor when an overcurrent condition occurs. When a fault does occur, however, the
regulator generates an instantaneous electronic trip (IET) signal to turn the drive off
(coast-to-rest). The drive stores an indication or record of the IET fault, which can be
viewed on the four-character display. After a fault, the STOP/RESET key or a
user-supplied IET RESET pushbutton must be pressed to reset the IET signal and
clear the fault from the drive.

and/or permanent damage to the drive. Remove power correction
capacitors before proceeding.
ATTENTION:The user is responsible for conforming with all applicable
local, national, and international codes.
CHAPTER 3
It is important to properly plan before installing an SP500 drive to ensure that the
drive’s environment and operating conditions are satisfactory . Note that no devices are
to be mounted behind the drive. This area must be kept clear of all control and power
wiring. Read the following recommendations before continuing with the drive
installation.
Before deciding on an installation site, consider the following guidelines:
• The area chosen should allow the space required for proper airflow as specified in
sections 3.1.1 and 3.1.2.
• Do not install the drive above 1000 meters (3300 feet) without derating output
power. For every 91.4 meters (300 feet) above 1000 meters (3300 feet), derate the
output current by 1%.
• Verify that the drive location will meet the following environmental conditions:
Operating temperature (ambient): 0 to +40°C (32 to 104°F)
Storage temperature (ambient): –40 to +65°C (–40 to +149°F)
Humidity: 5 to 95% (non-condensing)
• Verify that NEMA 1 drives can be kept clean, cool, and dry.
• Be sure NEMA 1 drives are located away from oil, coolants, or other airborne
contaminants.
• Verify that the AC power distribution system meets the service conditions specified
in table A.1.

3.2.3 Recommen ded Control and Signal Wire Sizes
Table 3.6 shows the recommended wire sizes to connect I/O signals to the terminal
strip on the Regulator board. The minimum wire insulation rating is 600V. Operator
controls can be up to 303 meters (1000 feet) from the SP500 drive. All signal wires
should be twisted-pair.

3.2.4 Recommended Motor Lead Lengths
The following motor lead lengths are recommended to reduce line disturbances and
noise. See figure 3.5.
• For applications using one motor, motor lead length should not exceed 76 meters
(250 feet).
• For applications with multiple motors, total motor lead length should not exceed 76
meters (250 feet).
When total lead length exceeds 76 meters (250 feet), nuisance trips can occur,
caused by capacitive current flow to ground. Note that these capacitively-coupled
currents should be taken into consideration when working in areas where drives are
running. If the motor lead length must exceed these limits, the addition of output line
reactors or other steps must be taken to correct the problem. See tables 3.7 and 3.8.
Note that the motor lead lengths shown in table 3.7 are maximum distances. Your
application may be restricted to a shorter motor lead length due to:

3.4Installing an Emergency Stop
ATTENTION:The user must provide an external, hardwired emergency
stop circuit outside of the drive circuitry. This circuit must disable the
!
Depending upon the requirements of the application, the SP500 drive can be
programmed to provide either a coast-to-rest (default) or a ramp-to-rest (user-option)
operational stop without physical separation of the power source from the motor. Refer
to sections 5.2 and 8.3 (parameter F-16) for more information on how to program an
operational stop.
In addition to the operational stop, users must provide a hardwired emergency stop
external to the drive. The emergency stop circuit must contain only hardwired
electromechanical components. Operation of the emergency stop must not depend on
electronic logic (hardware or software) or on the communication of commands over an
electronic network or link.
3.4.1 Complying with Machinery Safety Standard EN 60204-1:1992
This section applies to users who must comply with machinery safety standard
EN 60204-1:1992, part 9.2.5.4, Emergency Stop.
The SP500 drive coast-to-rest stop is a category 0 operational stop.The ramp-to-rest
stop is a category 1 operational stop.
system in case of improper operation. Uncontrolled machine operation
may result if this procedure is not followed.
The required external hardwired emergency stop must be either a category 0 or 1
stop, depending on the user’s risk assessment of the associated machinery. In order
to fully comply with machinery safety standard EN 60204-1:1992, part 9.2.5.4, at least
one of the two stop methods must be a category 0 stop. Refer to Appendix D for more
information.
3.5Motor Considerations
To obtain motor nameplate horsepower, the drive’s output current rating at the
selected carrier frequency should be equal to or greater than motor nameplate
current. If the motor nameplate current rating is higher than the drive’s output current
rating, derate motor horsepower by the ratio of the drive’s output ampere rating (at the
selected carrier frequency) to the motor nameplate current. Note that this
approximation is only accurate if the drive and the motor have nearly the same rating.
3.5.1 Single-Motor Applications
Size the drive and motor for the load and speed requirements of the specific
application.
The motor’s operating current must not exceed the drive’s rated output current (at the
selected carrier frequency). In addition, the motor’s horsepower rating (for example, 1,
2, 3, 5, 7, 10, 15, and 20 HP) must not be more than one horsepower range larger
than the drive’s horsepower rating.
SP500 System Planning
3-9
Page 34
If the motor will be operated below one-half of its rated speed, the motor overload
relay may not protect the motor because of reduced cooling action due to the reduced
speed. A motor thermostat, internal to the motor, should be installed to monitor the
actual temperature of the windings.
3.5.2 Multiple- Motor Applications
One drive can run two or more motors. Adhere to the following requirements to assure
correct drive operation in this case:
• When starting and stopping all the motors at the same time (using the drive for
starting and stopping), the sum of the full-load sine wave currents of all the motors
must be equal to or less than the maximum sine wave output current at the selected
carrier frequency for the drive.
For example:I
FLA
+I
FLA
+I
FLA
=I
TLA
(Motor 1)(Motor 2) (Motor 3) (Total Load)
Where: I
<100% rated drive output at the selected carrier frequency
TLA
• When one or more of the motors connected to the output of the drive are to start
independently (using a secondary switching device to add or remove the motor from
the circuit):
Any motor that starts or stops while the drive is running must have a current rating
less than 10% of the maximum sine wave current rating of the drive at the selected
carrier frequency.
The sum of the maximum full-load sine wave currents of all the motors connected
continuously to the drive must be less than the maximum output current rating under
all conditions.
Note that each motor requires separate thermal overload protection (for example, a
motor relay or a motor thermostat).

Attach the drive to the selected flat, vertical surface using the mounting holes
provided. Enclosure A drives have two mounting holes, which are accessible after the
cover is removed. Enclosure B, C, and D drives have four mounting holes. In order to
maintain a flat mounting surface and to ensure that bolt tightness is maintained, use
washers under the bolt heads. Refer to figures 3.1 through 3.4 for drive mounting
dimensions. Use the following user-supplied mounting bolts and washers:
• Enclosure A drives: two M6 (1/4”)
• Enclosure B drives: four M8 (5/16”)
• Enclosure C drives: four M8 (5/16”)
• Enclosure D drives: four M8 or M10 (5/16” or 3/8”)
CHAPTER 4
Installing the Drive
4.2Routing Wires
All wiring should be installed in conformance with the applicable local, national, and
international codes (e.g., NEC/CEC). Signal wiring, control wiring, and power wiring
must be routed in separate conduits to prevent interference with drive operation. Do
not route wires behind the drive. Use grommets when hubs are not provided to guard
against wire chafing. Figures 4.1 through 4.4 show the wire routing, grounding
terminal, and power terminal strips of the SP500 drives.
ATTENTION:Do not route signal and control wiring in the same conduit
with power wiring. This can cause interference with drive operation.
!
Do not route more than three sets of motor leads through a single conduit. This will
minimize cross-talk that could reduce the effectiveness of noise reduction methods. If
more than three drive/motor connections per conduit are required, you must use
shielded cable. If possible, each conduit should contain only one set of motor leads.
ATTENTION:Unused wires in conduit must be grounded at both ends
to avoid a possible shock hazard caused by induced voltages. Also, if a
!
drive sharing a conduit is being serviced or installed, all drives using this
conduit should be disabled to eliminate the possible shock hazard from
cross-coupled motor leads.

4.3Installing External Components
Install the input power and output power components that are located outside of the
SP500 enclosure. See figure 5.1. The following sections describe disconnect,
transformer, and AC line branch protection installation.
4.3.1 Disconnects
An input disconnect (for example, a switch or circuit breaker) must be installed in the
line before the drive input terminals in accordance with local, national, and
international codes (e.g., NEC/CEC). Size the disconnect according to the inrush
current as well as any additional loads the disconnect might supply. Coordinate the
trip rating for the current (10 to 12 times the full load current) with that of the input
isolation transformer, if used. Refer to section 4.3.3 for additional information.
4.3.2 Input AC Line Branch Protection
ATTENTION:Most codes require that upstream branch protection be
provided to protect input power wiring.
!
User-supplied branch circuit protection fuses must be installed according to the
applicable local, national, and international codes (for example, NEC/CEC). The fuses
must be installed in the line before the drive’s AC input terminals. Table 3.9 provides
fuse values.
4.3.3 Transformers
ATTENTION:Distribution capacity above the maximum recommended
system KVA rating (100 KVA for 115/230 VAC, 1000 KVA for
!
Input isolation transformers may be needed to help eliminate the following:
460/575 VA C) requires the use of an isolation transformer, a line reactor,
or other means of adding similar impedance to the drive’s input power
wiring.
ATTENTION:When the AC line is shared directly with other SCRrectified drives, an optional snubber resistor braking kit might be required
to alleviate excess DC bus voltage
• Damaging line voltage transients.
• Line noise from the drive back to the incoming power source.
• Damaging currents that could develop if a point inside the drive becomes grounded.
Observe the following guidelines when installing an isolation transformer:
• A power disconnecting device must be installed between the power line and the
primary of the transformer. If the power disconnecting device is a circuit breaker, the
circuit breaker trip rating must be coordinated with the inrush current (10 to 12 times
the full load current) of the transformer.
4-6
SP500 AC Drive Installation and Operation Manual Version 3.1
Page 41
• Do NOT use an input isolation transformer rated more than 100 KV A for 230 VAC (or
1000 KVA for 460 VAC) with less than 5% impedance directly ahead of the drive
without additional impedance between the drive and the transformer.
If your SP500 application requires the use of an output transformer, contact Reliance
Electric for assistance.
4.3.4 Output Contactors
ATTENTION:Any disconnecting means wired to drive output terminals
U, V, and W must be capable of disabling the drive if opened during drive

Output contactors provide a positive means of disconnecting the motor from the drive.
If your SP500 application requires the use of output contactors, contact Reliance
Electric for assistance.
operation. If opened during drive operation, the drive will continue to
produce output voltage between U, V, W. An auxiliary contact must be
used to simultaneously disable the drive or output component damage
may occur.
4.3.5 Mechanical Motor Overload Protection
To provide the motor with overload protection, local, national, and international codes
(for example, NEC/CEC) require that a motor thermostat, internal to the motor, be
installed or an electronic thermal motor overload relay, sized to protect the motor, be
installed between the motor and the drive’s output termin als.
The Electronic Thermal Overload parameter (F-14) may be used in place of the
electronic thermal motor overload relays in single motor applications. Note, however,
that temperature-sensing devices integral to the motor are the best way of thermallyprotecting AC motors under all conditions. Parameter F-14 must be enabled to provide
overload protection. Refer to section 8.3 for the parameter description.
In multiple motor applications, each motor must have its own user-supplied overload
protection.
4.4Setting the Analog Input Jumper on the Regulator
Board
SP500 drives have an analog speed reference input. This is a jumper-selectable 0 to
10 VDC or 0 to 20 mA input with programmable gain and offset adjustments
(parameters F-11 and F-12). Jumper J6 on the Regulator board is set to match the
type of incoming analog signal, either voltage or current. See figures 2.2, 4.5, and 5.3.
Refer to section 5.2.1 for more information.

automatically detect it. Verify that parameters F-11 (gain) and F-12 (offset) are set
correctly before starting the drive.
4.5Preparing the Motor
Follow these guidelines when preparing to install the motor:
• Verify that the motor is the appropriate size to use with the drive.
• Verify that the total motor lead length does not exceed the values given in section
3.2.4.
• Follow the instructions in the motor instruction manual when installing the motor.
SP500 AC Drive Installation and Operation Manual Version 3.1

may result if this procedure is not followed.
Wiring the Drive
Function loss control wiring connects to terminals 10 and 11. See figures 5.5 through
5.7. Typically, a function loss input is a maintained, normally-closed pushbutton.
A signal must be present at terminal 10 for the drive to run. A factory-installed jumper
connects terminals 10 and 11 which provides that signal. Remove this jumper if a
function loss input, a coast-stop pushbutton, or another external interlock (for
example, a motor thermostat) is used. Removing the jumper allows the drive to stop
when the contact is open.

Parameter Range:
Default Setting:
Step Size:
When F-00 = 0, the drive responds to sequencing commands (start, stop, forward,
reverse) from only the keypad.
When F-00 = 1, 2, or 3, the drive responds to sequencing commands from the
terminal strip. Note that the drive will respond to the stop command from the keypad
regardless of the value in this parameter.
Refer to the F-23 to F-25 Multi-Speed Presets parameter description for more
information about multi-speed presets.

F-05 Current Limit
This parameter limits
motor output torque
while it is running or
accelerating.
Parameter Range:
Default Setting:
Step Size:
When output current attempts to exceed the preset current limit, motor current will be
maintained or reduced, or the acceleration / deceleration time will be extended. If
current limit is set too low or too high relative to the required load, an overcurrent fault
may occur (OC will be displayed).
F-06 Manual Torque Boost
This parameter sets
the percentage of
output voltage boost at
zero frequency.
Parameter Range:
Default Setting:
Step Size:
Torque boost offsets the voltage drop of the AC motor at low speeds. For high friction
loads or high inertia loads, a high starting torque level may be needed. Manual torque
boost is only effective at speeds lower than one-half of the motor’s base frequency.
See figure 8.1.
When adjusting this parameter, start with the default setting of 2% and gradually
increase the value until motor operation is satisfactory. If torque boost is set too high
relative to the load and acceleration rate, an overcurrent fault may occur (OC will be
displayed).

The value to enter into F-08 is the maximum value (in RPM, hertz, or any other
engineering unit) to be displayed when the drive is running at base speed (F-07).
Display Scaling Examples
Example 1: Assume that an application requires the display show 1750 RPM when the drive is running
at a base speed of 60 Hz. The RPM display is scaled according to the following equation:

Example 2: Assume the application requires the display show 20 feet per minute for a conveyor (or 20
gallons per minute for a pump) when the motor is running at base speed (F-07= 60 Hz). Enter 20 in
parameter F-08 to scale the display.
At 30 Hz, the display will show 10 feet (or gallons) per minute:

F-09 Configurable Output Relay Select
This parameter
specifies the type of
status indication the
output relay contacts
provide (terminals 14,
15, and 16 on the drive
terminal strip).
.
Parameter Range:
Default Setting:
Step Size:
If F-09 = 0, the output is energized only when the RUN LED is on.
If F-09 = 1, the output remains energized until the fault is cleared by pressing the
STOP/RESET key (in local operation) or by using the remote IET reset signal (for
remote operation).
If F-09 = 2, the output is energized when the drive is running and at speed.
F-10 Carrier Frequency
This parameter selects
the drive’s carrier
frequency.
Parameter Range:
Default Setting:
0 = Output relay is energized to show state of drive
running.
1 = Output relay is energized to show state of active fault
(IET).
2 = Output relay is energized to show state of drive
running at speed.

N/A
4 = 4 kHz Carrier frequency
6 = 6 kHz Carrier frequency
8 = 8 kHz Carrier frequency

Step Size:
The carrier frequency controls the width of the pulse and keeps the current smooth to
the motor. This parameter can compensate for acoustic noise, heating, and other
current problems by adjusting the switching frequency of the transistors in the inverter
section.
Keeping the carrier frequency at 4kHz maximizes the continuous power rating of the
drive with, generally, an acceptable acoustic noise level from the motor. Increasing the
carrier frequency reduces the acoustic noise, but in some applications this can result
in derating of the drive output amps. (Refer to table 2.2 for the derated ratings at the
various carrier frequencies).
F-11 Remote Reference Gain
This parameter scales
the maximum remote
speed reference to
match external
equipment.
Parameter Range:
Default Setting:
Step Size:
Normally, the maximum speed reference (the amount of reference at maximum speed,
F-04) is either 10 VDC or 20 mA. The reference gain is used to scale the speed
reference to another value (for example, 9.5 VDC or 19 mA). Enter the parameter
value in percent of full scale reference.

If the remote speed reference is 0 to 20 mA and the maximum reference required is
19.2 mA, scale as follows:
To calculate the scaled reference if you are using a 0 to 10 VDC remote reference,
use the following equation:

F-12 Remote Reference Offset
This parameter scales
the remote speed
reference (0 to 10VDC
or 0 to 20 mA) to a
minimum value.
Parameter Range:
Default Setting:
Step Size:
Typically, the value of the minimum speed reference (the amount of reference at
minimum speed, F-03) is either 0 VDC or 0 mA. Enter the parameter value as a
percentage of the full scale reference to be offset from minimum speed.
To calculate the scaled minimum reference, use the following equation:

F-12 to obtain minimum speed with minimum analog input as follows:
Example 2: If the remote analog input speed reference is 0 to 10 VDC (J6 set on
terminals 1 and 2), and the available signal is offset 0.4 VDC, use F-12 to obtain

If the fault occurs again, the drive decrements the number of auto-restart attempts,
counts down the auto-restart time again, and continues the auto-restart process. If the
drive faults on all of these attempts, it remains in the faulted state and displays the
fault code for the fault it is trying to clear.
If the Stop/Reset input is asserted during the countdown, the auto-restart procedure is
cancelled and the fault is latched.
If a fault occurs that is auto-restartable and other faults are active that are not autorestartable, the auto-restart function will be disabled until all faults are cleared.
When F-26 ≠ 0, the drive logs the first occurrence of a fault in the fault log. Any
subsequent occurrence of that fault while attempting to restart the drive will not be
logged.

CHAPTER 9
Troubleshooting Reference
ATTENTION:Only qualified electrical personnel familiar with the
construction and operation of this equipment and the hazards involved
!
The SP500 drive is monitored by internal diagnostics. If a fault occurs, the drive
displays a two-digit fault code to identify the problem. A fault causes the drive to coast
to rest if it is running or prevents the drive from starting if it is stopped. The fault code
is also entered into the error log.
This chapter defines the fault codes and suggests actions to correct problems. It also
describes how to access and clear the error log.
Refer also to the F-26 (Auto-Restart Number of Attempts) parameter description in
chapter 8. This describes the drive’s reaction to drive faults if the auto-restart feature
is enabled (F-26 ≠ 0).

9.2Troubleshooting the Drive Using Fault Codes
Table 9.1 defines the fault codes for user-correctable faults, lists possible causes, and
suggests actions to take to correct the problem. All other faults require replacement
of the drive.
If a fault occurs, do the following:
Step 1. Try to clear the fault first by pressing the STOP/RESET key or asserting the
IET reset input (remote operation). If the fault reoccurs, continue with step 2.
Step 2. Refer to table 9.1 to identify the fault code and the possible causes.
Step 3. Perform the suggested corrective action(s).
Step 4. Clear the fault by pressing the STOP/RESET key or asserting the IET reset
input.

9.3Accessing and Clearing th e Error Log
Troubleshooting Reference
If a fault occurs, the drive displays a fault code and logs the fault code into the error
log. If more than one fault occurs, the first fault flashes on the display and the
subsequent faults (up to two) are logged in the error log. After three faults, no
subsequent faults are logged.
The faults in the error log are numbered sequentially. For example, if an overcurrent
fault occurred first followed by a thermal overload fault, the error log would read 1-OC,
2-OL.
The last fault to occur appears first when the error log is accessed. For example, if the
last fault to occur was a low bus fault, and the error log contained three entries, the
error log would display 3-LU when the error log is accessed.
