DV-300 Adjustable Speed Drives
1. PRECAUTIONS AND WARNINGS
According to the EEC standards the DV300 and
accessories must be used only after checking that the
machine has been produced using those safety devices
required by the 89/392/EEC set of rules, as far as the
machine industry is concerned.
Drive systems cause mechanical motion. It is the responsibility of the user to insure that any such motion
does not result in an unsafe condition. Factory provided
interlocks and operating limits should not be bypassed
or modified.
WARNING - ELECTRICAL SHOCK AND BURN
HAZARD:
When using instruments such as oscilloscopes to work
on live equipment, the oscilloscope’s chassis should
be grounded and a differential amplifier input should
be used. Care should be used in the selection of probes
and leads and in the adjustment of the oscilloscope so
that accurate readings may be made. See instrument
manufacturer’s instruction book for proper operation
and adjustments to the instrument.
WARNING - FIRE AND EXPLOSION HAZARD:
Fires or explosions might result from mounting drives
in hazardous areas such as locations where flammable
or combustible vapors or dusts are present. Drives
should be installed away from hazardous areas, even if
used with motors suitable for use in these locations.
Improper installation of motors or drives may therefore
cause the failure of the device as well as serious injury
to persons or material damage.
Follow the instructions given in this manual and observe
the local and national safety regulations applicable.
CAUTION:
Do not connect power supply voltage that exceeds the
standard specification voltage fluctuation permissible.
If excessive voltage is applied to the Drive, damage to
the internal components will result.
CAUTION:
Do not operate the drive without the ground wire
connected. The motor chassis should be grounded to
earth through a ground lead separate from all other
equipment ground leads to prevent noise coupling.
The grounding connector shall be sized in accordance
with the NEC or Canadian Electrical Code. The
connection shall be made by a UL listed or CSA certified
closed-loop terminal connector sized for the wire gauge
involved. The connector is to be fixed using the crimp
tool specified by the connector manufacturer.
CAUTION:
Do not perform a megger test between the Drive
terminals or on the control circuit terminals.
WARNING - STRAIN HAZARD:
Improper lifting practices can cause serious or fatal
injury . Lift only with adequate equipment and trained
personnel.
WARNING:
Replace all covers before applying power to the drive.
Failure to do so may result in death or serious injury.
WARNING:
Adjustable speed drives are electrical apparatus for use
in industrial installations. Parts of the drives are
energized during operation. The electrical installation
and the opening of the device should therefore only be
carried out by qualified personnel.
—————— Quick Start up guide ——————
CAUTION:
Because the ambient temperature greatly affects drive
life and reliability, do not install the drive in any location
that exceeds the allowable temperature. Leave the
ventilation cover attached for temperatures of 40° C
(104° F) or below.
CAUTION:
If the drive’s Fault Alarm is activated, consult the
TROUBLESHOOTING section of the instruction book,
and after correcting the problem, resume operation. It
is not recommended to reset the alarm automatically
by external sequence, etc.

GEH-6129
CAUTION:
Be sure to remove the desicant dryer packet(s) when
unpacking the Drive. (If not removed these packets may
become lodged in the fan or air passages and cause the
Drive to overheat).
CAUTION:
The Drive must be mounted on a wall that is constructed
of heat resistant material. While the drive is operating,
the temperature of the Drive’s cooling fins can rise to a
temperature of 90° C (194°F).
NOTE! The terms “converter”, “controller” and
“drive” are sometimes used interchangably
throughout the industry. W e will use the term
“drive” in this document
NOTE! 1. Never open the device or covers while the
AC input power supply is switched on.
Minimum time to wait before working on the
terminals or inside the device is listed in the
instruction book
2. Do not touch or damage any components
when handling the device. The changing of
the isolation gaps or the removing of the
isolation and covers is not permissible. If the
front plate has to be removed because of a
room temperature higher than 40 degrees, the
user has to ensure that no accidental contact
with live parts may occur.
3. Protect the device from extreme
environmental conditions (temperature,
humidity, shock etc.)
4. No external voltage should be connected
to the output of the converter (terminals C &
D).
5. When engaging a running motor, the Auto
capture function (Auto capture in the ADD
SPEED FUNCT menu) must be activated.
6. Only an standard inductive DC motor load
should be connected to the output of the drive
(terminals C & D).
7. Always connect the Drive to the protective
ground (PE) via the marked connection
terminals (PE2) and the housing (PE1). The
discharge current to earth may be greater than
3.5 mA. A fixed (non disconnectable) ground
connection must be provided for this, to
comply with EN 50178 (VDE 0160). It is
aso recommended that the ground cable
should have a cross section of at least 10 mm
8. The electrical commissioning should only
be carried out by qualified personnel, who
are also responsible for the provision of a
suitable ground connection and a cable
protection for the power supply in accordance
with the local and national regulations. The
motor must be protected against overloads.
9. No dielectric tests using meggers or hi pots
should be carried out on the drive. A suitable
measuring instrument (internal resistance of
at least 10 kΩ/V) should be used for
measuring the signal voltages.
10.It is recommended to disconnect the drive
from the AC input feeder to prevent
unintentional running in the event of a failure,
even if the drive is disabled.
NOTE! The DV-300 operates from the inputs: start
and enable. If the enable input / signal is
removed, the start signal is not automatically
removed. Re establishing the enable signal
with the start signal already present can cause
motor rotation.
This guide highlights simplified steps to
program and tr oubleshoot the DV -300 drive.
In is intended to be used as a aid for trained
personnel, and to complement the DV-300
Instruction Book, after the drive is installed
in accordance with the DV-300 Instruction
Book.

2. PREFACE
DV-300 Adjustable Speed Drives
2a. Important Introduction
This startup guide is based on starting up the DV-300
out of the box from the factory , based on factory default
settings.
This guide will walk the user through sequential steps
and checkpoints for startup. It is recommended to follow
this guide sequentially without skipping steps unless
this guide instructs the user to do so.
Parameter menus and names will be shown in a keypad
screen symbol, for example:
SPEC FUNCTIONS
Save parameters
parameter names will also be shown in brackets [save
parameters]
2b. Drive Memory
There are two memories for drive parameters. One is
the active memory which is always the one currently
in use by the drive. The other is the permanent memory
which is the drive accesses on power up. This is the
ONL Y time when the drive looks at permanent memory .
All file uploads and downloads, all changes, etc. are
made only to the active memory and read from the active
memory. The only time permanent memory is used in
any way is that when it is booted into active memory
on power up, and when it is stored using the “Save
Parameters” command.
When parameters are changed during set up, the
changes are not permanent. The parameters changes
are temporarily used, but unless [SAVE
P ARAMETERS] is executed, after recycling power, the
changes are lost. This is an advantage to “experiment”
with a parameter change to see how the change works,
and not modify the permanent set-up.
As parameters are entered it is recommended to
occasionally save entered data. The [SAVE
PARAMETER]command is located at the end of the
START UP, TUNING, and under the SPEC
FUNCTIONS menu.
2c. Basic control wiring and starting
The terminal board inputs provide the user a hardwired
control means to sequence the drive.
For testing, the inputs can be wired using a local switch
box per the drawing below.
The actual control interface can be used if it has been
checked out, and is a convenient and reliable control
means.
11 12 13 14 15 16 18 19 20
11 - power supply common
12 - enable (close to activate)
13 - start (close to activate)
14 - fast stop (open to activate)
15 - external fault (open to activate)
16 - common for TB pts 11 -15
18 - + 24 V common
19 - + 24 VDC
20 - ground
After the control circuits are wired, and proven to
operate, repower the DV-300.
Close only the switch for EXTERNAL FAULT input.
Reset external drive fault with the keypad’s CANC key .
The default DV-300 configuration sets the control
inputs in a “digital” mode, which is for keypad and
PC control. In this mode, the terminal board inputs
must be connected to 24 VDC as well as commanded
from the keypad or PC.
This mode is set by parameter:
When this parameter is set to terminals, the terminal
board inputs control the drive.
When this parameter is set to
digital, the keypad,
PC, or bus controls the sequencing, but opening the
terminal board input will also cause the signal to
drop out.

3. PRE POWER CHECKS
3a. Grounds/grounding
DV-300 Adjustable Speed Drives
Verify an AC power ground wire exists from the incoming power / isolation transformer to the DV-300
input ground terminal.
Verify the ground lead of the DV-300 output terminal is
wired to the motor, or the motor is properly grounded.The
DV-300 power supply, terminal point 11, may be
referenced to ground through a different ground circuit,
or may be wired to the same ground by connecting terminal
point 11 to terminal point 10 or 20.
V erify the AC input leads, DC output armature and field
leads, and control wiring to and from the drive terminals
are not grounded.
Use a digital voltmeter or equivalent to take these
readings if the wiring is attached to the drive. Remember
that the 0V terminal may be intentionally grounded.
Isolated field wiring generally reads at least 2-3 MW
to ground.
3b. Meggering
Cabling must be disconnected or isolated from the DV 300 drive when meggered or hi potted. Drive damage
could result if this advice is not followed.
3c. Connections
Without applying power , double check all connections
and wire terminals to make sure they are tight.
V erify each connection is wired per wiring diagrams,
and are appropriate for the current and voltage
levels specified.

3d. motor data tabulation
Before commissioning, it is recommended to record the actual motor nameplate data. Also record gearbox, and
attached roll diameter, or any appropriate mechanical data that may be needed during setup.
This table may be used as a guide to record motor nameplate and application data

The value for RPM may be represented with two values, the first representing base speed , which is the rpm at
nameplate volts and nameplate field current.
A second RPM value, if shown, corresponds to rated top speed, which is achieved at rated nameplate volts, and
a weak field setting. The weak field setting would correspond to the second value of field amps.
For the nameplate below, base speed is 1750 rpm @ 3 amps field and top speed is 2300 rpm @ 1 amp field
Typical DC Motor Nameplate
HP (kW) 20 RPM 1750 / 2300 Volts 500
Arm Amps 32
Fld Amps 3.0 / 1.0 Fld ohms 25 C 72
Verify the motor data matches the drive power rating, output voltages, and required motor speed is achievable.
If files in the GE Control System Toolbox were predefined off-line, verify the entered data is correct before
downloading to the drive

3e. field current calibration dipswitch S14
The DV-300 regulation card is shipped with the field current feedback resistor dipswitches calibrated for the
maximum rating of the field package capacity for each size DV-300.This maximum field package rating is
incorporated in the DV- 300 catalog number.
For example: 6KDV3017Q4F
Compare the actual motor field data, recorded in step 3d., to the maximum rating of the field package
of the DV-300 model supplied (in the instruction book) , and to the field calibration dipswitch S14, as shown
below Table 3e1, 3e2, 3e3.
· For fixed field current operation, if the actual motor (base) field current = 10% of the maximum rating of the
field package it is required to calibrate the field current feedback scaling using dipswitch S14.
· For weak field operation, also referred to CEMF field control or crossover field control, if the actual top
speed motor field current = 10% of the maximum rating of the field package it is required to calibrate the
field current feedback scaling using dipswitch S14.
Calibration to the exact field current setting is not required, as long as the above conditions are met.
Calibration is not required if the field control is provided from a source other than the DV-300.
10D1 The 10 represents a 10 A field exciter.
Example:
For the nameplate below , base speed is 1750 rpm @ 2.9 amps field and top speed is 2300 rpm @ 2.1 amp field.
The motor is desired to run at 2300 rpm, so the minimum field is 1 amp.
Typical DC Motor Nameplate
HP (kW) 20 RPM 1750 / 3000 Volts 500
Arm Amps 32
Fld Amps 2.9 / .9 Fld ohms 25 C 72
For DV-300, 6KDV3035..., the field package is rated for 10 A. The motor is needed to run at 3000 rpm, so
requires a minimum field setting of .9 amps. .9 A is less than 10% of the 10 A default dipwitch setting therefore
it needs changed.
A good setting for field curr scaling is 3.0 amps, S14-5 = ON, all others = Off.
The parameter [field curr scaling] also needs set for 3.0 amps.

4. POWER UP CHECKS AND INITIAL CONFIGURING
4a. Don’t turn on power yet.....check power
input
GEH-6129
To load factory default settings, go to:
Make sure the AC incoming voltage at the input side of
the disconnect switch(s) is/are correct for the main
converter, field control (460 VAC max), and control
power (115 - 230 VAC).
Disconnect drive connectors from option cards DGF
and SBI ( LAN interface cards ) if supplied.
This will keep other potential sources of control and
referencing from interfering with the initial setup.
To make absolutely sure motor motion is not possible
from any source on initial power up, pull out the I/O
connectors for Regulator terminal board points 1 - 20.
If the DV-300 is much larger than the actual motor
rating, the default field current setting may be higher
than the actual motor field. T o prevent overloading and
heating of the motor field circuit in this situation, it
may be advisable to disconnect the field circuit
connector (with the wiring attached) until the calibrated
data is entered.
4b. Power up
If possible, turn control power on separately first, check
that everything looks OK visually.
If one single disconnect switch is provided , turn on
power at this time.
The keypad LED should show “external fault” if the
terminal board connector points 11-20 are pulled out.
If other faults are present, ignore them for now.

table.
Dipswitch S15 - 7 = off; identifies to the DV 300 firmware: 400 V European defaults
Dipswitch S15 - 7 = on; identifies to the DV 300: 460 V American defaults.
4c. Loading default settings
The DV-300 contains appropriate default settings for
typical 500 VDC GE motors, right out of the box.
If the drive has been powered before by persons
unknown, or the exact programming condition of the
drive is unknown, or for just getting a fresh
configuration start, executing a “load default”
parameters may be in order.
If the drive has been supplied from a third party as an
engineered package, many of the settings may be
already set, so loading default may be inappropriate.

Main commands
The terminal board inputs 12, 13, 14, and 15 must then
be connected to TB 19 (24 VDC), either through
jumpers, switches, or contacts.
It is recommended to have a switch wired from terminal
input 12 to 19 that is readily accessible to the user, so
under the drive can be stopped quickly during
commissioning.
CONFIGURATION
Main commands
When the self tune is complete , and only when the test
is complete, the drive will automatically set the
parameter [ST AR T UP\ Cur reg self tune] = OFF , enable
and start commands will be turned off.
The results of this test are temporarily stored in

7c. Checking current regulator performance using parameter Eint
While running the drive , monitor the parameter [Eint],
located under menu heading “Current Regulator”.
This measures an average internal current error.
Its value should be close to zero, but values dynamically
changing between -40 and 40 are acceptable.
The drive must have at least 30% load for this
reading to be considered as a valid performance
measurement.
If adjustments are needed, make small changes to the
parameter [Current Regulator \ Arm inductance] to fine
tune [Eint] to an acceptable value.

This parameter is found at keypad locations:
CONFIGURATION
Main commands
The drive can operate enable and start/stop control from
the keypad by setting parameter [main commands] =

—————— Quick Start up guide ——————
Analog outputs can be scaled for the desired voltage
output. A default scale value of 1.0 sets speed related
variables = 10 volts of parameter [speed base value] ,
and current related variables = 10 V of parameter [ full
load current ].
Analog inputs can also be scaled. A default scale value
of 1.0 sets speed related variables 100% of parameter
[speed base value] @ 10 volts input, and current related
variables 10 V = 100% of parameter [ full load current ].

When the enable signal becomes active in the drive,
speed and current regulators are released, but
referencing is not. External referencing into ramp
ref 1and 2, speed ref 1 and 2, or T curr ref 1 and 2
may cause the drive to output , and cause the motor

Fast stop Fast stop is initiated if terminal 14 is
DISconnected from + 15 to +30 VDC.
If mains command = digital , fast stop is initiated
if terminal 14 is DISconnected + 15 to +30 VDC
or fast stop is transitioned from 1 to 0 using a
LAN command, or using the PC configurator
Control Window.
Fast stop is a ramped stop to zerospeed. The fast
stop ramp is adjusted using parameters
stop control
RAMP\Quick stop\QStp delta speed and
RAMP\Quick stop\QStp delta speed. The default
setting is 1000 rpm/sec.
If mains commands = terminals , when fast stop is
initiated (by drop out of signal) the drive decelerates
according to the Qstp ramp rate.
If mains commands = digital , when fast stop is
initiated by opening terminal 14 (drop out of signal)
the drive decelerates according to the Qstp ramp rate.
For example, if enable, or the enable & start bus
signals are still picked up after fast stop is initiated
by disconnecting terminal 14, when the fast stop
input transitions back to 1 (picks back up), the drive
will continue to operate as per the enable and start
input states.
The fast stop signal also may be internally
interlocked with other DV-300 signals using the
stop control parameter.
External fault Is initiated if terminal 15 is
DISconnected from + 15 to +30 VDC.
The action of external fault is programmable by
Configuration\prog alarms\External fault. Default
programming of External fault disables the DV300 (coast stop) and causes a latched trip.

Alarm -> when lit, an alarm or trip condition is present.
Enable -> when lit, the enable command is active.
The actual Enable status can be controlled
internally by the DV -300 with the programming of
the Stop control parameter. Refer to section II.g.
for details on that parameter setting.
The input is commanded when terminal 12 is
connected + 15 to +30 VDC and mains commands

Ilimit -> when lit, the drive is in current limit, or torque
current limit.
Zero speed -> when lit, the drive speed feedback is
detected to be below the adjustable zero speed
threshold.
+ torque LED -> when lit, the LED signals that the
current feedback magnitude is in a direction to
provide positive motor output torque.
Under light load conditions, the LEDs may flicker
between + and - torque.
This is the speed regulator generating + and - torque
current to accurately regulate speed.
- torque LED -> when lit, the LED signals that the
current feedback magnitude is in a direction to
provide negative motor output torque.
