Regenerative Drives
Non-regenerative, variable speed DC drives control current and
speed to a motor in one direction only. The direction of current
flow is in the same direction as the motor rotation. This is
commonly described as Single Quadrant operation. (Quadrants 1
or 3 depending on your direction of rotation-see Figure 1).
Non-regenerative drives cannot oppose an overhauling load with
reverse torque, nor decelerate a load faster than coasting to a
lower speed. Dynamic braking with an external brake resistor
can be added to accomplish these things; however, it would
require the use of an external switch.
Regenerative drives, however, can operate in all four quadrants of
operation. They are able to control motor speed and current in
both directions simultaneously. Thus, regenerative drives can
reverse a motor, oppose an overhauling load and decelerate a load
faster than it would take to coast to a lower speed–all without any
external contactors or switches.

NRGD–4Q Drives
Minarik’s NRGD–4Q Series drives are four-quadrant, full-wave,
regenerative PWM drives. These open-chassis drives come with
the following features:
Low power consumption.
The NRGD series consume 30% less power than typical analog
PWM drives, and 50% less power than typical SCR drives.
Four-quadrant ACCEL/DECEL.
The ACCEL trimpot determines the time the motor takes to ramp
from a lower to a higher speed independent of direction. The
DECEL trimpot determines the time the motor takes to ramp
down from higher to lower speed independent of direction.
Pulse width modulation.
Lower form factor than SCR drives (1.10 versus 1.37) throughout
the motor speed range. Motor runs with greater efficiency and
less maintenance.
Four-quadrant regenerative operation.
See Regenerative drives section on the preceding pages.
Regenerative braking.
When used with an external dump circuit, the drive brakes along
user-adjusted deceleration profile. No contactors required and no
electromechanical components to overheat or wear out.

NRGD-4Q Drives
Fast brake/inhibit.
Active braking as fast as user-adjusted current limit allows.
Enable/Disable.
Turns off the output stage, allowing the motor to coast to a stop.
Cage-clamp terminals.
Quicker and easier wiring than screw terminals.
Plug reversing.
Quickly switch from forward to reverse without contactors.
Autoranging dual voltage input
Power the drive with either 120 VAC or 240 VAC.
Tachogenerator feedback option.
Improve the speed regulation from approximately 1% (armature
feedback) to 0.1% with tachogenerator feedback.
Diagnostic LEDs.
Green POWER ON and red FAULT LEDs allow easy visual
inspection of the drive status.
User adjustable trimpots.
Calibrate the drive precisely to your application needs with the
nine trimpots described in the Calibration section (starting on
page 31).

Installation
Mounting
Warning
Do not install, rewire, or remove this control with line
voltage applied. Doing so may cause fire or serious injury.
Make sure you have read and understood the Safety
Warnings before attempting installation.
• Drive components are sensitive to electrostatic fields. Avoid
direct contact with the circuit board. Hold drive by the chassis
only.
• Protect the drive from dirt, moisture, and accidental contact.
Provide sufficient room for access to the terminal block and
calibration trimpots.
• Mount the drive away from heat sources. Operate the drive
within the specified ambient operating temperature range.
• Prevent loose connections by avoiding excessive vibration of
the drive.
• Mount drive with its board in either a horizontal or vertical
plane. Six 0.19 in. (5 mm) wide slots in the chassis accept #8
pan head screws. Fasten either the large base or the narrow
flange of the chassis to the subplate.
• The chassis must be earth grounded. Use a star washer beneath
the head of at least one of the mounting screws to penetrate the
anodized chassis surface and to reach bare metal.

Shielding guidelines
Warning
Under no circumstances should power and logic leads be
bundled together. Induced voltages can cause unpredictable
behavior in any electronic device, including motor controls.
As a general rule, Minarik recommends shielding of all
conductors.
If it is not practical to shield power conductors, Minarik
recommends shielding all logic-level leads. If shielding is not
practical, the user should twist all logic leads with themselves to
minimize induced noise.
It may be necessary to earth ground the shielded cable. If noise is
produced by devices other than the drive, ground the shield at the
drive end. If noise is generated by a device on the drive, ground
the shield at the end away from the drive. Do not ground both
ends of the shield.
If the drive continues to pick up noise after grounding the shield,
it may be necessary to add AC line filtering devices, or to mount
the drive in a less noisy environment.
Logic wires from other input devices, such as motion controllers
and PLC velocity controllers, must be separated from power lines
in the same manner as the logic I/O on this drive.

Heat sinking
NRGD05-series drives do not require an external heat sink.
NRGD10-series drives require an external heat sink kit, part
number 223-0363, when the continuous armature current is above
5 amps DC.
Apply a thermally conductive heat sink compound (such as Dow
Corning® 340 Heat Sink Compound) in a thin layer between the
drive chassis and heat sink surface for optimum heat transfer.

Line fusing
Protect all Minarik drives with AC line fuses. Use fast acting AC
line fuses rated for 250 volts, and approximately 150% – 200% of
the maximum armature current. Fuse only the “hot” side of the
AC line (L1) if using 120 VAC line voltage. See Table 1 below
for recommended line fuse sizes.

Speed adjust potentiometer installation
Warning
Be sure that the potentiometer tabs do not make contact with
the potentiometer enclosure. Grounding the input will cause
damage to the drive.
Mount the speed adjust potentiometer through a 0.38 in. (10 mm)
hole with the hardware provided (Figure 4). Install the circular
insulating disk between the panel and the 10K ohm speed adjust
potentiometer. Twist the speed adjust potentiometer wire to avoid
picking up unwanted electrical noise. If speed adjust
potentiometer wires are longer than 18 in. (457 mm), use shielded
cable. Keep speed adjust potentiometer wires separate from power
leads (L1, L2, A1, A2).

Connections
Warning
Do not install, remove, or rewire this equipment with
power applied. Failure to follow this warning may result in
fire, explosion, or serious injury.
Minarik strongly recommends the installation of a master
power switch in the voltage input line, as shown in
Figure 5, page 14. The switch contacts should be rated at a
minimum of 200% of motor nameplate current and 250
volts.
Power, fuse and motor connections
Connect the power input leads, an external line fuse and a DC
motor to TB501 on the drive’s printed circuit board (PCB) as
shown in Figure 5, page 14.
Motor
Minarik drives supply motor voltage from A1 and A2 terminals.
It is assumed throughout this manual that, when A1 is positive
with respect to A2 , the motor will rotate clockwise (CW) while
looking at the output shaft protruding from the front of the motor.
If this is opposite of the desired rotation, simply reverse the
wiring of A1 and A2 with each other.

With line voltage disconnected, connect a DC motor armature to
PCB terminals A1 and A2 as shown in Figure 5. Ensure that the
motor voltage rating is consistent with the drive’s output
voltage.
Power input
Warning
Do not install, remove, or rewire this equipment with
power applied. Failure to follow this warning may result in
fire, explosion, or serious injury.
Minarik strongly recommends the installation of a master
power switch in the voltage input line, as shown in
Figure 5, page 14. The switch contacts should be rated at a
minimum of 200% of motor nameplate current and 250
volts.
Connect the AC line power leads to TB501 terminals L1 and L2,
or to a single-throw, double-pole master power switch
(recommended).
Line fuse
With line voltage disconnected, wire an external line fuse
between the stop switch (if installed) and the L1 terminal on
terminal board TB501. An additional line fuse should be installed
on L2 if the input voltage is 240 VAC. The line fuse(s) should be
rated at 250 volts and 150 - 200% of maximum motor nameplate
current. Refer to the line fuse chart on page 10 for fuse ratings.

Optional speed adjust potentiometer connections
The motor can operate in one direction (unidirectionally) or two
directions (bidirectionally) depending on how the speed adjust
potentiometer is connected to the drive.
Connect the speed adjust potentiometer as shown in Figure 7a for
bidirectional operation. The motor shaft does not rotate when the
wiper is in the center position. Turning the wiper CW from the
center causes the motor to rotate in one direction, while turning
the wiper CCW from center causes rotation in the opposite
direction.
Connect the speed adjust potentiometer as shown in Figure 7b for
unidirectional operation in the forward direction.
Connect the speed adjust potentiometer as shown in Figure 7c for
unidirectional operation in the reverse direction.
Refer to the Application Notes for additional speed adjust

Regen dump circuit connections
Warning
Minarik strongly recommends the installation of an extenal
regen dump circuit if you plan to use regenerative braking.
This will help avoid damage to the motor or drive.
The external regen dump circuit reduces the voltage across the
bus capacitor when it reaches a factory-set trip point.
As the drive regeneratively brakes, it returns excess voltage to the
bus capacitor, where it is stored until it can be discharged. When
the regen dump circuit detects excess bus voltage, it redirects or
“dumps” the excess voltage through a shunt resistor network,
safely discharging the bus capacitor. Bus capacitor maximum
working voltage ratings are 200 VDC for 120 VAC drives and
400 VDC for 240 VAC drives.
Please contact your Minarik representative for more information
on changing the dump circuit’s regen dump trip setting. Refer to
Figure 8, page 21, for regen dump circuit connections.

Operation
Warning
Dangerous voltages exist on the drive when it is powered,
and up to 30 seconds after power is removed and the motor
stops. BE ALERT. High voltages can cause serious or fatal
injury. For your safety, use personal protective equipment
(PPE) when operating this drive.
Do not change jumper settings with power applied. Remove
line voltage or disable the drive before changing jumper
settings. Failure to follow these instructions may result in
damage to the drive or motor or serious injury.
Before applying power:
•
Verify that no conductive material is present on the printed
circuit board.
•
Ensure that all jumpers are properly set.

Startup and shutdown
To start the drive:
1. Turn the speed adjust potentiometer full counterclockwise
(CCW). If the speed adjust potentiometer is wired for
bidirectional operation, set the pot to its center of travel. If
the drive is following a voltage signal, set the voltage signal
to 0 VDC.
2. Apply AC line voltage.
3. Slowly advance the speed adjust potentiometer clockwise
(CW). If the drive is following a voltage signal, slowly
increase the voltage signal. The motor slowly accelerates as
the potentiometer is turned CW, or the voltage signal is
increased. Continue until the desired speed is reached.
4. Remove AC line voltage from the drive to coast the motor to
a stop.
If the motor or drive does not perform as described, disconnect
the AC line voltage immediately. Refer to the Troubleshooting
section for further assistance.

Operation
Starting and stopping methods
Warning
Decelerating to minimum speed, regenerative braking, or
coasting to a stop is recommended for frequent starts and
stops. Do not use any of these methods for emergency
stopping. They may not stop a drive that is malfunctioning.
Removing AC line power (both L1 and L2) is the only
acceptable method for emergency stopping.
For this reason, Minarik strongly recommends installing
an emergency stop switch on both the L1 and L2 inputs
(see Figure 5, page 14).
Frequent decelerating to minimum speed or regenerative
braking produces high torque. This may cause damage to
motors, especially gearmotors that are not properly sized for
the application.
Minarik strongly recommends the installation of an external
regen dump circuit if you plan to use the NRGD’s
regenerative braking capability. This will help avoid damage
to the motor and/or drive. Refer to page 20 for information
on connecting an external regen dump circuit.
Automatic restart upon power restoration
After a one-second time delay, all drives automatically run to set
speed when power is applied and the ENABLE input is jumpered.

An alternative is to install a single-pole, single- throw switch
between the INH and COM terminals. Close the switch to
decelerate to minimum speed at a rate controlled by the
CURRENT LIMIT trimpot. Open the switch to accelerate the
motor to set speed.
ENABLE/DISABLE switch

Calibration
Warning
Dangerous voltages exist on the drive when it is powered,
and up to 30 seconds after power is removed and the motor
stops. When possible, disconnect the voltage input from the
drive before adjusting the trimpots. If the trimpots must be
adjusted with power applied, use insulated tools and the
appropriate personal protection equipment. BE ALERT.
High voltages can cause serious or fatal injury.
NRGD–4Q drives have nine user-adjustable trimpots. Each drive
is factory calibrated to its maximum horsepower rating. Readjust
the calibration trimpot settings to accommodate lower horsepower
motors.
With the exception of the TACH trimpot, all adjustments increase
with CW rotation, and decrease with CCW rotation. The TACH
trimpot increases with CCW rotation, and decreases with CW
rotation. Use a non-metallic screwdriver for calibration. Each
trimpot is identified on the printed circuit board.

11. Set the RUN/BRAKE switch to RUN, or remove the jumper
between the RB and COM terminals of terminal board
TB502.
12. Apply line voltage to the drive. The green POWER LED
shall light.
13. Set the ENABLE/DISABLE switch to ENABLE, or insert a
jumper between the ENBL and COM terminals of terminal
board TB502. The red RUN LED shall light when the drive
is enabled.
Calibrate the drive trimpots as follows.
BALANCE (BAL)
The balance setting corrects for a small offset voltage which
could be applied to the motor while the drive is in BRAKE mode.
This voltage may cause the motor shaft to continue to rotate even
after the drive and motor have been braked.
To calibrate BAL:
1. Set the BAL trimpot to the middle of its travel.
2. Set the speed adjust potentiometer or analog voltage signal to
minimum speed.
3. Apply input power.
4. Set the speed adjust potentiometer or analog voltage signal for
maximum forward speed. The motor should run at maximum
speed.
5. Set the RUN/BRAKE switch to BRAKE. If no switch is
installed, short the COM and RB terminals of connector
TB502. The motor should brake to a stop.

6. If the motor shaft does not stop, but slowly rotates after
braking, adjust the BAL trimpot either CW or CCW
(depending on the direction of motor shaft rotation) until the
motor shaft comes to a stop.
OFFSET
Warning
The OFFSET trimpot is used to provide low-speed
regulation for certain drives. It is calibrated at the factory
and should not require adjustment. Please consult your
Minarik representative for more information before adjusting
this trimpot.
The OFFSET setting adjusts the zero offset voltage in the internal
velocity loop. This affects the gain circuit which controls motor
regulation.
To calibrate OFFSET:
1. Set the speed adjust potentiometer or analog voltage signal to
zero speed and apply input power. If in unidirectional mode,
set the speed adjust potentiometer fully CCW. If in
bidirectional mode, set the speed adjust pot to midrange or
50%.
2. Apply line voltage and observe motor behavior.
3. If the motor shaft “creeps”, i.e., slowly rotates with no signal
applied, adjust the OFFSET trimpot until the shaft stops
rotating.

MAXIMUM SPEED (MAX SPD)
The MAX SPD setting determines the maximum motor speed
when the speed adjust potentiometer, or voltage input signal is set
for maximum forward speed. It is factory set for maximum rated
motor speed.
To calibrate MAX SPD:
1. Set the MAX SPD trimpot full CCW.
2. Set the speed adjust potentiometer or voltage input signal for
maximum forward speed.
3. Adjust the MAX SPD trimpot until the desired maximum
forward speed is reached.
TACHOGENERATOR (for use with tachogenerator
feedback only)
Calibrate the TACH setting only when a tachogenerator is used.
The TACH setting determines the degree to which motor speed is
held constant as the motor load changes.
To calibrate the TACH trimpot:
1. Connect the tachogenerator to terminal SO502. The polarity is
“+” for T1 and “–” for T2 with the motor running in the
forward direction. The motor will run in the forward direction
when the voltage at terminal A1 is more positive than A2.

2. Set ARM/TACH FEEDBACK jumpers J502 and J503 for
armature feedback. Refer to Figures 10 (pg. 24) and 11 (pg.
25) for jumper locations.
3. Run the motor at full speed. Measure the armature voltage
across A1 and A2 using a voltmeter.
4. Run the motor at either minimum speed or zero speed.
5. Remove AC line voltage.
6. Set ARM/TACH FEEDBACK jumpers J502 and J503 for
tachogenerator feedback.
7. Set the TACH VOLTAGE jumper to the correct
tachogenerator voltage range.
8. Apply AC line voltage.
9. Set the IR COMP trimpot full CCW.
10. Set the TACH trimpot full CW.
11. Run the motor at full speed.
12. Adjust the TACH trimpot until the armature voltage is the
same value as the voltage measured in step 3.
Check that the tachogenerator is properly calibrated. The motor
should run at the same set speed when the ARM/TACH
FEEDBACK jumpers are set to either armature or tachogenerator
feedback.

REGULATION (IR COMP)
The IR COMP trimpot (also known as regulation) determines the
degree to which motor speed is held constant as the motor load
changes. It is factory set for optimum motor regulation at
maximum rated horsepower.
To calibrate IR COMP (exact calibration):
1. Turn the IR COMP trimpot full CCW.
2. Set the speed adjust potentiometer or voltage input signal until
the motor runs at midspeed without load (for example, 900
RPM for an 1800 RPM motor). Measure the motor speed with
a hand held tachometer.
3. Load the motor armature to its full load armature current
rating. The motor should slow down.
4. While keeping the load on the motor, rotate the IR COMP
trimpot until the motor runs at the speed measured in step 2.
To calibrate IR COMP (approximate calibration):
If the motor does not maintain set speed as the load changes,
gradually rotate the IR COMP trimpot CW. If the motor oscillates
around the set speed (overcompensation), then IR COMP was
adjusted too high or too far CW. Turn the IR COMP trimpot
slowly CCW to stabilize the motor and regulate set speed. Repeat
this adjustment if necessary.

CURRENT LIMIT
Warning
Although CURRENT LIMIT is set to 120% of drive
nameplate current rating, continuous operation beyond that
rating may damage the motor. If you intend to operate
beyond the rating, contact your Minarik representative for
assistance.
1. With no power applied to the drive, connect a DC ammeter in
series with the motor armature.
2. Set the CURRENT LIMIT trimpot to full CCW.
3. Carefully lock the motor armature. Ensure that the motor is
firmly mounted.
4. Apply line power. The motor should be stopped.
5. Set the speed potentiometer or reference signal to maximum
speed. The motor should remain stopped.
6. Slowly rotate the Forward torque trimmer pot clockwise (CW)
until the ammeter reads 120% of maximum motor armature
current.
7. Set the speed adjust potentiometer or reference signal to zero
speed.
8. Remove power from the drive.
9. Remove the lock from the motor shaft.

ACCELERATION (ACCEL)
The ACCEL setting determines the time the motor takes to ramp
to a higher speed in either direction. ACCEL is factory set for the
fastest acceleration time (full CCW).
To calibrate ACCEL:
1. Set the speed adjust potentiometer or voltage input signal for
zero speed. The motor should run at zero (or minimum)
speed.
2. Set the speed adjust potentiometer or voltage input signal to
maximum forward speed, and measure the time it takes the
motor to go from minimum to maximum speed.
3. If the time measured in step 2 is not the desired acceleration
time, turn the ACCEL trimpot CW for a slower acceleration
time, or CCW for a faster acceleration time. Repeat steps 1
through 3 until the acceleration time is correct.

DECELERATION (DECEL)
The DECEL setting determines the time the motor takes to ramp
to a lower speed in either direction. DECEL is factory set for the
shortest deceleration time (full CCW).
To calibrate DECEL:
1. Set the speed adjust potentiometer or voltage input signal for
maximum forward speed. The motor should run at maximum
speed.
2. Set the speed adjust potentiometer or voltage input signal for
minimum speed and measure the time it takes the motor to go
from maximum to minimum speed.
3. If the time measured in step 2 is not the desired deceleration
time, turn the DECEL trimpot CW for a slower deceleration
time, or CCW for a faster deceleration time. Repeat steps 1
through 3 until the deceleration time is correct.

LOOP GAIN (LOOP)
Warning
The LOOP trimpot is used to provide additional regulation
for certain low-horsepower, high-inductance motors. It is
unused in most applications and is factory set to zero
(full CCW). Please consult your Minarik representative for
more information before adjusting this trimpot.
If calibration is necessary, perform the following procedure:
1. Apply input power and set the speed adjust pot to
approximately 50% of maximum motor speed. If an input
signal is used, set the signal to approximately 50% of
maximum.
2. Adjust the LOOP trimpot slowly CW until the motor becomes
unsteady under load. A hum from the motor may be audible
at this point.
3. Slowly adjust the LOOP trimpot CCW until the motor
stabilizes and the hum (if any) is quieted. At this point, the
LOOP GAIN trimpot is adjusted to its maximum acceptable
setting and should need no further adjustment.
Calibration sequence conclusion
1. Set the speed adjust potentiometer or analog input signal to
zero speed.
2. Remove power to the drive and motor. The drive is now
calibrated for nominal operation.

Troubleshooting
Diagnostic LEDs
NRGD05 and NRGD10 series drives are equipped with the
following diagnostic LEDs to aid in troubleshooting. Refer to
Figure 21 (NRGD05) and Figure 22 (NRGD10) for diagnostic
LED locations.
POWER
The green POWER LED lights when AC line voltage is applied
to the drive (the drive’s power supply is active).
RUN
The red RUN LED lights when the drive is enabled.
CURRENT LIMIT (CL/FTL)
The red CURRENT LIMIT LED lights when drive output current
exceeds the threshold set by the CURRENT LIMIT trimpot.
PEAK
The red PEAK LED lights when the drive’s output to the regen
dump circuit exceeds the dump circuit’s maximum input voltage.
When this condition exists, the NRGD drive will switch off its
power control components, coasting the motor to a stop.
However, once the threshold is cleared (bus voltage drops below
the PEAK value), the power components will begin to switch on
at a rate controlled by the speed adjust pot or voltage signal input.
This may lead to sudden, undesired motor restarts or intermittent
motor operation. For this reason, if the PEAK LED lights, always
set the speed adjust pot or input signal to zero speed, then restart
the drive.

Unconditional Warranty
A. Warranty
Minarik Corporation (referred to as “the Corporation”) warrants that its products will be free from
defects in workmanship and material for twelve (12) months from date of manufacture thereof.
Within this warranty period, the Corporation will repair or replace such products that are returned
to Minarik Corporation, 901 East Thompson Avenue, Glendale, CA 91201-2011 USA.
This warranty shall not apply to any product that has been repaired by unauthorized persons.
The Corporation is not responsible for removal, installation, or any other incidental expenses
incurred in shipping the product to and from the repair point.
B. Disclaimer
The provisions of Paragraph A are the Corporation’s sole obligation and exclude all other
warranties of merchantability for use, express or implied. The Corporation further disclaims any
responsibility whatsoever to the customer or to any other person for injury to the person or
damage or loss of property of value caused by any product that has been subject to misuse,
negligence, or accident, or misapplied or modified by unauthorized persons or improperly
installed.
C. Limitations of Liability
In the event of any claim for breach of any of the Corporation’s obligations, whether express or
implied, and particularly of any other claim or breech of warranty contained in Paragraph A, or of
any other warranties, express or implied, or claim of liability that might, despite Paragraph B, be
decided against the Corporation by lawful authority, the Corporation shall under no
circumstances be liable for any consequential damages, losses, or expense arising in
connection with the use of, or inability to use, the Corporation’s product for any purpose
whatsoever.
An adjustment made under warranty does not void the warranty, nor does it imply an extension
of the original 12-month warranty period. Products serviced and/or parts replaced on a nocharge basis during the warranty period carry the unexpired portion of the original warranty only.
If for any reason any of the foregoing provisions shall be ineffective, the Corporation’s liability for
damages arising out of its manufacture or sale of equipment, or use thereof, whether such
liability is based on warranty, contract, negligence, strict liability in tort, or otherwise, shall not in
any event exceed the full purchase price of such equipment.
Any action against the Corporation based upon any liability or obligation arising hereunder or
under any law applicable to the sale of equipment or the use thereof, must be commenced
within one year after the cause of such action arises.
