Series 2600/2610 Controllers control the operation of general purpose DC motors designed for use with
solid-state rectified power supplies. The motor may be shunt-wound, stabilized shunt-wound, or permanent mag­net. For maximum efficiency, the motor should be rated for operation from a NEMA Code K power supply.

BOOK0795-F

SECTION II

INSTALLATION

Before starting the installation, read this section thoroughly. In addition, a through review of the Ratings And
Specifications (Section VII) is recommended. The following installation guidelines should be kept in mind when
installing the controller.

INSTALLATION GUIDELINES

1. CONTROLLER MOUNTING - Controllers rated 1/6 - 3 HP may be mounted either vertically or hori-

zontally. Controllers rated at 5 HP may only be mounted vertically. Never mount the controller upside
down, immediately beside or above heat generating equipment, or directly below water or steam pipes.

The controller must be mounted in a location free of vibration.

Multiple controllers may be mounted side by side, as close to each other as the mounting feet will allow.
However, if a Model 2601 or 2602 Controller enclosure has Cover Hinges (Option 1638), 4 inches (102
mm) clearance must be provided on the hinged side of the enclosure to accommodate the swing of the
cover.

The minimum clearance at the top and bottom of the controller may be as narrow as the conduit fittings
allow.

2. ATMOSPHERE - The atmosphere surrounding the controller must be free of combustible vapors, chem­ical fumes, oil vapor, and electrically conductive or corrosive materials.

The air surrounding an enclosed controller must not exceed 40 degrees C (104 degrees F), and the air sur­rounding an open-chassis controller must not exceed 55 degrees C (131 degrees F). Minimum air tempera­ture is 0 degree C (32 degrees F) for enclosed and open-chassis controllers.

Model 2601 and 2602 Controllers (except 5 HP enclosed models) require a natural convection flow of air
over the pins on the back of the controller to dissipate the heat generated by the controller. Allow 4 inches
(102 mm) clearance on all sides from solid objects which block the flow of air to the pins.

3. CONTROLLER CONSTRUCTION - Series 2600/2610 controller bases are made of die-cast aluminum
with a powdered epoxy finish.

Series 2600/2610 Controller enclosures are totally enclosed, nonventilated, and comply with NEMA Type
4 and 12 standards. There is an oil resistant synthetic rubber gasket between the cover and base. Those
models with integral operator controls include flexible boots to seal the switches, and a seal for the
MOTOR SPEED potentiometer.

Series 2600 enclosure covers are molded of Noryl, which is not affected by most water-based solutions,
detergents, acids, and bases. However, the cover may be softened by heptane, acetone, and other haloge­nated and aromatic hydrocarbons, so install Series 2600 Controllers in a location free of these substances.

Series 2610 enclosure covers are made of a die-cast aluminum alloy.

3

BOOK0795-F

4. BRANCH CIRCUIT PROTECTION - The National Electrical Code requires that a two-pole fused dis­connect switch be installed in the AC line supply to the controller. Although an optional two-pole circuit
breaker (Option 1010) is available for Model 2601 Controllers, this circuit breaker should not be consid­ered as branch circuit protection. However, the existing branch circuit may already provide the required
protection. Refer to the National Electrical Code and local codes.

5. LINE SUPPLY - The controller should not be connected to a line supply capable of supplying more than
100,000 amperes short-circuit current. Short-circuit current can be limited by using an input supply trans­former of 50 KVA or less, or by using correctly sized current limiting fuses in the supply line ahead of the
controller. Do not use a transformer with less than the minimum transformer KVA listed in Table 9, page

33.

If rated line voltage is not available, a line transformer will be required. If the line supply comes directly
from a transformer, place a circuit breaker or disconnect between the transformer secondary and the con­troller. If power is switched in the transformer primary, transients may be generated which can damage the
controller. See Table 9 (page 33) for minimum transformer KVA.

Do not use power factor correction capacitors on the supply line to the controller.

A 12-joule metal oxide varistor (MOV) is connected across the controller terminals. If higher energy tran­sients are present on the line supply, additional transient suppression will be required to limit transients to
150% of peak line voltage.

When a 115 VAC line supply is used, connect the white (common) wire to Terminal L2 and connect the
remaining (hot) wire to Terminal L1.

6. ISOLATION TRANSFORMER - While not required, an isolation transformer can provide the following
advantages:

a. Reduce the risk of personal injury if high voltage drive circuits are accidently touched.

b. Provide a barrier to externally generated AC supply transients. This can prevent controller damage from
abnormal line occurrences.

c. Reduce the potential for damaging current if the motor armature, motor field, or motor wiring become
grounded.

7. GROUNDING - Connect the green or bare (ground) wire of the line supply to the ground screw located
near the top conduit entry hole in the controller base. Then ground the controller base by connecting the
ground screw to earth ground.

The motor frame and operator control stations must also be grounded.

Personal injury may occur if the controller, motor, and operator stations are not properly grounded.

8. WIRING PRACTICES - The power wiring must be sized to comply with theNational Electrical Code,

CSA, or local codes. Refer to the controller data label for line and motor current ratings.

Do not use solid wire

4

BOOK0795-F

Signal wiring refers to wiring for potentiometers, tachometer generators, and transducers. Control wiring
refers to wiring for operator controls. Signal and control wiring may be run in a common conduit, but not
in the same conduit with the power wiring. In an enclosure, nonshielded signal and control wiring must be
kept separated from power wiring and only cross at 90 degree angles.

If shielded wire (such as Alpha 2422 - two conductor, 2423 - three conductor, 2424 - four conductor) is
used for the signal and control wiring, connect the shields to chassis ground (ground screw on the control­ler base) and tape the opposite ends of the shields.

Two 3/4-14 NPT threaded holes are provided for conduit entry, one each in the top and bottom of the con­troller base.

9. OPTIONS - This equipment manual is for use with the basic controller. If options are installed in the con-

troller, they will be identified on the controller data label. The instruction sheets supplied with the options
should be reviewed before the controller is installed.

INSTALLING THE CONTROLLER

1. Remove the controller front cover (if used) by removing the four cover screws.

2. Check components in the controller for shipping damage. Report shipping damage to the carrier.

3. Check the controller and motor data labels to be sure the units are electrically compatible.

4. Be sure the controller has been calibrated correctly for the motor being used. Calibration is performed by

changing the position of a Jumper (J4) on the controller control board to comply with Table 3. To change
the position of Jumper J4, pull the jumper from the control board and then push it onto the appropriate two
pins on the board. For the location of J4, see Figure 22 (page 43) or Figure 23 (page 44) as applicable.

a. Select the position closest to the motor nameplate armature current rating.

5. Check the positions of Jumpers J1, J2, and J3 on the control board. For the locations of J1, J2, and J3, see

Figure 22 (page 43) or Figure 23 (page 44) as applicable. For a 230 VAC line supply and a 180V armature
motor, Jumper J1 must be in the 230V position, and Jumpers J2 and J3 must both be in the 180V position.
For a 115 VAC line supply, J1 must be in the 115V position, and J2 and J3 must be in the 90V position.

NOTE: If Option 1001 (Armature Contactor, Unidirectional), 1004 (Armature Contactor, Reversing), or

1775 (Signal Interface) is to be installed in the controller, do not offset the five-position plug
(supplied with the option) at Connector J1 on the control board. Do not confuse Connector J1
with Jumper J1. Refer to the Instruction Sheet (ISP0703, ISP0666, ISP0653, respectively) sup­plied with the option for connection instructions.

INITIAL STARTUP

1. Open the controller cover (if used) by removing the four cover screws.

2. Be familiar with all options installed in the controller by reviewing the instruction sheets supplied with the

options.

3. Be sure all wiring is correct and all wiring terminations are tightened securely.

4. Be sure the controller is calibrated correctly. See steps 4 and 5 under “Installing The Controller” on page 5.

5. Be sure the AC supply voltage to the controller agrees with the controller data label.

6. The potentiometers in the controller are factory adjusted as shown in Table 4. These settings will provide

satisfactory operation for most applications. If different settings are required, refer to “Adjustment Instruc­tions” starting on page 21.

7. If the controller has a cover, place it on the controller and secure it with the four cover screws.

8. Turn-on the AC supply to the controller.

9. Check motor rotation, as follows:

a. If a MOTOR SPEED potentiometer is used, turn it fully counterclockwise. If an external signal is used

for the speed reference, set it at minimum.

b. If a RUN-STOP-JOG switch is used, place it in RUN position. Otherwise, initiate a Run command.

c. Turn the MOTOR SPEED potentiometer clockwise or increase the speed reference signal, as applica-

ble. To stop the motor, place the switch in STOP position or initiate a Stop command, as applicable.

If the motor rotates in the wrong direction, turn-off the AC supply to the controller, and then interchange
the motor armature leads at the motor connection box or at the controller terminal board.

10. Refer to Section III, “Operation” for operating instructions.

SECTION III

OPERATION

POWER ON/OFF

To energize the drive, turn-on the AC supply voltage to the controller. When this occurs, the motor shunt
field energizes with rated field voltage, and potentially hazardous voltage is present at the motor armature termi­nals. These voltages can cause electric shock resulting in personal injury or loss of life.

If the AC supply is interrupted, and the controller is not set up for line starting, the motor will not restart
when the AC supply is restored until the controller is reset by initiating a Stop command and then a Start command.
If the controller is set up for line starting, and the AC supply is interrupted, the motor will restart when the AC sup­ply is restored, provided the external AC line contactor is pulled in.

RUN

If a RUN-STOP-JOG switch is used, place the switch in RUN position. Otherwise, initiate a Run command.
A Run command will accelerate the motor to the setting of the MOTOR SPEED potentiometer or external speed
reference signal, as applicable. The rate of acceleration is preset by the ACCEL potentiometer on the controller
control board.

STOP

If a RUN-STOP-JOG switch is used, place the switch in STOP position. Otherwise, initiate a Stop command.
A Stop command will stop the motor at a rate proportional to the stopping rate of the motor load.

If the controller has dynamic braking, the motor stopping time will be reduced. Dynamic braking provides
exponential rate braking of the motor armature, which occurs when the circuit is opened between the controller and
the motor armature, and one or more resistors connect across the motor armature.

The dynamic braking resistors provide initial braking torque as shown in Table 5.

BOOK0795-F

An antiplug feature is included with optional Armature Contactor Reversing With Dynamic Braking (Option

1004). This feature prevents restarting the motor before the motor has braked to a stop.

SPEED CONTROL

Motor speed is directly proportional to the setting of the MOTOR SPEED potentiometer or the magnitude of
an external speed reference signal, as applicable. This potentiometer or the speed reference signal may be adjusted
while the motor is running or may be preset before the motor is started.

The rates of acceleration and deceleration are preset by the ACCEL and DECEL potentiometers, respec­tively, located on the controller control board.

Maximum speed and minimum speed (or offset) are preset by the MAX SPD and MIN SPD potentiometers,
respectively, located on the control board.

JOG

If a RUN-STOP-JOG switch is used, place the switch in JOG position. Otherwise initiate a Jog command.
Jog is momentary, causing motor rotation only while the switch is held in JOG position or while a Jog command is
active. Release the switch to stop the motor.

Normally, jog speed is directly proportional to the setting of the MOTOR SPEED potentiometer. If a sepa­rate JOG SPEED potentiometer is used, jog speed will be directly proportional to the setting of the JOG SPEED
potentiometer.

REVERSE

To reverse motor rotation on controllers with reversing capabilities, initiate a Stop function and then initiate
a reversing command. The motor will then accelerate to the setting of the MOTOR SPEED potentiometer or exter­nal speed reference signal, as applicable. Forward and reverse speed ranges are identical.

If a FWD-REV switch is used, it must have a center position interlock, which requires a momentary relax­ation of pressure before the opposite position can be engaged. The center position causes a Stop command and
allows time for the motor to stop before a Reverse command is initiated. If a Reverse command is initiated while
the motor is rotating, motor and controller damage may occur.

If Option 1004 (Armature Contactor Reversing With Dynamic Braking) is installed, an antiplug feature pre­vents reversing the motor before the motor has stopped.

INOPERATIVE MOTOR

If the motor stops and/or won’t start, turn-off the AC supply to the controller, remove the controller cover (if
used), and check the AC line fuse on the controller control board. For the location of the fuse, see Figure 22 (page

43) or Figure 23 (page 44), as applicable. If the fuse is blown, refer to the Troubleshooting Table (Table 6).

18

BOOK0795-F

If the fuse is not blown, the internal overload monitor may have shut down the controller. The overload mon­itor will shut down the controller if the motor armature current exceeds 120% of rated for a length of time of con­tinuous operation. The length of time is determined by the amount of the overload. If the overload monitor trips,
reset the controller by initiating a Stop command, removing the overload, and then initiating a Run command to
restart. Repeated shutdown indicates an overload condition (mechanical or electrical) which must be removed.
Refer to the Troubleshooting Table (Table 6).

SECTION IV

MAINTENANCE AND REPAIR

GENERAL

1. Keep the controller dry and free of dust, dirt, and debris. No parts require periodic replacement.

2. Periodically turn-off the AC line supply to the controller and check all wire terminations to be sure they are
tight.

3. Visually check components for damage due to overheating or breakage. All damaged and/or faulty compo­nents must be replaced for satisfactory operation.

4. Maintain the motor according to maintenance instructions supplied by the motor manufacturer.

ADJUSTMENT INSTRUCTIONS

ACCELERATION

1. Set the MOTOR SPEED potentiometer at 100% or the external speed reference signal at maximum, as
applicable.

2. Initiate a Run command and observe the time required for the motor to reach maximum speed.

3. Adjust the ACCEL potentiometer for the desired rate. Full clockwise rotation is the fastest acceleration
(0.2 second), and full counterclockwise rotation is the slowest acceleration (30 seconds).

DECELERATION

1. With the motor running at maximum speed, quickly reset the MOTOR SPEED potentiometer to zero, or
quickly decrease the speed reference signal to minimum, as applicable, and observe the time required for
the motor to reach minimum speed.

2. Adjust the DECEL potentiometer for the desired rate. Full clockwise rotation is the fastest deceleration
(0.2 second), and full counterclockwise rotation is the slowest deceleration (30 seconds).

IR COMPENSATION

IR compensation is used only when the controller is programmed for armature feedback. The IR/TACH
potentiometer is factory set at zero (full counterclockwise rotation) for satisfactory operation with most motors. If
improved speed regulation is desired, readjust IR compensation as follows:

21

BOOK0795-F

1. Be sure Segments 2 and 3 of DIP Switch S3 are in ON (Closed) position.

2. If the motor is shunt-wound, run it at rated base speed. If the motor is a permanent-magnet type, run it

about 1/3 speed.

3. Turn the IR/TACH potentiometer clockwise slowly until motor speed becomes unstable. Then turn the

potentiometer counterclockwise until motor speed stabilizes.

MAXIMUM SPEED (ARMATURE FEEDBACK)

The MAX SPD potentiometer adjusts maximum speed by setting maximum armature voltage. The voltage
range is from 50% to 100% of rated armature voltage. If the controller is programmed for tachometer feedback, the
MAX SPD potentiometer sets the armature backup voltage.

1. Be sure Segments 2 and 3 of DIP Switch S3 are in ON (Closed) position.

2. Turn the MAX SPD potentiometer fully clockwise (100%). This setting provides 90 VDC armature volt­age with a 115 VAC line, or 180 VDC armature voltage with a 230 VAC line.

3. Run the motor at maximum speed, and turn the MAX SPD potentiometer counterclockwise for the desired
maximum speed.

NOTE: If the MAX SPD potentiometer is turned too far counterclockwise, speed instability may occur.

MAXIMUM SPEED (TACHOMETER FEEDBACK)

Tachometer feedback provides speed regulation characteristics as shown in Table 12, page 35. However, these
characteristics are based on the use of Fincor Electronics cataloged motors and generators. Regulation characteris­tics and drive performance cannot be guaranteed with motors and/or tachometer generators that have not been eval­uated. For example, some tachometer generators with low voltage/RPM ratios may not provide adequate feedback
signal levels at low speed.

1. Be sure Segments 2 and 3 of DIP Switch S3 are in OFF (Open) position.

2. Set Segment 1 of DIP Switch S3 for the expected tachometer generator speed at maximum speed, as fol­lows:

SEGMENT 1 POSITION TACH VOLTAGE

ON (Closed) 8V - 30V

OFF (Open) 31V - 175V

3. Turn the IR/TACH potentiometer fully counterclockwise (0%). This setting provides maximum motor
speed.

4. Be sure the MAX SPD potentiometer has been adjusted correctly.

22

BOOK0795-F

5. Run the motor at maximum speed, and start turning the IR/TACH potentiometer clockwise until motor

speed increases above desired speed. Continue turning the potentiometer clockwise until motor speed
decreases to desired speed.

MINIMUM SPEED

1. Be sure Segment 6 of DIP Switch S3 is in ON (Closed) position.

2. Turn the MIN SPD potentiometer fully counterclockwise (0%) for zero speed.

3. Set the MOTOR SPEED potentiometer at 0% or the external speed reference signal at minimum, as appli-

cable.

4. Initiate a Run command and adjust the MIN SPD potentiometer for the desired minimum speed (adjustable

from 0 to 40% of motor base speed).

OFFSET

An offset adjustment is desirable when a 4 mA to 20 mA speed reference signal is used. The MIN SPD

potentiometer compensates for the 4 mA offset.

1. Be sure Segment 6 of DIP Switch S3 is in OFF (Open) position, and a wire jumper connects between TB2-

1 and TB2-3.

2. Set the speed reference signal at 4 mA and initiate a Run command.

3. Adjust the MIN SPD potentiometer as desired.

NOTE: The MIN SPD potentiometer may be ineffective between 50% and 100%.

CURRENT LIMIT

1. Turn the CUR LMT potentiometer fully clockwise (100%) to limit motor armature current at 150% of

rated.

2. Turn the CUR LMT potentiometer counterclockwise to reduce maximum motor armature current.

NOTES: a. An LED glows red on the controller control board when motor armature current is being lim-

ited.

b. An external 5K ohm Current (Torque) Limit potentiometer can be used as shown in Figure 12

on page 12. Segment 5 of DIP Switch S3 must be in OFF (Open) position if an external Cur­rent (Torque) Limit potentiometer is desired.

SPECIFICATIONS

1. AC LINE PROTECTION - A 100,000 ampere interrupting capacity AC line fuse provides instantaneous

protection from peak loads and fault currents. This line fuse is located inside the controller. A molded­case, magnetic-trip circuit breaker (Option 1010) is available for Model 2601 Controllers, which provides
a manual disconnection to the controller, and also provides automatic instantaneous trip protection from a
peak load.

2. AUXILIARY CONTACT - A normally-open Form A relay contact, rated 5 ampere @115 VAC and 30
VDC, is available for external use. The relay energizes when a Run command is initiated, and de-energizes
when a Normal Stop command is initiated, the overload monitor trips, or the anti-restart circuit is acti­vated.

3. CONTROL VOLTAGE - A transformer coupled 24 VDC power supply isolates all magnetic control
logic and operator controls from the AC power source for operator protection.

4. DIP SWITCH SETTINGS - A 7-position DIP Switch (S3) is used to program the controller for various
applications as shown in Table 13.

BOOK0795-F

5. FEEDBACK - Two selectable modes of analog feedback are provided, as follows. See Table 12 (page 35)

for speed regulation characteristics.

a. Armature Feedback - Counter EMF voltage feedback with IR compensation, adjustable for individ-

ual motor characteristics.

b. DC Tachometer Feedback - The controller provides voltage scaling, and terminals for accepting the

output of a DC tachometer generator, mechanically coupled to the drive motor armature. The control­ler will automatically transfer to armature feedback if the tachometer signal is lost. Tachometer gener­ators with an output of 8 VDC to 175 VDC at maximum speed may be used.

6. FIELD SUPPLY - A half-wave or full-wave shunt field supply is available as shown in Table 14.

a. Low inductance motors require a full-wave field to prevent current instability.

7. ISOLATED REGULATOR - The internal DC circuits are isolated from the AC power source for opera-

tor and equipment safety, and for simplified application. The common of the input speed reference signal
may be grounded or connected without additional isolation to other drive controllers or grounded external
signal sources. This isolation eliminates line voltage to ground potentials on the motor speed potentiome­ter.

8. MOTOR CONTACTOR - Controller model numbers with an ‘A’ suffix, e.g., 2601A, 2611AP3, have a

DC magnetic armature contactor, which disconnects both motor armature leads from the controller. An
antiplug circuit ensures that the contactor does not make or break DC.

9. MOTOR OVERLOAD - A nonadjustable inverse time overload circuit continuously monitors motor

armature current and shuts down the controller whenever the current exceeds 120% of rated for a length of
time of continuous operation. The length of time is determined by the amount of overload.

10. POWER CONVERSION - The DC power bridge consists of four SCR’s and a freewheeling diode. Each

device is rated at least 600 PIV. The controller base forms an integral heat sink, with the power devices
electrically isolated from the base.

11. SELECTABLE CAPABILITIES - The DIP Switch (S3) allows the user to select various modes of oper-

ation, as follows:

37

BOOK0795-F

a. External DC Signal Follower - The controller will operate with an external 0 - 5 VDC, 0 - 10 VDC,

b. Line Starting - By placing S3-7 in OFF (Open) position, the ‘anti-restart’ feature will be disabled, and

c. Tachometer Feedback - To select tachometer feedback with armature feedback backup, place S3-2

or 4 - 20 mA speed reference signal. The signal may be grounded or not grounded, isolated or not iso­lated. Motor speed will be proportional to the signal.

0 - 5 VDC - Place S3-4 in OFF (Open) position, and connect the signal to TB2-6.

0 - 10 VDC - Place S3-4 and S3-6 in ON (Closed) position, and connect the signal to TB2-2.

4 - 20 mA - Place S3-4 in ON (Closed) position, and connect the signal to TB2-6 (+) and TB2-5 (-). To
use the MIN SPD potentiometer as a 4 mA offset adjustment, place S3-6 in OFF (Open) position, and
jumper TB2-1 to TB2-3.

the controller may be started and stopped with an external AC line contactor. In addition, a wire
jumper must be connected between TB2-8 and TB2-9. If full speed operation is desired, connect
another wire jumper between TB2-2 and TB2-3.

and S3-3 in OFF (Open) position, and connect the tachometer generator signal to TB2-7 (-) and TB2-5
(+). Select the tachometer generator voltage range with S3-1, as follows:

8 VDC - 30 VDC at maximum speed, place S3-1 in ON (Closed) position.

31 VDC - 175 VDC at maximum speed, place S3-1 in OFF (Open) position.

d. Torque Regulator - The controller will function as a torque regulator when S3-5 is set to OFF (Open)

position. This allows an external potentiometer to set maximum motor torque (0 - 150% of rated).

12. STATUS INDICATOR - A bicolor LED glows red when motor armature current is being limited by the
controller current limit, and glows green when armature current is not being limited.

13. VOLTAGE TRANSIENT PROTECTION - A metal oxide suppressor (varistor) across the AC line is
combined with RC snubbers across the power bridge to limit potentially damaging high voltage spikes
from the AC power source.
