Warning

Do not install, remove, or rewire this equipment with power applied. Failure to heed this warning may result in fire, explosion, or serious injury.

Circuit potentials are at 115 or 230 VAC above ground. To prevent the risk of injury or fatality, avoid direct contact with the printed circuit board or with circuit elements.

Do not disconnect any of the motor leads from the drive unless power is removed and the drive is disabled. Opening any one motor lead may destroy the drive.





Wiring

• Use 18 AWG wire for speed adjust potentiometer wiring. Use 16

AWG wire for field (F1, F2) wiring. Use 14 AWG wire for AC line

(L1, L2) and motor (A1, A2) wiring.

Page 13

7Installation

Shielding guidelines

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 logic leads

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.

Warning

Under no circumstances should power and logic leads be bundled together. Induced voltage can cause unpredictable behavior in any electronic device, including motor controls.

Fusing

The XL3300A has three 25A, fast-acting fuses installed (FU501 -

FU503). FU501 connects with the L1 terminal (the hot leg of the

AC line voltage). FU502 connects with the 230 terminal. FU503

connects with the A2 terminal to protect the motor from related

conditions not protected by the AC line fuses. If the horsepower

rating of the motor is less than the maximum horsepower rating of

the drive, replace the fuse with a lower rated one. Rate fuses at

150% times the maximum armature current.

Page 19

Voltage Follower

Instead of using a speed adjust potentiometer, the drive may be

wired to follow an analog input voltage that is isolated from earth

ground. Connect the signal input (+) to S2 and the signal common

(-) to S1 (Figure 7). Make no connection to S3. A potentiometer

can be used to scale the analog input voltage if needed. To

achieve greater linearity and control, use an interface device such

as a Minarik model PCM4 to scale the analog input voltage.

Before applying power

Operation

• Verify that no conductive material is present on the printed circuit

board.

• Set both voltage selection switches (SW501 and SW502) to

either 115 or 230 to match the AC line voltage being used. See

Figure 8 (page 16).

Warning

Change voltage selection switch settings only when the drive is disconnected from the AC line voltage. Make sure both switches are set to their correct position. If the switches are improperly set to a lower voltage position, the motor will not run at full voltage. If the switches are improperly set to a higher voltage position, the motor will overspeed, which may cause motor damage.

Operation

Startup

1. Turn the speed adjust potentiometer full counterclockwise

(CCW).

2. Apply AC line voltage.

3. Slowly advance the speed adjust potentiometer clockwise (CW).

The motor slowly accelerates as the potentiometer is turned

CW. 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

on page 40 for further assistance.

Diagnostic LEDs

XL3300A drives are equipped with the following diagnostic LEDs:

• The green POWER ON LED turns on when power is applied to

the drive and turns off when power is removed.

• The red CURR LIMIT LED turns on when the drive reaches

current limit and turns off when the drive is not in current limit

(normal operation).

Page 23

17Operation

Starting and Stopping Methods

Line starting and line stopping

Line starting and line stopping (applying and removing AC line

voltage) is recommended for infrequent starting and stopping of a

drive only. When AC line voltage is applied to the drive, the motor

accelerates to the speed set by the speed adjust potentiometer.

When AC line voltage is removed, the motor coasts to a stop.

Inhibit circuit

The XL3300A has an inhibit circuit that causes the motor to coast

to zero speed when the inhibit pins are shorted together.

Removing the connection between the inhibit pins allows the motor

to accelerate to the speed set by the speed adjust potentiometer

(see Figure 9, page 19).

Warning

The inhibit circuit is used for frequent starts and stops. It must never be used as an emergency stop. It may not stop a drive that is malfunctioning. Removing AC line power (both L1 and L2) is the only acceptable method for emergency stopping.



Page 24

Operation

Minarik Corporation offers two accessory plug harnesses for

connecting to the inhibit pins: part number 201-0024 [inhibit plug

with 18 in. (46 cm) leads]; and part number 201-0079 [inhibit plug

with 36 in. (91 cm) leads]. Twist these leads and separate them

from other power-carrying wires or sources of electrical noise. Use

shielded cable if the inhibit leads are longer than 18 in. (46 cm). If

shielded cable is used, ground only one end of the shield to earth

ground. Do not ground both ends of the shield.

Decelerating to minimum speed

The circuit shown in Figure 10 may be used to decelerate a motor

to a minimum speed. Closing the switch between S1 and S2

decelerates the motor from set speed to a minimum speed

determined by the MIN SPD trimpot setting. If the MIN SPD

trimpot is set full CCW, the motor decelerates to zero speed when

the switch between S1 and S2 is closed. The DECEL trimpot

setting determines the rate at which the drive decelerates. By

opening the switch, the motor accelerates to set speed at a rate

determined by the ACCEL trimpot setting.

Each drive is factory calibrated to its maximum horsepower rating.

Readjust the calibration trimpot settings to accommodate lower

current rated motors.

All adjustments increase with CW rotation, and decrease with CCW

rotation. Use a non-metallic screwdriver for calibration. Each

trimpot is identified on the printed circuit board. See Figure 12

(page 24) for trimmpot locations.

Calibration

Warning

Dangerous voltages exist on the drive when it is powered. 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.

Minimum Speed (MIN SPD)

The MIN SPD setting determines the motor speed when the speed

adjust potentiometer is turned full CCW. It is factory set for

minimum rated speed.

To calibrate, set the MIN SPD trimpot full CCW. Turn the speed

adjust potentiometer full CCW. Adjust the MIN SPD trimpot until the

desired minimum motor speed is reached.

Maximum Speed (MAX SPD)

The MAX SPD setting determines the motor speed when the speed

adjust potentiometer is turned full CW. It is factory set for maximum

rated speed.

To calibrate, set the MAX SPD trimpot full CCW. Turn the speed

adjust potentiometer full CW. Adjust the MAX SPD trimpot until the

desired maximum motor speed is reached.

Page 31

Torque Limit (TORQ LIMIT)

The TORQ. LIMIT setting determines the maximum armature current

output of the drive. It is factory set at 120% of rated motor current.

Recalibrate the TORQ. LIMIT setting when using a lower horsepower

motor. Refer to Figure 13 (page 30) for approximate TORQ. LIMIT

settings, or recalibrate using the following procedure:

1. With the power disconnected from the control, connect a DC

ammeter (0 - 15 minimum scale) in series with the armature.

2. Set the TORQ. LIMIT trimpot to minimum (full CCW).

3. Set the speed adjust potentiometer to maximum speed

(full CW).

4. Carefully lock the motor armature. Be sure that the motor is firmly

mounted.

5. Apply line power. The motor should be stopped.

6. Slowly adjust the TORQ. LIMIT trimpot CW until the armature

current is 120% of motor rated armature current.

7. Turn the speed adjust potentiometer CCW until the motor stops.

8. Remove the line power.

9. Remove the stall from the motor.

10. Remove the ammeter in series with the motor armature if it is no

longer needed.

Warning

TORQ. LIMIT should be set to 120% of motor nameplate current rating. Continuous operation beyond this rating may damage the motor. If you intend to operate beyond the rating, contact your Minarik representative for assistance.

Acceleration (ACCEL)

The ACCEL setting determines the time the motor takes to ramp to

a higher speed. See Specifications on page 1 for approximate

acceleration times. ACCEL is factory set to its minimum value (full

CCW).

Use the following procedure to set the acceleration time:

1. Set the speed adjust potentiometer full CCW. The motor should

run at minimum speed (as set by the MIN SPD trimpot, page

25).

2. Turn the speed adjust potentiometer full CW 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.

Page 33

Deceleration (DECEL)

The DECEL setting determines the time the motor takes to ramp to

a lower speed. See Specifications on page 1 for approximate

deceleration times. DECEL is factory set for the fastest

deceleration time (full CCW).

Use the following procedure to set the deceleration time:

1. Set the speed adjust potentiometer full CW. The motor should

run at maximum speed (as set by MAX SPD trimpot, page 25).

2. Turn the speed adjust potentiometer full CCW 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.

IR Compensation (IR COMP)

The IR COMP trimpot setting determines the degree to which

motor speed is held constant as the motor load changes. It is

factory set for optimum motor regulation.

Recalibrate the IR COMP setting when using a lower current rated

motor. Refer to Figure 13 (page 30) for approximate IR COMP

settings, or use the following procedure to recalibrate the IR

COMP:

1. Set the IR COMP trimpot to minimum (full CCW).

2. Rotate the speed adjust potentiometer until the motor runs at

midspeed without load (for example, 900 RPM for an 1800 RPM

motor). A hand held tachometer may be used to measure

motor speed.

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. If

the motor oscillates (overcompensation), the IR COMP trimpot

may be set too high (CW). Turn the IR COMP trimpot CCW to

stabilize the motor.

5. Unload the motor.

JOG

The JOG setting determines the motor speed when the drive is set

to the JOG mode. To control the speed with the JOG trimpot:

1. Connect the SPD IN and JOG terminals.

2. Calibrate the JOG trimpot until the motor runs at the desired

JOG speed.

Calibration with low voltage DC motors

Using XL3300A with a low voltage DC motor requires using a lower

resistance speed adjust potentiometer, and recalibrating the MAX

SPD trimpot settings. See Figure 14 for MAX SPD trimpot settings.

NOTE: MAX SPD trimmer pot settings are approximate. Verify

maximum armature voltage with a voltmeter. Care should be taken

when using low voltage motors to ensure motor insulation rating is

above bus voltage of the drive.

Application Notes

Leader-Follower Application

In this application, use a PCM4 to monitor the speed of the leader

motor (Figure 18). The PCM4 isolates the leader motor from the

follower drive, and outputs a voltage proportional to the leader

motor armature voltage. The follower drive uses this voltage

reference to set the speed of the follower motor. An optional ratio

potentiometer may be used to scale the PCM4 output voltage.

Single Speed Potentiometer Control of Multiple Drives

Multiple drives can be controlled with a single speed adjust

potentiometer using a PCM4 at the input of each drive to provide

isolation (Figure 19). Optional ratio potentiometers can be used to

scale the PCM4 output voltage, allowing independent control of

each drive.

Reversing

A dynamic brake may be used when reversing the motor direction

(Figure 20). Use a three-pole, three-position switch rated for at

least the maximum DC armature voltage and maximum braking

current. Wait for the motor to stop completely before switching it to

either the forward or reverse direction. See page 22 for

recommended dynamic brake resistor sizes.

Reversing with a DLC600 Controller

A DLC600 controller can be used in a reversing application. The

DLC600 must be inhibited while braking. Without the inhibit feature,

the DLC600 will continue to regulate. This will cause overshoot

when the DLC600 is switched back to the drive. Figure 21 shows

the connection of the reversing circuit to an XL3300A series drive

and a DLC600. NOTE: Only one DLC option (Optical Encoder or

Magnetic Pickup) may be used at a time.
