5 IMPORTANT APPLICATION INFORMATION

WARNING! Do not use this drive in an explosion-proof application.

5.1 MOTOR WITH EXTERNAL FAN COOLING: Most totally enclosed fan-cooled (TEFC) and

open ventilated 3-phase AC induction motors will overheat if used beyond a limited speed range at full torque. Therefore, it is necessary to reduce motor load as speed is decreased.

CAUTION!

2. It Is Recommended that the Drive be used with Inverter Duty or TENV Motors.

Note: Some fan-cooled motors can be used over a wider speed range. Consult your Baldor District Office for details.

Inverter duty and most totally enclosed non-ventilated (TENV) motors can provide full rated torque over an extended speed range without overheating. See Figure 7 on page 18.

If external fan cooling is provided, open ventilated motors can also achieve an extended speed range at full rated torque. A box fan or blower with a minimum of 100 CFM per HP is recommended. Mount the fan or blower so the motor is surrounded by the airflow. See Figure 8.

5.2 ELECTRONIC MOTOR

OVERLOAD PROTECTION:

The drive contains Modified I

Overload Protection.* Part of this function consists of a Current Limit (CL) circuit, which limits the drive current to a factory preset level of 160% of the rated drive current. The CL Trimpot is used to recalibrate the drive current from 60% thru 200%. The Power Start™ circuit provides an overshoot function that allows most motors to develop more than 200% of starting torque.

Standard I

t is undesirable because it causes nuisance tripping. It allows a very high motor current to develop and will turn the drive off after a short period of time. The RMS Current Limit Circuit avoids this nuisance tripping while providing maximum motor protection.

If the motor is overloaded to 120% of full load (75% of the CL setting), the I

t Timer starts. If the motor continues to be overloaded at the 120% level, the timer will shut down the drive after 30 minutes. If the motor is overloaded to 160% of full load, the drive will trip in 6 seconds. See Section 7.6, on page 23.

*UL approved as an overload protector for motors.

7 TRIMPOT ADJUSTMENTS

The drive contains trimpots that are factory set for most applications. See Figure 3, on page 12, for the location of the trimpots and their approximate factory calibrated positions. Some applications may require readjustment of the trimpots in order to set the drive for a specific requirement. The trimpots may be readjusted as described.

WARNING! IF POSSIBLE, DO NOT ADJUST TRIMPOTS WITH THE MAIN POWER APPLIED. IF ADJUSTMENTS ARE MADE WITH THE MAIN POWER APPLIED, AN INSULATED ADJUSTMENT TOOL MUST BE USED AND SAFETY GLASSES MUST BE WORN. HIGH VOLTAGE EXISTS IN THIS DRIVE. FIRE AND/OR ELECTROCUTION CAN RESULT IF CAUTION IS NOT EXERCISED. “ALL” SAFETY WARNINGS ON, PAGE 8, MUST BE READ AND UNDERSTOOD BEFORE PROCEEDING.

7.1 MINIMUM SPEED (MIN): Sets the minimum

speed of the motor. The MIN Trimpot is factory set to 0% of frequency setting. For a higher minimum speed, setting, rotate the MIN Trimpot clockwise. See Figure 16.

7.2 MAXIMUM SPEED (MAX): Sets the maximum

speed of the motor. The MAX Trimpot is factory set for 100% of frequency setting. For a lower maximum speed setting, rotate the MAX Trimpot, counterclockwise. For a higher maximum speed setting, rotate the MAX Trimpot clockwise. See Figure 17.

7.3 ACCELERATION (ACCEL): Sets the amount of

time for the motor to accelerate from zero speed to full speed. The ACCEL Trimpot is factory set to

1.5 seconds. For a longer acceleration time, rotate the ACCEL Trimpot clockwise. For more rapid acceleration, rotate the ACCEL Trimpot counterclockwise. See Figure 18.

Note: Rapid acceleration settings may cause the current limit circuit to activate, which will extend the acceleration time.

7.4 DECELERATION (DECEL): Sets the amount of

time for the motor to decelerate from full speed to zero speed. The DECEL Trimpot is factory set to

1.5 seconds. For longer deceleration time, rotate the DECEL Trimpot clockwise. For more rapid deceleration, rotate the DECEL Trimpot counterclockwise. See Figure 19.

Application Note: On applications with high

inertial loads, the deceleration may automatically increase in time. This will slow down the rate of speed of decrease to prevent the bus voltage from rising to the Overvoltage Trip point. This function is called Regeneration Protection. It is recommended that for very high inertial loads that both the ACCEL and DECEL Trimpots be set to greater than 10 seconds.

7.5 SLIP COMPENSATION (COMP): Sets the amount

of Volts/Hz to maintain set motor speed under varying loads. The COMP Trimpot is factory set to

1.5 Volts/Hz, which provides excellent speed regulation for most motors. To increase the slip compensation, rotate the COMP Trimpot clockwise. To decrease the slip compensation, rotate the COMP Trimpot counterclockwise. See Figure 20.

Page 23

FIGURE 21 – CURRENT

LIMIT TRIMPOT RANGE

FIGURE 22 – I

T TRIP TIME vs.

MOTOR CURRENT

The slip compensation may be adjusted as follows:

A. Connect an AC RMS ammeter in series with one motor phase.

B. Run the motor and set the unloaded speed to

approximately 50% (900 RPM on 4-pole 1500/1725 RPM motors).

C. Using a tachometer, record the unloaded speed.

D. Increase motor loading until motor current is equal to the nameplate rated current (AC Amps).

E. Adjust the COMP Trimpot until the loaded RPM is equal to the unloaded RPM.

The motor is now compensated to provide constant speed under varying loads.

7.6 MOTOR OVERLOAD (I

t) WITH RMS

CURRENT LIMIT (CL)*: Sets the current limit

(overload), which limits the maximum current to the motor, preventing motor burnout and eliminating nuisance trips. The CL Trimpot is factory set to 160% of the drive rated current. To increase the current limit, rotate the CL Trimpot clockwise. To decrease the current limit, rotate the CL Trimpot counterclockwise. See Figure

21.

Figure 22, shows the I

t Trip Time vs. Motor Current. Also see Section 5.2, on page 17.

*UL approved as an electronic overload protector for motors.

CAUTION!

If the current limit is adjusted above 160% of the motor nameplate rating,

this can cause overheating of the motor.

CAUTION!

Do not leave

the motor in a locked rotor condition for more than a few seconds since damage may occur.

Notes: 1. In order to

ensure that the motor is properly protected with the I

t feature, it is required that the CL Trimpot be set for 160% of the motor nameplate rated current, as described above. 2. This adjustment must be made within 6 seconds or the I

t Trip will occur.

Page 24

The current limit may be adjusted as follows:

A. Connect an AC RMS ammeter in series with one motor phase.

B. Set the CL Trimpot fully counterclockwise.

C. Adjust the speed setting to 30%.

D. Lock the motor shaft and adjust the CL Trimpot to 160% of the motor nameplate

rated current.

8 DRIVE OPERATION

8.1 START-UP PROCEDURE: After the drive has been properly setup (jumpers and

trimpots set to the desired positions) and wiring completed, the start-up procedure can begin.

To start the drive, set the On/Off AC Line Switch to the “ON” position. If the AC power has been properly brought to the drive, the Pilot Light will illuminate.

LIMITED WARRANTY

For a period of 2 years from the date of original purchase, Baldor will repair or replace without charge, controls which our examination proves to be defective in material or workmanship. This warranty is valid if the unit has not been tampered with by unauthorized persons, misused, abused, or improperly installed and has been used in accordance with the instructions and/or ratings supplied. The warranty is in lieu of any other warranty or guarantee, expressed or implied. Baldor shall not be held responsible for any expense, including installation and removal, inconvenience, or consequential damage, including injury to any person, caused by items of our manufacture or sale. (Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above exclusion may not apply.) In any event, Baldor’s total liability, under all circumstances, shall not exceed the full purchase price of the control. Claims for purchase price refunds, repairs, or replacements must be referred to Baldor with all pertinent data as to the defect, the date purchased, the task performed by the control, and the problem encountered. No liability is assumed for expendable items, such as fuses.

Goods may be returned only with written notification including a Baldor Return Authorization Number and any return shipments must be prepaid.
