7 IMPORTANT APPLICATION INFORMATION
7.1 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.
Note: Some fan-cooled motors can be used over a wider speed range. Consult the
motor manufacturer 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 3.
It is recommended that the
drive be used with Inverter
Duty or TENV motors.
WARNING! Some motors have low speed characteristics, which cause
overheating and winding failure under light load or no load conditions. If the motor is
operated in this manner for an extended period of time, it is recommended that the
unloaded motor current be checked from 2 – 15 Hz (60 – 450 RPM) to ensure motor
current does not exceed the nameplate rating. If the motor current exceeds the
nameplate rating, the Boost Value may have to be decreased (see Function 3.16).
Do not use motor if the motor current exceeds the nameplate rating.
If external cooling is provided,
open ventilated motors can also
achieve an extended speed range
at full rated torque. A 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 4.

FIGURE 3
MAXIMUM ALLOWED
FIGURE 4
13
7.2 ELECTRONIC MOTOR OVERLOAD PROTECTION
The drive contains Modified I
2
t Overload Protection (UL approved as an overload
protector for motors). Part of this function consists of a Current Limit (CL) circuit,
which limits the drive current to a preset level of 160% of the Motor Nameplate Rated
Current setting. The factory setting for Motor Nameplate Current (Function 0.01)
is the drive rated current, as shown in Table 2 on page 9, which must be set to
the actual motor nameplate current (see Important Programming Information
(Section 6 on page 12).
Standard I
2
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. KB's
RMS Current Limit Circuit avoids this nuisance tripping while providing maximum
motor protection.
If the motor is overloaded to 120% of the Motor Nameplate Rated Current, the I
2
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.
8 MOUNTING
Use the supplied mounting template to facilitate locating the holes to mount the drive.
It is recommended that the drive be mounted vertically on a flat surface with adequate
ventilation. Leave enough room below the drive to allow for AC Line, motor
connections, and any other connections that are required. Care should be taken to
avoid extreme hazardous locations where physical damage can occur. When
mounting the drive in an enclosure, the enclosure should be large enough to allow
proper heat dissipation so that the ambient temperature does not exceed 40 °C
(104 °F) at full rating. See Figure 5 on page 15.
WARNING! DO NOT USE THIS DRIVE IN AN EXPLOSIVE
ENVIRONMENT. AN EXPLOSION CAN CAUSE SERIOUS OR FATAL INJURY.
THIS DRIVE IS NOT EXPLOSION PROOF.

12.1 AC LINE INPUT AND GROUND
Connect the 1-phase AC line input to TB1 Terminals "L1" and "L2". Connect the
Ground (earth) to TB1 Terminal "GND". See Figure 8 on page 19.
Note: The actual AC Line Input voltage must correspond to the setting of Jumper J3.
For 208/230 Volt AC Line Input, be sure that Jumper J3 is not installed. For 115 Volt
AC Line input, install Jumper J3 (supplied). Applying 230 Volts to the drive set for 115
Volt AC Line input will cause catastrophic failure. See Section 10 on page 18.
12.2 MOTOR AND GROUND
Connect the Motor to TB1 Terminals "U", "V", and "W". Connect the Ground (earth) to
TB1 Terminal "GND". See Figure 8 on page 19. Motor cable length should not exceed
100 feet (30 m) – special reactors may be required – consult our Sales Department.
Be sure that the Current Limit is calibrated to the actual motor nameplate current
rating. Do not exceed the drive's maximum current rating. See Function 0.01.
Note: If the motor does not rotate in the desired direction, either: 1. Reverse any two
motor leads (with the AC Line disconnected and the motor stopped). 2. Use the
FWD/REV Key. Also see Appendix B on page 37 to change the operating sense of
the FWD/REV Key. 3. Use Function 1.01 to reprogram forward and reverse direction.
12.3 AC LINE INPUT FUSING
The drive does not contain AC Line fuses. For the recommended fuse or circuit
breaker rating, see Table 2 on page 9. Do not fuse motor leads. Most electrical codes
require that each ungrounded conductor contain circuit protection. Do not fuse neutral
or ground connections. It is recommended to install a fuse (Littelfuse 326, Buss ABC,
or equivalent) or a circuit breaker (Square D QOU or equivalent) in series with each
ungrounded conductor.
13 HIGH VOLTAGE DIELECTRIC WITHSTAND TEST (HI-POT TEST)
The drive has passed factory hi-pot testing in accordance with UL requirements.
Testing agencies such as UL, CSA, etc., usually require that equipment undergo an
AC Hi-Pot Test. In order to prevent catastrophic damage to the drive, which has been
installed in the equipment, the following procedure is recommended. A typical Hi-Pot
Test Setup is shown in Figure 9 on page 21.

Hi-Pot Test Voltage = (Line Voltage X 2) + 1000
EQUIPMENT
A ramp-up type AC Hi-Pot Tester must be used. A suggested Hi-Pot Tester is
Slaughter Model 2550, or equivalent.
PROCEDURE
Warning! All equipment AC line inputs must be disconnected from the AC
power before performing the Hi-Pot Test.
Note: If the Hi-Pot Tester does not have automatic ramping, then the hi-pot output
must be manually increased to the test voltage and then manually reduced to zero.
1. Set the Hi-pot Tester to the appropriate voltage, as shown in Table 5 above.
2. Connect all equipment AC power input lines together and connect them to the H.V.
lead of the Hi-Pot Tester.
3. Connect the RETURN of the Hi-Pot Tester to the frame on which the drive and
other auxiliary equipment are mounted. The Hi-Pot Tester must have an automatic
ramp-up to the test voltage and an automatic ramp-down to zero voltage.
CAUTION! Instantly applying the hi-pot voltage will cause irreversible damage to
the drive, which will void the warranty.

14 DRIVE OPERATION
Before operating the drive, read Section 14.2 for a description of the Keypad. See
Figure 1 on page 6, for the keypad layout. The 4-digit display can indicate various
functions of the drive: Set Frequency, Motor RPM, Output Current and Voltage,
Custom Units, Function Numbers, Function Codes or Values, and Fault Codes. See
Section 15 on pages 29 and 30.
See Section 16 on pages 31 – 35, for programming information. If an error message
appears while programming the drive, see Table 6 on page 30.
WARNING! The STOP Key is never to be used as an Emergency Stop
or safety disconnect since it is not fail-safe. Use only the AC Line for this
purpose.
14.1 START-UP PROCEDURE
After the drive has been properly setup (Jumper J3 set to the corresponding AC Line
input voltage being applied to the drive) and wiring completed, the startup procedure
can begin. Set the On/Off AC Line Switch to the on position. If the AC power has been
properly brought to the drive, the On/Off AC Line Switch will illuminate. To start the
drive, press the RUN Key. The motor will begin to accelerate to the Set Frequency.
The factory Set Frequency is 05.00 Hz.
Note: If the motor does not rotate in the desired direction, either: 1. Reverse any two
motor leads (with the AC Line disconnected and the motor stopped). 2. Use the
FWD/REV Key. Also see Appendix B on page 37 to change the operating sense of
the FWD/REV Key. 3. Use Function 1.01 to reprogram forward and reverse direction.
14.2 KEYPAD DESCRIPTION
The Keypad has eight (8) keys, which are used to program drive functions. The
eight (8) LEDs provide indication of the drive’s operational status. The built-in
potentiometer is used to set the Drive Frequency (Function 2.00 set to "0001").
Note: To avoid damage, never operate the keypad with a screwdriver or other sharpended tool.
Application Notes: 1. Adjustment of Set Frequency can be switched between the
built-in potentiometer and the keypad using shortcut keys. See Appendix A on page
36. 2. For applications that require changing motor direction, the sense of the
FWD/REV Key can be changed, without requiring reprogramming the drive or
reversing any two motor leads. See Appendix B on page 37. 3. See Appendix C on

Note: This automatically sets Function 0.00 (Rated Motor Frequency) to "0000"
(60 Hz). For 50 Hz motors, set Function 0.00 to "0001".
OEM CUSTOM PROGRAM
Contains a custom program that is factory installed for a specific OEM application. Set
Function 5.06 to "1010" to activate this program.
Note: Unless the drive has been specifically programmed for a custom OEM
application, the default program is the same as the original factory program.
USER CUSTOM PROGRAM
When program changes are made by the user, these changes are stored in the Active
Memory location. These changes do not have to be stored and will remain in the
Active Memory unless additional changes are made. The user can store the First Set
of Changes prior to making the Second Set of Changes by setting Function 5.06 to
"1100". See example below in Table 7.
Typically, this feature would be used if the drive has been programmed for a particular
application and the user has another application for which some of the parameters
need to be changed but desires to retain the original settings.
