IMPORTANT APPLICATION INFORMATION 1. 50 Hz Motors – This drive has been factory programmed to operate 60 Hz motors. For 50 Hz motor operation, set Function No. 0.00 to “0001”. See Figure 16, on page 23. 2. Motor Current Setting – The motor current for all drive models is factory set to the maximum drive rating, as shown in Table 3, on page 10. In order for the motor overload protection to operate properly, the drive must be reprogrammed to the actual motor nameplate current. Use Function No. 0.
1.1 AC LINE INPUT CONNECTION – Connect the AC line input to Terminal Block TB1. See Section 6.1, on page 18. Application Note – If operation with a Ground-Fault Circuit-Interrupter (GFCI) is required, see Function No. 0.04, on page 32. Note: The rated AC line voltage of the drive must match the actual AC line input voltage. On Models KBDA-24D, 27D, the setting of Jumper J1 must match the AC line input voltage. Model KBDA-24D – Terminals “L1”, “L2” – Designed for single-phase AC line input only.
2 SAFETY WARNING Definition of Safety Warning Symbols Electrical Hazard Warning Symbol – Failure to observe this warning could result in electrical shock or electrocution. Operational Hazard Warning Symbol – Failure to observe this warning could result in serious injury or death. This product should be installed and serviced by a qualified technician, electrician, or electrical maintenance person familiar with its operation and the hazards involved.
3 INTRODUCTION Thank you for purchasing the KBDA Adjustable Frequency Drive. KB Electronics, Inc. is committed to providing total customer satisfaction by producing quality products that are easy to install and operate. The KBDA Adjustable Frequency Drives are variable speed controls housed in a rugged NEMA-4X / IP-65 washdown and watertight die-cast aluminum enclosure. They are designed to operate 208 – 230 and 400/460 Volt 50 & 60 Hz 3-phase AC induction motors from subfractional thru 5 HP.
• LED Status Indicators – The LEDs provide indication of the drive’s status and operating mode (Hz, PGM, LCL/REM, STOP, FWD, REV, OL, JOG/REM). • Multi-Function Output Relay Contacts – Can be used to turn on or off equipment or to signal a warning if the drive is put into various modes of operation. (The optional IODA Input/Output Multi-Function Board contains 9 digital and analog inputs, 4 digital and analog outputs, and 2 additional relay outputs.

4 IMPORTANT APPLICATION INFORMATION 4.1 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. FIGURE 8 – MAXIMUM ALLOWED MOTOR TORQUE VS.
If the motor is overloaded to 120% of the Motor Nameplate Rated Current setting, the I2t 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. *UL approved as an overload protector for motors. 5 MOUNTING INSTRUCTIONS It is recommended that the drive be mounted vertically on a flat surface with adequate ventilation.

When the Multi-Function Output Relay is programmed to function as a “Fault” relay (Function No. 5.00 set to “0001”) and a fault occurs while the drive is in the Run Mode, the relay contacts will change state. The Normally Open (N.O.) contact (closed in the Run Mode) will open and the Normally Closed (N.C.) contact (open in the Run Mode) will close. See Table 5, on page 19.
8.2 The hi-pot tester must have an automatic ramp-up to the test voltage and an automatic rampdown to zero voltage. 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. This procedure must be followed for each machine to be tested. A suggested hi-pot tester is Slaughter Model 2550.
operational status, as described in Section 11, on page 41. A Main Speed Potentiometer is also provided to set the Drive Frequency (Function No. 2.00 set to “0001”). See Figure 2, on page 10. Note: To avoid damage, never operate the keypad with a screwdriver or other sharp-ended tool. TABLE 6 – KEYPAD DESCRIPTION Key Description Starts or Stops the drive Changes motor direction.
