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 rat-
ing, 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. 0.01 to enter the
motor nameplate current. See Figure 17, on page 24.
a. Model KBDA-27D – Has a maximum current rating of 6.7 Amps (2 HP (1.5 kW)) when used with a
208 – 230 Volt 50/60 Hz AC line input (factory setting of motor current and AC line input voltage).
When used with 115 Volt 50/60 Hz AC line input (Jumper J1 installed in the “115V” position), the
maximum rating of the drive is 5.5 Amps (1

⁄
2
HP (1.13 kW)). Be sure to reprogram Motor Current
(Function No. 0.01) to the actual motor nameplate current rating (not to exceed 5.5 Amps).
b. Model KBDA-29 – Has a maximum rating of 9.0 Amps (3 HP (2.25 kW)) when used with a 208 – 230
Volt 50/60 Hz 3-phase AC line input. When used with a 208 – 230 Volt 50/60 Hz single-phase AC
line input, the maximum rating of the drive is 6.7 Amps (2 HP (1.5 kW)). Be sure to reprogram Motor
Current (Function No. 0.01) to the actual motor nameplate current rating (not to exceed 6.7 Amps).
