of filters that meet the Industrial or Residential Standard. Additional shielded cable and/or AC Line cables may be required along with a signal
isolator.
3 –IMPORTANT APPLICATION INFORMATION
3.1 –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.
CAUTION! 1. Some motors have low speed characteristics which cause overheating and winding failure under light load or no-load
conditions. If themotor is operated in this mannerfor an extended period of time, it is recommended that the unloadedmotor current be checked
from 2 –15 Hz (60 –450 RPM) to ensuremotor current does not exceed the nameplate rating. Do not use themotor if the motor current exceeds
the nameplate rating. 2. It is recommended that the drive be used with Inverter Duty or TENV motors. Inverter duty and most totally enclosed
non-ventilated (TENV) motors can provide full rated torque over an extended speed range without overheating. See Figure 2. 3. 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 3.

3.2 –Electronic Motor Overload Protection
The drive contains Modified I2t 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 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 and breakdown torque.
Standard I2t 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, which includes I2t plus an I•t timing circuit (as described in the paragraph below), 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.
