Cooling Method
<1> Instantaneous average deceleration torque refers to the torque required to decelerate the motor (uncoupled from the load) from the rated motor speed
down to zero in the shortest time.
<2> Ensure that Stall Prevention Selection during Deceleration is disabled (L3-04 = 0) or set to 3 when using a braking resistor or the Braking Resistor
Unit. The default setting for the stall prevention function will interfere with the braking resistor.
<3> Overload protection may be triggered when operating with 150% of the rated output current if the output frequency is less than 6 Hz.
<4> Ground protection cannot be provided under the following circumstances when a ground fault is likely in the motor windings during run: Low
ground resistance for the motor cable and terminal block; low ground resistance for the motor cable and terminal block; or the drive is powered up
from a ground short.
<5> All models have an IP20/Open-Chassis enclosure as standard. Use the NEMA Type 1 Kit option to convert drives to an IP20/NEMA Type 1
enclosure rating.
