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> NEMA Type 1 kit is sold separately.
