Cooling Method
CIMR-JoBA0001 to 0006: self-cooled
CIMR-JoBA0010: cooling fan
CIMR-Jo2A0001 to 0004: self-cooled

CIMR-Jo4A0005 to 0011: cooling fan
<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.
