A.4 Drive Specifications 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. 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. Overload protection may be triggered when operating with 150% of the rated output current if the output frequency is less than 6 Hz.
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. 166 SIEP C710606 33A OYMC AC Drive – J1000 User Manual Item Specification Cooling Method JZAB0P1 to B0P7: self-cooled JZAB1P5: cooling fan JZA20P1 to 20P4: self-cooled JZA20P7 to 24P0: cooling fan JZA40P2 to 40P7: self-cooled JZA41P5 to 44P0: cooling fan
