Open-Type (Non-Flange) Enclosure
<1> The accuracy of these values depends on motor characteristics, ambient conditions, and drive settings. Specifications may vary with different motors
and with changing motor temperature. Contact Yaskawa for consultation.
<2> Disable Stall Prevention during deceleration (L3-04 = 0) when using a regenerative converter, a regenerative unit, a braking resistor or the Braking
Resistor Unit. The default setting for the Stall Prevention function will interfere with the braking resistor.
<3> 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.
<4> Actual specifications may vary depending on motor characteristics.
<5> Overload protection may be triggered when operating with 150% of the rated output current if the output frequency is less than 6 Hz.
<6> May be shorter due to load conditions and motor speed.
<7> Ground protection cannot be provided when the impedance of the ground fault path is too low, or when the drive is powered up while a ground
fault is present at the output.
