Specifications may vary with different motorsand 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 BrakingResistor 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 speeddown 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> A separate Momentary Power Loss Ride-Thru Unit is required for models 2A0004 to 2A0056 and 4A0002 to 4A0031 if the application needs tocontinue running for up to 2 seconds during a momentary power loss.<8> 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 groundfault is present at the output.<9> Models 4A0930 and 4A1200 are rated at 5.9 m/s2.<10> Removing the top protective cover or bottom conduit bracket from an IP20/NEMA Type 1 enclosure drive voids NEMA Type 1 protection whilemaintaining IP20 conformity.
