<1> Select control modes in accordance with drive capacity.
<2> High-frequency current superposition (n8-57=1) is available.
<3> Perform Rotational Auto Tuning.
<4> Contact Yaskawa or your nearest sales representative if using a PM motor other than Super Energy-saving Motors manufactured by Yaskawa Motor
Co., Ltd. (SSR1 series and SST4 series with standard specifications).
<5> 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.
<6> 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.
<7> 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.
<8> Actual specifications may vary depending on motor characteristics.
<9> Overload protection may be triggered when operating with 150% of the rated output current if the output frequency is less than 6 Hz.
<10> May be shorter due to load conditions and motor speed.
<11> A separate Momentary Power Loss Ride-Thru Unit is required for models 2A0004 to 2A0056 and 4A0002 to 4A0031 if the application needs to
continue running for up to 2 seconds during a momentary power loss.
<12> Ground protection is triggered when a ground short circuit occurs while the drive is running. The 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.

<14> Removing the top protective cover or bottom conduit bracket from an IP20/NEMA 1, UL Type 1 enclosure drive voids NEMA 1, UL Type 1
protection while maintaining IP20 conformity. This is applicable to models 2A0004 to 2A0211, 4A0002 to 4A0165, and 5A0003 to 5A0242.
