A.4 Drive Specifications
356 YASKAWA ELECTRIC SIEP C710616 30B YASKAWA AC Drive T1000A Technical Manual
<1> Select control modes in accordance with the drive capacity.
<2> 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.
<3> Ensure that Stall Prevention is disabled 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.
<4> 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.
<5> Actual specifications may vary according to motor characteristics.
<6> Overload protection may be triggered when operating with 150% of the rated output current if the output frequency is less than 6 Hz.
<7> May be shorter due to load conditions and motor speed.
<8> A separate Momentary Power Loss Ride-Thru Unit is required for the drives CIMR-T2A0004 to 2A0056 and T4A0002 to 4A0031 if the
application needs to continue running during a momentary power loss up to 2 seconds.
<9> 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.
<10> Up to 3000 m with output current and voltage derating. Refer to Altitude Derating on page 361 for details.
