A.4 Drive Specifications
392 YASKAWA ELECTRIC SIEP C710616 27C YASKAWA AC Drive A1000 Technical Manual
<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> 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.
<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 according to 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 the drives CIMR-A2A0004 through 2A0056 and 4A0002 through 4A0031
if the application needs to continue running during a momentary power loss up to 2 s.
<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 ground
fault is present at the output.
<9> Removing the top protective cover from a NEMA Type 1 enclosure drive voids the NEMA Type 1 protection but still keeps IP20 conformity.
This is applicable to models 2A0004 to 2A0081 and 4A0002 to 4A0044.
