A.4 Drive Specifications

Standards
Protection Design
<1> Select control modes in accordance with the drive capacity.
<2> High-frequency current superposition (n8-57 = 1) can be set.
<3> Rotational Auto Tuning must be performed.
<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> 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.
<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 according to 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 the drives CIMR-A2A0004 through 2A0056 and 4A0002 through
4A0031 if the application needs to continue running during a momentary power loss up to 2 s.
<12> A 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.
<13> Up to 3000 m with output current and voltage derating. Refer to
<14> Models CIMR-A4A0930 and 4A1200 are rated at 5.9 m/s
<15> This is applicable for drives with Rev. B or higher.
<16> Removing the top protective cover from an IP20/NEMA 1, UL Type 1 enclosure drive voids the NEMA 1, UL Type 1 protection but still
keeps IP20 conformity. This is applicable to models 2A0004 to 2A0081 and 4A0002 to 4A0044.
