Protection Design
<1> Select control modes in accordance with 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> 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.
<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 depending on 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 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.
<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> Models CIMR-Ao4A0930 and 4A1200 are rated at 5.9 m/s
<11> Terminals H1, H2, DM+, and DM- on 600 V class models are designed to the functionality, but are not certified to Insulation coordination: class
1.
<12> Removing the top protective cover or bottom conduit bracket from an IP20/NEMA Type 1 enclosure drive voids NEMA Type 1 protection while
maintaining IP20 conformity. This is applicable to models 2A0004 to 2A0211, 4A0002 to 4A0165, and 5A0003 to 5A0099.
