<1> Speed control accuracy varies somewhat according to the type of motor and drive settings. Contact Yaskawa for
more information.
<2> Instantaneous average deceleration torque refers to the torque required to decelerate the motor (uncoupled from
the load) from 60 Hz in the shortest time.
<3> Ensure that Stall Prevention Selection during Deceleration is disabled (L3-04 = 0) or set to 3 when using a braking
resistor or the Braking Resistor Unit. The default setting for the stall prevention function will interfere with the
braking resistor.
<4> Overload protection may be triggered when operating with 150% of the rated output current if the output
frequency is less than 6 Hz.
<5> Parameter settings allow up to 150 V.
<6> A Momentary Power Loss Ridethru Unit is required for 200/400V class drives 7.5 kW and less if the application
needs to continue running during a momentary power loss up to 2 seconds.
<7> Ground protection cannot be provided under the following circumstances when a ground fault is likely in the
motor windings during run: Low ground resistance for the motor cable and terminal block; low ground resistance
for the motor cable and terminal block; or the drive is powered up from a ground short.
<8> Drive output is interrupted in less than 1 ms after the safety input is activated.
