<1> Speed control accuracy varies somewhat according to the type of motor and drive settings.
<2> 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.
<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 Ride-Thru Unit is required for 200/400 V 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> If an installation altitude exceeds 1000 m, contact Yaskawa or your Yaskawa agent for consultation.
Note: Drive output is shut off within 1 ms once the Safe Disable input has been triggered.

Motor overheat protection via output current sensor
Drives stops when output exceeds 200% of the rated current (Heavy Duty)
A stop command will be entered after operating at 150% for 60 s (Heavy Duty)
Drive stops when DC bus voltage falls below the levels indicated:
190 V (3-phase 200 V), 160 V (single-phase 200 V), 380 V (3-phase 400 V), 350 V (3-
phase 380 V)
3 selections available: Ride-Thru disabled (stops after 15 ms), time base of 0.5 s, and
continue running as long as the drive control board is powered up.
Protected by thermistor
Overheat input signal for braking resistor (Optional ERF-type, 3% ED)
Stall prevention is available during acceleration, deceleration, and during run. Separate
settings for each type of stall prevention determine the current level at which stall
prevention is triggered.

Remains lit until DC bus voltage falls below 50 V
Indoors
-10 to +50 °C (heatsink-cooled drive)
-10 to +50 °C (finless drive)
If using the heatsink-cooled drive in temperatures greater than 50 °C and finless drive
in temperature greater than 35 °C, either takes steps to ensure proper airflow around the
unit or derate drive capacity. Refer to Ambient Temperature Derating on page 24 for
details.

Install the drive in an area free from:
• oil mist and dust
• metal shavings, oil, water or other foreign materials
• radioactive materials
• combustible materials
• harmful gases and liquids
• excessive vibration
• chlorides
• direct sunlight
Install the drive vertically to maintain maximum cooling effects
One Safe Disable input according to ISO13849-1 Cat. 3 PLd, IEC61508 SIL2; Time
from input open to drive output stop is less than 1 ms.
