SIEP C710606 44B YASKAWA AC Drive T1000V Technical Manual
Note:
Drive output is shut off within 1 ms once the Safe Disable input has been triggered.
Protection
Functions
Motor Protection
Motor overheat protection via output current sensor
Overcurrent Protection
Drives stops when output exceeds 200% of the rated current (Heavy Duty)
Overload Protection
A stop command will be entered after operating at 150% for 60 s (Heavy Duty)
Low Voltage Protection
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)
Momentary Power Loss Ride-Thru
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.
Heatsink Overheat Protection
Protected by thermistor
Braking Resistor Overheat
Protection
Overheat input signal for braking resistor (Optional ERF-type, 3% ED)
Stall Prevention
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.
Cooling Fan Failure Protection
Circuit protection (“fan-lock” sensor)
Ground Protection
Electronic circuit protection
DC Bus Charge LED
Remains lit until DC bus voltage falls below 50 V
Environment
Storage/Installation Area
Indoors
Ambient Temperature
-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.
Humidity
95% RH or less with no condensation
Storage Temperature
-20 to +60 °C allowed for short-term transport of the product
Altitude
1000 m or less
Shock, Impact
10 to 20 Hz: 9.8 m/s

20 to 55 Hz: 5.9 m/s

Surrounding Area
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
Orientation
Install the drive vertically to maintain maximum cooling effects
Safety Regulations and Standards
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.
Protective Enclosure
IP20/IP00 heatsink-cooled drive
IP20/IP00 finless drive
Cooling Method
CIMR-TCBV0001 to 0006: self-cooled
CIMR-TCBV0010 to 0012: cooling fan
CIMR-TC2V0001 to 0004: self-cooled
CIMR-TC2V0006 to 0069: cooling fan
CIMR-TC4V0001 to 0004: self-cooled
CIMR-TC4V0005 to 0038: cooling fan
<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.
