L3-24: Motor Accel Time @ Rated Torque

(046E)

Motor Accel Time @ Rated
Torque
Sets the motor acceleration time to reach the maximum frequency at the motor rated torque for
stopped single-drive motors.
Determined by o2-04, E2-11,
and E5-01
(0.001 - 10.000 s)
Set one of these parameters to enable L3-24 :
• L2-29 = 1 [Kinetic Energy Backup Method = Single Drive KEB Ride-Thru 2]
• L3-04 = 2 [Stall Prevention during Decel = Intelligent (Ignore Decel Ramp)]
• L3-11 = 1 [Overvoltage Suppression Select = Enabled]
• H1-xx = 7A or 7B [MFDI Function Selection = KEB Ride-Thru 2 Activate (N.O./N.C.)]
Note:
When Auto-Tuning changes the value of E2-11 [Motor Rated Power] , the drive will automatically set L3-24 to the value for a Yaskawa
standard motor (4 poles). When you use a PM motor, the drive uses the value in E5-01 [PM Motor Code Selection] to change L3-24 .
Manually Adjust Parameters
Use this formula to find the motor acceleration time:
• J
Motor
= Moment of inertia of motor (kg m 2 )
• n
rated
= Motor rated speed (min -1 , r/min)
• T
rated
= Motor rated torque (N∙m)
The rated torque is calculated using the following expression.
P
Motor
= Motor Rated Power (kW)

Load Inertia Ratio
Sets the ratio between motor inertia and machine inertia.
1.0
(0.1 - 1000.0)
Set one of these parameters to enable L3-25 :
•
L2-29 = 1 [Kinetic Energy Backup Method = Single Drive KEB Ride-Thru 2]
•
L3-04 = 2 [Stall Prevention during Decel = Intelligent (Ignore Decel Ramp)]
•
L3-11 = 1 [Overvoltage Suppression Select= Enabled]
•
H1-xx = 7A or 7B [MFDI Function Selection = KEB Ride-Thru 2 Activate (N.O./N.C.)]
Note:
•
If you set this value incorrectly when L2-29 = 1 , H1-xx = 7A or 7B , or L3-11 = 1 , it can cause large current ripples and ov [Overvoltage] ,
Uv1 [DC Bus Undervoltage] , or oC [Overcurrent] faults.
• KEB Tuning will automatically set this value.
