Figure 12.130 Configure Feed Forward Control
■
Before You Use Feed Forward Control
Do one of these procedures before you use feed forward control.
•
Run Auto-Tuning to set motor parameters.
When you cannot do Auto-Tuning, manually set motor parameters with the information on the motor nameplate
or test reports. Set
E2: MOTOR 1 PARAMETERS
for induction motors. Set
E5: PM MOTOR SETTINGS
for PM
motors.
•
Set
C5: ASR - SPEED REGULATION
individually to adjust the speed control loop (ASR).
•
If you can connect a motor to a machine and rotate it during Auto-Tuning, do Inertia Tuning.
The drive automatically adjusts feed forward parameters during Inertia Tuning.
•
If you cannot do Inertia Tuning, refer to
and set the parameters related to feed forward control
individually.

Mot Inertia Acceleration
Time
Sets the length of time for the motor to accelerate from the stopped to the maximum frequency
with a single motor at the rated torque. Inertia Tuning automatically sets the motor acceleration
time.
Determined by C6-01, E5-
01, and o2-04
(0.001 - 10.000 s)
If you cannot do Inertia Tuning, calculate the motor acceleration time as shown here or measure the motor
acceleration time and set
n5-02
to this value.
Calculate the Motor Acceleration Time
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)
You can also use this formula to find the motor acceleration time:
•
f
rated
= Motor rated frequency (Hz)
•
P = Number of motor poles
