Calculate the Motor Acceleration Time
Use this procedure to calculate the motor acceleration time:
1. Use
A1-02 [Control Method]
to set the control method.
2. Disconnect the motor and load.
3. 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 the
E2 parameters
for induction motors. Set the
E5 parameters
for PM motors.
4. Set
C5: ASR - SPEED REGULATION
.
5. Set
C1-01 [Accel Time 1] = 0
.
6. Set
L7-01 [FW Torque Limit]
to 100%.
7. Set the frequency reference to the same value as the motor rated speed.
8. Measure the length of time for the motor to reach the rated speed.
Show
U1-05 [Motor Speed]
on the keypad and enter the Run command (forward run).
9. Stop the motor.
10. Set
n5-02
to the measured motor acceleration time value.
Reset all of the parameters that you changed to the previous setting values.

FF Control Gain
Sets the ratio between load inertia and motor inertia. Inertia Tuning automatically sets the
Feedforward Control Gain value.
1.00
(0.00 - 100.00)
When you cannot do Inertia Tuning, use this procedure to set n5-03:
Set
n5-02 [Mot Inertia Acceleration Time]
.
1. Connect the motor and load.
2. Set
C1-01 [Accel Time 1] = 0
.
3. Use
L7-01 to L7-04 [Torque Limit]
to set the expected test run torque limit levels.
4. Set the frequency reference as specified by the high speed range of the machine.
5. Measure the length of time for the motor to reach the command reference speed.
Show
U1-05 [Motor Speed]
on the keypad and enter the Run command.
6. Stop the motor.
7. Replace the values in the this formula and set
n5-03
to the value of the formula.
•
t
accel
= Acceleration time (s)
•
f
rated
= Motor rated frequency (Hz)
•
T
Lim_Test
= Test run torque limit (%)
•
f
ref_Test
= Test run frequency reference (Hz)
WARNING!
Sudden Movement Hazard. Machinery can accelerate suddenly. Do not use this function with machinery that must
not accelerate suddenly. Sudden starts can cause serious injury or death.
Reset all of the parameters that you changed to the previous setting values.
Note:
•
If response to the speed reference is slow, increase the value set in
n5-03
.
•
Increase the value set in
n5-03
when response to the speed reference is slow.
–
The speed is overshooting.
–
A negative torque reference is output when acceleration ends.
