11.4 C: Tuning
C parameters
adjust drive operation, including:
•
Acceleration Time
•
Deceleration Time
•
Slip Compensation
•
Torque Compensation
•
Carrier Frequency
◆
C1: Accel & Decel Time
You can set four different acceleration and deceleration time pairs in the drive. When you activate and deactivate
H1-xx = 7, 16, 1A [MFDI Function Selection = Accel/Decel Time Selection 1, Motor 2 Selection, Accel/Decel
Time Selection 2], you can switch acceleration and deceleration times during run.
Acceleration time parameters always set the time to accelerate from 0 Hz to
E1-04 [Maximum Output Frequency]
.
Deceleration time parameters always set the time to decelerate from
E1-04
to 0 Hz.
C1-01 [Acceleration Time 1]
and
C1-02 [Deceleration Time 1]
are the default active accel/decel settings.
Parameters
Setting Range
C1-01 [Acceleration Time 1]
0.0 s to 6000.0 s
C1-02 [Deceleration Time 1]
C1-03 [Acceleration Time 2]
C1-04 [Deceleration Time 2]
C1-05 [Acceleration Time 3]
C1-06 [Deceleration Time 3]
C1-07 [Acceleration Time 4]
C1-08 [Deceleration Time 4]
C1-22 [Acceleration Time 1]
C1-23 [Deceleration Time 1]
C1-24 [Acceleration Time 2]
C1-25 [Deceleration Time 2]
Note:
When
C1-10 = 0 [Accel/Decel Time Setting Units = 0.01 s (0.00 to 600.00 s)]
, the setting range for acceleration and deceleration times
is
0.00 s to 600.00 s
.
■
Use MFDIs to Switch Acceleration Times
Select the different acceleration and deceleration times as shown in the following table.
H1-xx = 7
[Accel/Decel Time Selection

H1-xx = 1A
[Accel/Decel Time Selection
2]

The following figure shows an operation example to change acceleration and deceleration times. It is necessary to
set
b1-03 = 0 [Stopping Method Selection = Ramp to Stop]
for this example.
