YASKAWA TOEPYAIGA8002B GA800 Drive Programming 247
2.4 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 Select = 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.
Parameter Range
C1-01 [Acceleration Time 1]
0.0 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]
Note:
The setting range for acceleration and deceleration times is 0.00 to 600.00 s when C1-10 = 0 [Accel/Decel Time Setting Units = 0.01 s (0.00
to 600.00 s)] .
■
Use MFDIs to Switch Acceleration Times
Table 2.29 shows the different acceleration and deceleration times.

Active Parameter
Acceleration Time Deceleration Time
OFF OFF C1-01 [Acceleration Time 1] C1-02 [Deceleration Time 1]
ON OFF C1-03 [Acceleration Time 2] C1-04 [Deceleration Time 2]
OFF ON C1-05 [Acceleration Time 3] C1-06 [Deceleration Time 3]
ON ON C1-07 [Acceleration Time 4] C1-08 [Deceleration Time 4]
Figure 2.44 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.
