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 two different acceleration and deceleration time pairs in the drive. When you activate and deactivate H1-
xx = 7 [MFDI Function Selection = Accel/Decel Time Selection], 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
C1-01 [Acceleration Time 1]
C1-02 [Deceleration Time 1]
C1-03 [Acceleration Time 2]
C1-04 [Deceleration Time 2]

Use MFDIs to Switch Acceleration Times
Table 5.29 shows the different acceleration and deceleration times.

Figure 5.29 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.
