12.3

C: TUNING

The parameter group C: TUNING adjusts drive operation, including:
• Acceleration Time
• Deceleration Time
• Slip Compensation
• Torque Compensation
• Carrier Frequency
◆

C1: ACCEL / DECEL

You can set four different acceleration and deceleration time pairs in the drive. When you activate and deactivate
H1-xx = 18, 19, 61 [MFDI Function Select = Ac/Dec Time1, Ac/Dec Time2, Motor 2 Select], you can switch
acceleration and deceleration times during run.
Acceleration time parameters always set the time to accelerate from 0 Hz to E1-04 [Max Output Frequency].
Deceleration time parameters always set the time to decelerate from E1-04 to 0 Hz.
C1-01 [Accel Time 1] and C1-02 [Decel Time 1] are the default active accel/decel settings.
C1-01 [Accel Time 1]
C1-02 [Decel Time 1]
C1-03 [Accel Time 2]
C1-04 [Decel Time 2]
C1-05 [Accel Time 3]
C1-06 [Decel Time 3]
C1-07 [Accel Time 4]
C1-08 [Decel Time 4]
Note:
When C1-10 = 0 [Ac/Dec Units = 0.01s], the setting range for acceleration and deceleration times is 0.00 s to 600.00 s.

Figure 12.38 shows an operation example to change acceleration and deceleration times. It is necessary to set b1-
03 = 0 [Stopping Method Selection = Ramp->Stop] for this example.
