5.3 C: Tuning
C parameters are used to set the acceleration and deceleration characteristics, as well as S-curves. Other parameters in
this group cover settings for torque compensation, and carrier frequency.
◆ C1: Acceleration and Deceleration Times
■ C1-01 to C1-04: Accel, Decel Time 1/2
Two different sets of acceleration and deceleration times can be set in the drive. They can be selected by digital inputs, by
the motor selection, or can be switched automatically. Acceleration time parameters always set the time to accelerate
from 0 Hz to the maximum output frequency (E1-04). Deceleration time parameters always set the time to decelerate
from maximum output frequency to 0 Hz. C1-01 and C1-02 are the default active accel/decel settings.
Switching Acceleration Times by Digital Input
Accel/decel time 1 are active by default if no input is set. The accel/decel time 2 can be activated by digital inputs (H1-
 = 7) as explained in Table 5.12.
Table 5.12 Accel/Decel Time Selection by Digital Input
Figure 5.19 shows an operation example for changing accel/decel. times. The example below requires that the stopping
method be set for “Ramp to stop” (b1-03 = 0).
