1.3 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 slip compensation, torque
compensation, and carrier frequency.
◆ C1: Acceleration and Deceleration Times
■ C1-01 to C1-08: Accel/Decel Times 1 to 4
Four 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 to the maximum
output frequency (E1-04). Deceleration time parameters always set the time to decelerate
from maximum output frequency to 0. C1-01 and C1-02 are the default active accel/decel
settings.
Switching Acceleration Times by Digital Inputs
Accel/decel. times 1 are active by default if no input is set. The accel/decel times 2, 3 and 4
can be activated by digital inputs (H1-= 7 and 1A) as explained in Table 1.24.
Table 1.24 Accel/decel. Time Selection by Digital Input
No.
<1> The setting range for the acceleration and deceleration times is determined by C1-10 (Accel/Decel Time Setting
Units). For example, if the time is set in units of 0.01 s (C1-10 = 0), the setting range becomes 0.00 to 600.00 s.
