C2: Jerk Settings - YASKAWA L1000A Technical Manual

5.3 C: Tuning
A Fast Stop can be selected as the action the drive should take when certain faults occur, such as L8-03 (Overheat Pre-
Alarm Operation Selection).
No.
C1-09
<1> The setting range and default value depend on the display units set in parameter o1-03. If o1-03 is set between 0 and 4, the time required to go
from 0% speed to 100% maximum speed is expressed in seconds. If o1-03 is set to 5 or 6, then setting units will appear in m/s
drive is in V/f control mode, the Fast stop ramp can be set in seconds only.
NOTICE: Rapid deceleration can trigger an overvoltage fault. The drive output shuts off when faulted and the motor coasts. Set an
appropriate Fast Stop time to C1-09 to avoid this uncontrolled motor state and to ensure that the motor stops quickly and safely.

C1-10: Accel/Decel Setting Resolution
Determines the units for the acceleration and deceleration ramps set to C1-01 through C1-09 using parameter C1-10.
No.
C1-10
Setting 0: Two decimal places
Setting 1: One decimal place

C1-12/C1-13: Motor 2 Acceleration Time/Motor 2 Deceleration Time
Sets the accel/decel time when motor 2 has been selected using one of the multi-function input terminals (H1-

◆ C2: Jerk Settings

Jerk settings set the transition between acceleration rates. Adjust them to smooth out jerks or shocks that occur when the
speed is changed.

C2-01 to C2-05: Jerk Settings
C2-01 through C2-05 set separate jerks for each section of the acceleration or deceleration.
No.
