12.3 C: Tuning
YASKAWA SIEPYEULA5001C LA500 Technical Manual 291
When the output speed is at the C1-11 value, the drive automatically switches the acceleration and deceleration
times. Set this parameter to 0.0% to disable this function.
■ C1-15: Inspect Dec Ramp
No.
(Hex.)
Name Description
Default
(Range)
C1-15
(0260)
Inspect Dec Ramp
Sets the deceleration ramp used for inspection run.
0.00 s
(0.00 - 2.00 s)
◆ C2: Jerk Characteristics
Use Jerk characteristics to smooth acceleration and deceleration and to minimize abrupt shock to the load.
Set Jerk characteristic time during acceleration/deceleration at start and acceleration/deceleration at stop.
The following figure explains how Jerk are applied.
Figure 12.5 Jerk Timing Diagram - Forward/Reverse Operation
When o1-03 is set to between 0 and 4, the jerk settings are expressed in seconds. Then the actual accel/decel time
including jerk settings can be calculated as follows:
• Actual accel ramp = accel ramp setting + (C2-01 + C2-02) / 2
• Actual decel ramp = decel ramp setting + (C2-03 + C2-04) / 2
