174 YASKAWA ELECTRIC SIEP C710616 38F YASKAWA AC Drive - L1000A Technical Manual
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.
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-=16).
■
C1-15: Inspection Deceleration Ramp
Sets the deceleration ramp during Inspection Run. Refer to Inspection Operation on page 128 for details.
◆ 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.
<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
2
or ft/s

. If the
drive is in V/f control mode, the Fast stop ramp can be set in seconds only.
