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 o f the multi-function input terminals (H1-DD=16).
No.

■ C1-15: Inspection Deceleration Ramp
Sets the deceleration ramp during Inspection Run. Refer to
Inspection Operation on page 109
for details.
No.

C1-15
Inspection Deceleration Ramp
0.00 to 2.00 s <1>
0.00 s <1>
<1> The setting range and default value depend on the display units set in param eter o1-03. I f o1-03 is set between 0 and 4, the time required to go
from 0% speed to 100% maximum speed is expressed in seconds. I f o1-03 is set to 5 or 6, then setting units will appear in m /s2 or ft/s2. I f the
drive is in V /f control mode, the inspection deceleration ram p can be set in seconds only.
♦ 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 o f the acceleration or deceleration.
No.
Parameter Name
C2-01
Jerk at A ccel Start
C2-02
Jerk at A ccel End
C2-03
Jerk at D ecel Start
C 2-04
Jerk at D ecel End
C2-05
Jerk below Leveling Speed
Setting Range
Default
0.00 to 10.00 s <1>
0.50 s <1>
<1> The setting range and default value depend on the display units set in param eter o1-03. I f o1-03 is set between 0 and 4, the time required to go
from 0% speed to 100% maximum speed is expressed in seconds. I f o1-03 is set to 5 or 6, then setting units will appear in m /s2 or ft/s2.

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 s (C2-01 + C2-02) / 2
Actual decel ramp = decel ramp s (C2-03 + C2-04) / 2
