Function:
Select the ramp type, depending on
requirements for acceleration/deceleration. A
linear ramp gives constant acceleration during
ramping. An S-ramp gives non-linear
acceleration.
S-ramp based on the values set in
parameter 3-61 Ramp 3 Ramp up Time and
parameter 3-62 Ramp 3 Ramp down Time.
Function:
Enter the ramp-up time, which is the
acceleration time from 0 Hz to the rated
motor speed n . Select a ramp-up time
s
such that the output current does not
exceed the current limit in
parameter 4-18 Current Limit during
ramping. See ramp-down time in
parameter 3-62 Ramp 3 Ramp down Time.
Function:
Enter the ramp-down time, which is the
deceleration time from the rated motor
speed n to 0 Hz. Select a ramp-down time
s
such that no overvoltage arises in the
inverter due to regenerative operation of the
motor, and such that the generated current
does not exceed the current limit set in
parameter 4-18 Current Limit. See ramp-up
time in parameter 3-61 Ramp 3 Ramp up
Time.

motor speed n . Select a ramp-up time

such that no overvoltage arises in the

Function:
[0.01 Enter the jog ramp time, which is the
acceleration/deceleration time between 0 Hz
and the rated motor frequency n
the resulting output current required for the
given jog ramp time does not exceed the
current limit in parameter 4-18 Current Limit.
The jog ramp time starts when activating a
jog signal via the LCP, a selected digital
output, or the serial communication port.
When jog state is disabled, the normal
ramping times are valid.
