Function Acceleration Time
Function 2C Acceleration Time
Function 2E Acceleration Time
Function 2b Deceleration Time
Function 2d Deceleration Time
Function 2F Deceleration Time
-- The time between 0 to fmax and from to 0
can be set anywhere between 0.2 to 3600 sec-
onds.
-- Accel and time can be selected from four
acceleration and deceleration groups
using the and terminals.
-- Even during acceleration and deceleration,
time can be changed using the exter-
nal contact signals and RT2.
Function 30 Pattern I

Linear 0
Curve 1
Curve 2
NOTE: Linear pattern will override Pattern B if
fmax is greater than 60 Hz.
NOTE: This function cannot be used in the event
Multi-Step Frequency selection is made.
Function 31 Tone Control Selection
There are four different tone control selections that
set the chopping frequency of the inverter output
transistors. This can be used to reduce audible
resonant frequencies from the motor.
32 Overload Early Warning Signal
An early warning signal is given if the inverter
output current exceeds the overload alarm level for
a certain period of time.
This is an open collector output. If the optional relay
unit is used, this signal can be used as a dry contact
output.
If is set, this function is inactive.
