4.2.25 Acceleration/deceleration curve selection
You can set different patterns of motor acceleration and deceleration
according to the type of system to be driven by the inverter.
Use functions "A097" and "A098" to select acceleration and
deceleration patterns, respectively.
You can individually set an acceleration pattern for acceleration and a deceleration pattern for deceleration.
When the acceleration/deceleration pattern is set other than 00 (linear) using analog input as frequency source is to
be avoided because it prolongs the acceleration or deceleration time.

Descrip-
tion
With this pattern, the
motor is accelerated or
decelerated linearly until
its speed reaches the set
output frequency.
This pattern is effective
for preventing the
collapse of cargo carried
by a lift or conveyor
driven by the inverter.
This pattern is effective for the tension control on a
winding machine driven by the inverter (to prevent
cutting of the object to be wound).
This pattern is similar
to the S-curve pattern
for the shockless
starting and stopping of
the motor, except that
the middle section of
this pattern is linear.

- Terminal 3 function p.30
- Switch sw1 is set to on the input terminal setting for said terminal is automatically changed to no no function assigned when slide switch sw1 is set to on to prevent any duplication of terminal functions even if slide switch sw1 is subsequently returned to off the original function setting for said terminal will not be restored if necessary the original function will have to be re assigned to said terminal p.30
- Switch sw1 is set to off to disable the function p.30
- Signal logic is improper the inverter trips due to emergency stop e37 if this occurs check and correct the wiring and signal logic and then input the reset rs signal only the reset rs signal input from intelligent input terminal 1 can release the inverter from tripping due to emergency stop e37 the inverter cannot be released from the e37 status by any operation from the digital operator p.30
- Of the main circuit elements therefore do not touch any terminals of the inverter or any power lines e g motor cables otherwise electric shock injury or ground fault may result p.30
- Note the emergency stop function does not electrically shut off the inverter but merely stops the switching operation p.30
- Note if intelligent input terminal 3 is left unconnected the cable connected to the terminal is disconnected or the p.30
- Note before operating slide switch sw1 make sure that the input power supply is off p.30
