PARAMETERS
66
Note:1. The multi-speeds can also be set in the PU or DeviceNet operation mode.
2. For 3-s
eed settin
, if two or three s
eeds are simultaneousl
selected,
priority is given to the frequency setting of the lower signal.
3. Pr. 24 to Pr. 27 and Pr. 232 to Pr. 239 settin
s have no
riorit
between
them.
4. The parameter values can be changed during operation.
5. When in

Pr. 180
to Pr. 183, the other functions ma
be affected. Check the functions of the
corresponding terminals (DeviceNet input) before making setting.

Pr. 44, Pr. 45)
"
Acceleration/deceleration time (Pr. 7, Pr. 8, Pr. 20, Pr. 21, Pr. 44, Pr. 45)
Pr. 7 "acceleration time"
Pr. 8 "deceleration time"
Pr. 20 "acceleration/deceleration reference frequency"
Pr. 21 "acceleration/deceleration time increments"
Pr. 44 "second acceleration/deceleration time"
Pr. 45 "second deceleration time"
Used to set motor acceleration/deceleration time.
Set a larger value for a slower speed increase/decrease or a smaller value for a faster
speed increase/decrease.
