190V(220V system)or 380V(440V system).
3.When KEB function enabled,the inverter decelerate to zero by 2-08,and the inverter stop.
4.IF the power on signal enabled during the KEB function ,the inverter accelerate to original
frequency.
Parameter Group 3 - Operating Parameters
3-00: Frequency Upper limit(Hz) : 0.01 - 650.00
3-01: Frequency Lower limit(Hz) : 0.01 - 650.00
Internal frequency
3-00 (upper frequency limit)
3-01 (lower frequency limit)
(note)
※Note: When 3-01 = 0 Hz and frequency command is 0 Hz, the inverter will stop at 0 speed.
When 3-01 > 0 Hz and frequency command ≦3-01, the inverter will output 3-01 preset
value.
3-02 : Acceleration Time #1 (second): 0.1 – 3600.0
3-03 : Deceleration Time #1 (second): 0.1 – 3600.0
3-04 : S Curve of First Acceleration Stage (second): 0.0 – 4.0
3-05 : S Curve of Second Acceleration Stage (second): 0.0 – 4.0
3-06 : Acceleration Time #2 (second): 0.1 – 3600.0
3-07 : Deceleration Time #2 (second): 0.1 – 3600.0
3-08 : Jog Acceleration Time (second): 0.1 –25.5
3-09 : Jog Deceleration Time (second): 0.1 – 25.5
1.) Formula for calculating acceleration and deceleration time: The denominator is base on the
rated frequency of motor.
Preset frequency Preset frequency
Acceleration time = 3-02 (or 3-06) x
,Deceleration time = 3-03 (or 3-07) x
0-05
0-05
2.)When 5-00 – 5-06 is set 06 (the second acceleration and deceleration time), the first
acceleration/ deceleration/ S curve or the second acceleration/ deceleration/ S curve will be
selected by off or on the external input terminal.
3.) When 5-00 – 5-06 is set 05 (Jog), Jog run is controlled by external terminals. The acceleration
and deceleration action will be at Jog acceleration and deceleration time.
4.)When 5-00 – 5-06 is set as 05(Jog) and 06(acceleration and deceleration time toggle), to
change the acceleration and deceleration time by ON the external terminals, and the list
setting:
