Function Code Parameter Name Setting Range Default
F0-25
Acceleration/Deceleration
time base frequency
0: Maximum frequency (F0-10)
1: Set frequency
2: 100 Hz
0
The acceleration/deceleration time indicates the time for the AC drive to increase from 0
Hz to the frequency set in F0-25. If this parameter is set to 1, the acceleration/deceleration
time is related to the set frequency. If the set frequency changes frequently, the motor's
acceleration/deceleration also changes.
Function Code Parameter Name Setting Range Default
F0-26
Base frequency for UP/DOWN
modication during running
0: Running frequency
1: Set frequency
0
This parameter is valid only when the frequency source is digital setting.
It is used to set the base frequency to be modified by using keys and or the
terminal UP/DOWN function. If the running frequency and set frequency are different, there
will be a large difference between the AC drive's performance during the acceleration/
deceleration process.
Function Code Parameter Name Setting Range Default
F0-27
Binding command
source to
frequency source
Unit's digit (Binding operation panel
command to frequency source)
000
0: No binding
1: Frequency source by digital setting
2: AI1
3: AI2
4: AI3
5: Pulse setting (DI5)
6: Multi-reference
7: Simple PLC
8: PID
9: Communication setting
Ten's digit (Binding terminal command to
frequency source)
0–9, same as unit's digit
Hundred's digit (Binding communication
command to frequency source)
0–9, same as unit's digit)
It is used to bind the three running command sources with the nine frequency sources,
facilitating to implement synchronous switchover.
For details on the frequency sources, see the description of F0-03 (Main frequency source X
selection). Different running command sources can be bound to the same frequency source.
