∨ key) adjustment clear ". Refer to P20.01~P20.10 for details.
1: Digital setting (P10.02) + terminal UP/DOWN adjustment
When the drive is powered up, the value of P10.02 is taken as the master frequency
command. This frequency can be adjusted via "terminal UP" and "terminal DOWN" no matter
the drive is running or in stop.
When this parameter value is selected, following parameter setting should be performed:
1) Set the two digital input terminals to "terminal UP" and "terminal DOWN" respectively.
Refer to P20.01~P20.10 for further information.
2) Set terminal UP/DOWN frequency change step size (P20.18).
3) Set P20.17 (terminal UP/DOWN frequency adjustment treatment).

ATTENTION:
Frequency adjustment via terminal UP and DOWN can be cleared through terminal "UP/DOWN
(including ∧/∨ key) adjustment clear" . Refer to P20.01~P20.10 for details.
2: Analog input AI1
AI1 are(0~10V) voltage input and (4~20mA) current input programmable. Voltage or
current input can be selected through toggle switches J3 on control board.J3 defaults to
0~10V input voltage, J3 turns to 4-20mA input voltage when it is up.
Refer to specification of P22.00~P22. 20 for corresponding relation between analog input
and output frequency.
See parameter Group C4 for automatic correction of analog input.
3: Analog input AI2
AI2 input is the -10V~+10V voltage input, and the plus-minus of voltage determines the
setting direction of frequency.
Refer to detailed description of P22.00~P22.20 for corresponding relation between analog
input and output frequency.
4: Reserved
5: X6/DI pulse input
If this parameter value selected, command frequency will be determined by pulse frequency
input via terminal X6/DI only. In such a case, P20.07 should be set to 24. Corresponding
relation between pulse frequency and command frequency is specified in P22.24~P22.27.
6: Process PID output
Command frequency is determined by process closed-loop PID computation result. See
parameter Group P50 for details.
7: PLC
Command frequency is determined by simple PLC. See parameter Group P52 for details.
8: Multi-step speed
A total of 16-step speed settings can be realized through status combination of "multi-step
frequency terminal 1~4". please see multi-function input terminals in detail
