C21 Timer operation
C22 Stage 1
•
An operation pattern from the start of
operation to automatic stop can be created.
C21
•
Select active or inactive timer operation.
0: Inactive timer operation
1: Active timer operation
C22
•
Set the time from the start of operation to
automatic stop.
Setting range: 0.00 to 3600 s
Note) If the power is turned off or the inverter is
stopped or trips during timer operation,
the counted time is reset.
C30 Frequency command 2
•
Select the frequency setting method.
For the selectable frequency setting methods,
refer to the description of F01.
C31
Analog setting signal offset
adjustment (Terminal 12)
C32 Analog setting signal offset
adjustment (Terminal C1)
•
Set the offset of the analog input (terminal
[12], terminal [C1]).
The offset can be set in the range between -
5.0 [%] and + 5.0 [%] of the maximum output
frequency (in 0.1 [%] step).
Selecting Functions
C33 Analog setting signal filter
•
The analog signal supplied to control terminal
12 or C1 sometimes includes electric noise.
Electric noise make the control unstable.
Adjust the time constant of the input filter to
remove the effects of electric noise.
Setting range: 0.00 to 5.00 s
•
With a large time constant (setting), the
control becomes stable but there is a delay in
the control response. With a small time
constant, the response is quick but the
control becomes unstable.
If the setting is not clear, change the setting
when the control is unstable or the response
is slow.
Note) The function applies to both terminals
[12] and [C1] (in common). However,
when a PID feedback signal is input,
H25 "PID control feedback filter" is
applied.
