Note: Entry of a reverse rotation command with the
run command and produces no inverter operation. The rotation direction should be specified
by the data of C21 to C28.
Note: When an pattern operation is commanded via input terminals, the self-hold function of
a run command does not work. Use an alternate switch if necessary.
Note: After completion of a cycle of pattern operation, the inverter decelerates to a stop with
the deceleration time specified by F08 (Deceleration time 1).
C30 Frequency Command 2
For details of frequency command 2, refer to the description of F01.
C31 to C35 Analog Input Adjustment for [12]
C36 to C39 (Offset, Gain, Filter time constant, Gain base point, Polarity)
C41 to C45 Analog Input Adjustment for [C1]
C40 (Offset, Gain, Filter time constant, Gain base point)
Analog Input Adjustment for [V2]
(Offset, Gain, Filter time constant, Gain base point, Polarity)
Terminal [C1] Input Range Selection
Setting up a reference frequency using analog input
You can adjust the gain, polarity, filter time constant, and offset which are applied to analog
inputs (voltage inputs to terminals [12] and [V2], and current input to terminal [C1]).

Offset (C31, C36, C41)

C31, C36 or C41 configures an offset for an analog voltage/current input. The offset also
applies to signals sent from the external equipment.
- Data setting range: -5.0 to +5.0 (%)
Filter time constant (C33, C38, C43)

C33, C38 or C43 configures a filter time constant for an analog voltage/current input. The
larger the time constant, the slower the response. Specify the proper filter time constant
taking into account the response speed of the machine (load). If the input voltage fluctuates
due to line noises, increase the time constant.
- Data setting range: 0.00 to 5.00 (s)
