FUNCTION C
ODES
Switching between frequency command 1 (F01) and 2 (C30)
Frequency command 1 (F01) and 2 (C30) can be switched by the external input signal
Hz2/Hz1 ("Select frequency command 2/1") assigned to any digital input terminal.
For details about Hz2/Hz1 , refer to the description of E01 through E07 (data = 11).
Digital input signal Hz2/Hz1 Frequency command source
OFF Frequency command 1 (F01)
ON Frequency command 2 (C30)
„
Offset (C31, C36, C41)
C31, C36 or C41 specifies an offset for analog input voltage or current. The offset also
applies to signals sent from the external equipment.
„
Filter time constant (C33, C38, C43)
C33, C38, or C43 specifies a filter time constant for analog input voltage or current. Choose
an appropriate value for the time constant taking into account the response speed of the
machinery system since a large time constant slows down the response. When the input
voltage fluctuates due to noise, specify a larger time constant.
„
Polarity (C35, C45)
C35 or C45 specifies the input range for analog input voltage.
Data for C35/C45 Terminal input specifications
0 -10 to +10 VDC
1 0 to +10 VDC (negative value of voltage is regarded as 0 V)
„
Terminal [C1] Input Range Selection (C40)
C40 specifies the input range of terminal [C1] (analog input current).
Data for C40 Terminal [C1] input range
0 4 to 20 mA (factory default)
1 0 to 20 mA
