C30 Frequency Command 2 (Refer to F01.)
For details on frequency command 2, refer to the description for function code F01.
C32 Analog Input Adjustment (Gain for terminal input [12]) (Refer to F18.)
C34
Analog Input Adjustment (Gain reference point for terminal input [12])
(Refer to F18.)
C37 Analog Input Adjustment (Gain for terminal input [C1]) (Refer to F18.)
C39
Analog Input Adjustment (Gain reference point for terminal input [C1])
(Refer to F18.)
For details on adjusting the analog inputs, refer to the description for function code F18.
C33 Analog Input Adjustment (Filter for terminal input [12])
C38 Analog Input Adjustment (Filter for terminal input [C1])
C33 (voltage input) and C38 (current input) set the time constant of the filter for the analog
input on terminal [12] and [C1], respectively.
- Data setting range: 0.00 to 5.00 (sec.)
- The larger the time constant, the slower the response. Set the time constant suitable to the
load with consideration given to the system response. When the analog input fluctuates due to
electric noise, first remove the noise factor or protect the input from noise by electric means
(grounding the shield, ferrite core or capacitor). After that, increase the time constant if you
cannot remove the noise factor to a sufficiently degree.
C50 Bias (Bias reference point for frequency command 1) (Refer to F18.)
For details of setting the bias reference point for frequency command 1, refer to the descriptions
of function code F18.
C51 Bias (Bias for PID command 1)
C52 Bias (Bias reference point for PID command 1)
These function codes modify the analog input of the PID process command 1 by gain and bias,
enabling defining the arbitrary relationship between the analog input and PID process
command to be arbitrarily defined.
The actual setting is the same as that of function code F18. For details, refer to the
description of function code F18.
Note that function codes C32, C34, C37 and C39 are shared by the drive frequency
commands.
Bias (C51)
- Data setting range: -100.00 to 100.00 (%)
Bias reference point (C52)
- Data setting range: 0.00 to 100.00 (%)
