C31 to C33 Analog Input Adjustment for [12] (Offset) (Gain) (Filter time constant)
C36 to C38 Analog Input Adjustment for [V2] (C1 function) (Offset) (Gain) (Filter time
constant)
C41 to C43 Analog Input Adjustment for [V2] (V2 function) (Offset) (Gain) (Filter time
constant)
These function codes specify the gain, offset, and filter time constant for analog input terminals.
■
Offset (C31, C36, and C41)
These function codes specify the offset adjustment for analog input voltage or current.
- Data setting range: -100.0 to 100.0 (%)
■
Gain (C32, C37, and C42)
These function codes specify the gain adjustment for analog input voltage or current.
- Data setting range: 0.00 to 200.00 (%)
■
Command values
The following formula indicates the relationship between the command value, gain (%), offset (%),
and analog input (%).
Command value = (Analog input - Offset) × Gain × Reference value
Where, the analog input -100 to 100% corresponds to -10 to 10 V in voltage input, and 0 to 100%, to
4 to 20 mA in current input.
The table below lists the reference values and limits.
Commands Reference values Limits
Reference speed (pre-ramp) Maximum speed Maximum speed × -100 to 100%
Reference torque bias 100% of motor rated torque Motor rated torque × -200 to 200%
Setting F01 to "1: Analog speed command (Not reversible)" limits the reference speed (pre-ramp) at
0% or 100% of the maximum speed.
