 Analog input bias/gain calibration (C16 (Pr.919) to C19 (Pr.920))
• The "bias"/"gain" function can adjust the relation between the torque and the torque limit setting input signal. Examples of
setting input signals are 0 to 5 VDC or 0 to 10 VDC, and they are externally input.
• Set the bias torque of the terminal 1 input using C16 (Pr.919). (The initial value is the torque at 0 V.)
• Use C18 (Pr.920) to set the torque to the torque setting voltage set by Pr.73 Analog input selection. (The initial value is the
torque at 10 V.)

Calibration example of terminal 1
*1 When a negative voltage (0 to -10 V (-5 V)) is input, the torque limit value becomes "0".
• There are three methods to adjust the bias/gain torque setting voltage.
Adjustment by applying voltage between terminals 1 and 5 to set the voltage at the bias/gain torque.

Adjustment by selecting the voltage at the bias/gain torque without applying voltage between terminals 1 and 5.
