[Pr.300] Servo input axis type
Set the current value type to be generated of the input value for the servo input axis.
Setting value Description
0: Invalid Servo input axis is invalid.
1: Current feed value Generate the input value based on "[Md.20] Feed current value (D0+20n, D1+20n)".
2: Real current value Generate the input value based on the real current value, which is converted units of the encoder feedback pulses from the
servo amplifier.
3: Servo command value Generate the input value based on the command pulse (encoder pulse units) to the servo amplifier.
4: Feedback value Generate the input value based on the encoder feedback pulse from the servo amplifier.
Motion CPU
1: Current feed value
2: Real current value
[Pr.301] Servo input axis smoothing time constant
Set the averaging time to execute a smoothing process for the input travel value from the servo input axis. The smoothing
process can moderate speed fluctuation, when the "Real current value" or "Feedback value" is used as input values.
The input response is delayed depending on the time corresponding to the setting by smoothing process setting.

Setting details
Set the current value type to be
generated of the input value for the
servo input axis.
Set to smooth the input value.
Set the time to advance or delay the
phase.
Set the time constant to affect the phase
compensation.
Set this parameter to restrict the input
travel value to one direction.
