
Z: positive / negative direction selection of linear scale feedback
0: positive direction when A phase leads B phase of linear scale
1: positive direction when B phase leads A phase of linear scale

U: linear scale filter function
0: bypass
1: 6.66 M
2: 1.66 M

P1.075
Low-pass filter time constant for full- and half-closed loop
control
Address: 0196H
0197H
Default:
100
Control mode: PT
Unit: ms Setting range: 0 – 1000
Format: DEC Data size: 16-bit
Settings:
When the stiffness of the mechanical system between full- and half-closed loops is insufficient, set the
proper time constant to enhance the stability of the system. In other words, temporarily create the
half-closed loop effect, and after stabilizing, the full-closed loop effect is created. When the stiffness is
sufficient, set to bypass.
Set the value to 0 to disable the low-pass filter (bypass) function.
If the stiffness of the mechanical system is high, decrease the value of P1.075, or set the value to 0 to
disable. If the stiffness of the mechanical system is low, increase the value of P1.075.
P1.076
▲
Maximum speed for encoder output (OA, OB)
Address: 0198H
0199H
Default: 5500 Control mode: All
Unit: rpm Setting range: 0 – 6000
Format: DEC Data size: 16-bit
Settings:
Input the actual maximum speed of the motor as the reference value to activate the smoothing function.
When you set the value to 0, the smoothing function is disabled.
