Switch of full-closed loop control

0: Function of full-closed loop is not used
1: Function of full-closed loop is used
2: Use the function of synchronous control
Selection of OA/OB/OZ output source

0: Motor encoder is the output source
1: Encoder of linear scale is the output source
Firmware version DSP V1.016 + CPLD 0.07(or the later version)
will provide:
2: Pulse command of CN1 is the output source
Positive / negative direction selection of linear scale feedback:

0: It is in positive direction when A phase leads B phase of linear
scale
1: It is in negative direction when B phase leads A phase of linear
scale
Filter setting of linear scale

loops is insufficient, users can set the appropriate 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 function of low-pass filter (Bypass)
The stiffness of mechanical system ↑, the setting value of P1-75 ↓
The stiffness of mechanical system ↓, the setting value of P1-75 ↑
