Settings：
 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
0: BYPASS
1: 20Mhz
2: 10Mhz
3: 6.66Mhz
4: 1.66Mhz
5: 833K
6: 416K
Take 20Mhz(50ns) as the example:
If the width of single-phase pulse is smaller than 50ns, the signal
will be filtered.
