High speed photo isolation input.
Working mode is set by parameter FA14:
 Pulse+direction.
 CCW/CW pulse.
 A、B orthogonal pulse input.
 Input of internal position control.

The output circuit of instruction pulse of the upper device side can be selected from the
differential output or collector open circuit output . Its maximum input frequency and minimum
pulse width are shown in the following table:

 If the output pulse width of the upper device is less than the minimum pulse
width, it will cause the drive to receive error pulses.
 The terminal between PULS+ and PULS-/SIGN+ and SIGN- only support
below 5V signal. If over than 5V, it needs to connect external resistances.
