 In position control mode, the terminals function as
position command input terminals.
 In other control modes, the terminals are invalid.
 The maximum input pulse frequency is 4 MHz in
differential mode and 200 kHz in open collector
mode.

 AD1 and AD2 are accurate to 12 bits.
 For external analog input terminals,
the input impedance is 13kΩ, and the
input voltage ranges from -10V to
+10V. If the voltage is out of the range
of -11V–+11V, the drive may be
damaged.
 The range, offset, and function
definition are configurable.

Phase-A output
 The output of encoder signal that is frequency
divided is compliant with TIA/EIA-422-B.
 The output phase-A pulse and phase-B pulse are
still orthogonal. In forward rotation, phase A leads
phase B by 90°. In reverse rotation, phase B leads
phase A by 90°.
 The frequency can be divided or multiplied by any
integer or fraction.
