 Freewheel diode must be connected.
3. Position command pulse interfaces (C3)
There are both differential and single end connections. The differential connection is
recommended and the twisted pair wire is used suitably. The drive current is in the range of 8 to
15mA.The operation mode is set by parameter P035: Pulse + direction, CCW/ CW pulse, A phase
+ B phase (orthogonal pulse).
C3-1: Differential drive C3-2: single end drive
 Maximum pulse frequency is
500kHz(kpps)
；
 This connection is recommended in
order to avoid interference.
 Maximum pulse frequency is
200kHz(kpps)
；
 recommend the value of resistor R:
VCC R
5V 82
Ω ~120 Ω
12V 510 Ω ~820 Ω
24V 1.5k Ω ~2k Ω
4. Analog command input interfaces (C4)
There are both differential and single end connections. The differential input connection is
recommended. The speed and the torque use the same analog input. The input is in the range of
-10V~+10V.The input impedance is approximately 10k. There is normally a zero-bias at analog
input and can be compensated by the parameter setting.

 Needs 3 line connections with the host
controller;
 Strong anti-common mode
 Needs 2 line connections with the host
controller;
 AGND connects with AS- on the
