Velocity mode  Digitial input signal  15
Prole velocity mode, after drive is enabled. The drive 
will run at velocity set by P-21 (JS). NO run/stop signal, 
X2 is direction switch.
Velocity mode  Digitial input signal  16
Prole velocity mode, after drive is enabled. The drive 
will run at velocity set by P-21 (JS). NO run/stop signal, 
X2 is direction switch.
Multi velocity mode Digitial input signal  17
Prole velocity mode, NO run/stop signal. X2 is 
direction switch. X10, X11, X12 is speed selection 
switch.  
Multi velocity mode Digitial input signal  18
Prole velocity mode, X1 is run/stop switch. X2 is 
direction switch. X10, X11, X12 is speed selection 
switch.
Point to point Velocity SCL command  21
Use SCL command to control point to point position 
mode.
Analog position mode +10~-10V Analog signal 22 Use analog input voltage signal for position control .
Position table Internal position mode 25
