5-1.Control mode selection 
DS2  series  servo  has  one  main  mode  and  two  sub  modes.  Sub  mode  1  and  2  can  be 
switched to each other via /C-SEL signal. 
Testing mode, users cannot change! 
The motor will not power on even if the servo drive enables. 
Torque control (internal setting) 
Control  the  output  torque  of  servo  motor  via  operating  panel  or 
communication. 
Torque control (analog voltage command) 
Control  the  output  torque  of  servo  motor  via  analog  voltage 
command. It is mostly used to close-loop torque control with upper 
device, such as tension control. (If servo drive doesn’t have analog 
input port, it cannot use this mode.) 
Speed control (internal speed setting) 
Use /SPD-D, /SPD-A, /SPD-B to select the speed which is set in 
the servo drive. The servo drive can set 3 speeds. 
Speed control (analog voltage command) 
Control the speed of servo motor via analog voltage command. It is 
mostly used to close-loop speed control with upper device. 
Position control (internal position command) 
Control the position via internal position command; it can set pulse 
quantity and torque. 
Position control (external pulse command) 
Control the position of servo motor via pulse command. Control the 
position via pulse quantity; control the speed via pulse frequency. 
Speed control (pulse frequency command) 
Control  the  speed  of  servo  motor  via  pulse  frequency,  but  not 
control the position. 
The servo will enter sub mode2 when /C-SEL signal is effective.
