5 Run the servo system
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.
5-2．Basic function setting
Switch the motor rotate direction
Servo immediately stop torque
Prohibit forward running /P-OT
Prohibit reverse running /N-OT
