The main characteristics of SANYO DENKI AC servoamplifiers RS1 are the following: 200VAC to 230VAC Power Supply [+10%; 15%], single-phase or three-phase (configurable by the user), with power sections kept separated for logic/signal and power electronics. Closed-loop integrated system with Position, Speed and Torque control mode. Switching Control Mode: it allows a mixed use of digital and analog signals with possibility of on fly change: position + speed; position + torque; speed + torque. Control: with pulse train (clock + direction; forward + backward pulse; 90° phase shift) or with analog signal (proportional to Speed or Torque). Optically coupled digital control I/O.3 inputs and 2 outputs with user-defined functions. Integrated management of overtravel signals. External regenerative resistor provided with sensing for maximum temperature alarm (optional). Integrated dynamic braking automatic circuit in case of alarm or power off. Setting time is reduced compared with previous Q Series. Built-in protection circuits against any overload, input overvoltage and any motor connection error (wrong encoder wiring, phase-phase and phase-ground short-circuit).
