GENERAL DESCRIPTION SANYO DENKI, the world leader in the motion control industry, has recently presented the R Series Brushless Servoamplifiers, coupled with servomotors P series and Q series, entrusting R.T.A. with their distribution. The available motorization covers a 50 W to 3 KW power range, with maximum torque up to 28 Nm. The motors, equipped with built-in encoder for all versions and featuring maximum speed up to 4,500 rpm, are among the most compact in the world and, coupled with proposed servoamplifiers, are characterized by an excellent dynamic

behavior. This product selection offered by R.T.A., chosen from among the models on SANYO DENKI catalogue and supported by a consistent stock of motors and amplifiers always available in stock, makes it possible to face and solve a wide range of automation problems with maximum efficiency. TECHNICAL FEATURES - DRIVES The main characteristics of drives are listed below: 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. Scale factor that can be set by the user on both analog and frequency inputs and on the repetition of the encoder signal. . PNP/NPN/Differential frequency interface, with digital filter that can be configured by the user for noise immunity.. Integrated management of overtravel signals. Double built-in fully automatic notch filter to remove the system’s resonance frequency. 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. External regenerative resistor provided with sensing for maximum temperature alarm (optional). . 200VAC to 230VAC Power Supply [+10%; –15%], single-phase or three-phase (can be set by operator). Power sections kept separated for logic/signal and power electronics Built-in protection circuits against any overload, input overvoltage and any motor connection error (wrong encoder wiring, phase-phase and phase-ground short-circuit). The amplifier can be set and monitored by a PC. with RS 232 interface. Dynamic braking circuit activated when the power section is not powered or in case of alarm.
