Description

Overview

Essential details：TBF120/7R Pulse Width Modulated 4-Quadrant Servo Controller PARKER

The series R amplifiers (= resolver) are servo amplifiers for speed control of brushless servo motors. They extract the information for the sine commutation of the motor and for the speed feedback from the signals of the resolver, attached to the motor. In addition to that, incremental encoder signals are simulated by these signals. This allows the realization of favorable solutions for a large range of applications with low and medium power levels.
The amplifiers work with a pulse-width modulated power amplifier in MOSFET technique. The design is a 3 HE (Euroformat) for 19″ slide-in racks. These devices have an integrated power supply unit. The electronics is supplied internally from the intermediate circuit voltage, which also allows a battery-powered operation.
The main characteristics are:
· Sine commutation
· Hybrid technique/ SMD technology
· 19 inch/3HE slide-in technique
· Internal power supply unit
· High dynamics
· High efficiency
· Almost no clock noise by doubling of the current frequency
· Short-circuit proof and ground contact proof
· Protective circuit: Undervoltage, overvoltage, overcurrent, overheating
· I 2t current limiting
· Differential amplifier input
· Enable input
· External current limiting
· Limit switch inputs
· PLC compatible inputs
· Incremental encoder simulation

The speed control loop consists of speed controller, circuit, motor and speed measurement. The nominal speed value is externally given, e.g. through potentiometer, NC control or something similar. The actual speed value is determined at the motor shaft by a resolver. The difference between nominal value and actual value is formed at the summing point and transmitted to the speed controller. The speed controller then defines the required current set value.
The current control loop consists of the current controllers, the amplifier stage, the current measurement and the motor windings. The current set values available at the output of the current controller, control the six power switches of the inverter through a pulse-width modulator. With a PWM frequency of 9.5kHz this leads, due to the special activation, to a current ripple of 19kHz and consequently to a merely audible clock noise.
This secondary control loop (current) under another one (speed) guarantees a stable control with good dynamics and high rigidity of the drive. This even allows the easy realization of current limitations, necessary to protect the motor and the amplifier, just by limiting the output voltage of the speed controller (current set value).
