Torque control mode. In this mode, the servo converter operates as a motor armature current controller. When setting an analogue reference within the range from -10 to +10 V, the armature current and, correspondingly, the torque of the motor shaft will vary from –Mmax to +Mmax.
Speed control mode. In this mode, the servo converter operates as a speed controller. When setting an analogue reference within the range from -10 to +10 V, the motor shaft speed will vary from –Nmax to +Nmax. When using a tachogenerator or an encoder as an external feedback sensor, the speed control coefficient corresponds to that indicated in the Technical Specification. In the speed control mode with compensation of the armature voltage drop (I*R), the speed control range is not less than 1:50. Therefore, an electric drive without external feedback sensor can only be used in cases where there is no need in operation on creeping speeds. Also possible is dual-zone control of a separately excited DC motor. In this case, the armature control should be performed by the a servo converter of XDC-200 Series, and the excitation current control should be performed using a servo converter of XDC-100 Series.
Position control mode. In this mode servo converter operates as controller of the motor shaft angular position. The sensor of position feedback is encoder. Servo converter can coordinate the reference discreteness with encoder discreteness. For one count of reference signal, the motor shaft can pass from 1 to 16 encoder counts. The matching coefficient can set by rotary DIP switch.
General Description
Control system. The servo amplifier is based on a cascade control system, consisting of a PID controller of speed/position and PI current controller. Control system and protection system are software implemented on the basis of microcontroller.
Power supply. The servo amplifier has a separate power circuit for converter and its power section. The servo amplifier can be powered by AC or DC. The power section can be powered by three-phase or single-phase current, and DC. Single-phase power supply is recommended for use for the electric motor rotor current up to 10A. When necessary to coordinate the supply voltage to the voltage of the electric motor, an additional transformer is used.
Power Section. The power section of the servo converter is based on the H-bridge on IGBT or MOSFET transistors. The frequency of the Pulse Width Modulation (PWM) of the amplifier is 8 kHz. To avoid any excessive currents when you switch on the network, servo amplifier contains scheme of smooth charging of filtering capacitors. To avoid overvoltage in the DC, the link servo amplifier converter has a chopper with brake resistor.
Connecting the Electric motor. The servo amplifier is designed to work with one electric motor. The servo amplifier allows you to connect most types of electric motors without additional. However, using electric motors with low rotor inductance, such as motors with disc rotor, the series extra inductance must be connected.
Secondary power supply. The servo converter contains secondary power supply that are derived on connectors and available for use as follows,
• +10 V, -10 V – to power an external analog adjuster (of potentiometer);
• +5 V, +15 V, +24 V – to power the feedback encoder, digital inputs, an auxiliary fan. All secondary power supplies have a galvanic isolation from the power unit and the power supply voltage of the servo converter.
Analog inputs. Analog inputs, namely the input of the reference and the input of the feedback (of Tachogenerators), have a galvanic isolation from power unit and power supply voltage of servo converter, but have a common ground with the secondary power supply. The servo converter contains elements of sensitivity setting of feedback input that allows you to apply tachogenerators with different output voltage.
Digital inputs. Under digital inputs, it means «Enable», the inputs of discrete reference and the input of the encoder signal. Each digital input has galvanic isolation of all circles of servo amplifier and other digital inputs. Each digital input has its own input voltage settings (sensitivity) and protected against turning on the reverse polarity. This allows a flexible configuration of the servo converter.
Digital outputs. The servo amplifier has two digital outputs - output "Ready" and the output of the control of the brake coupling. Both digital outputs are relay, normally open, not linked.
Brake coupling control. The servo converter allows you to control brake coupling of electric motor. Switching on the coupling happens after giving a signal to «Enable» on the readiness of the servo converters and the turning off occurs after its removal and stop of the electric motor. After triggering the protections, switching off the coupling occurs instantaneously.
The servo controllers design. The servo converters is made in a single design as a unit and proposed to be installed in electrical cabinets. The servo amplifier orientation is vertical, with power terminal block into the down. The necessary parts to configure the regulators and indicators located on the front board and are accessible for user.
