The RACOmatic® CONTROL. This optimizes the performance and life of the RACO electric actuator.

Configuration A

Two adjustable end positions

• Position-accurate approach with 2 adjustable end positions
• Adjustable acceleration and deceleration ramps
• Force limitation up to the set maximum force
• Output of the position signal
• Limitation of the position parameters as a protective function
• Speed is adjustable via potentiometer
• Error message output

Configuration

The RACOmatic^® is controlled via two digital control inputs (extend and retract). The movement command is executed until the set end position has been reached precisely.

Feedback is provided as an output signal when the respective end position is reached. The device also has a error message output. The adjustment speed of the RACOmatic^® can be set on the device via a potentiometer.

Application Example

For open/close actuation of dampers where large masses also need to be accelerated and decelerated. The ramps for acceleration and deceleration can be parameterized. This avoids shocks and impacts and minimizes stress on the mechanical components. The end positions are approached precisely.

Configuration B

8 adjustable positions

• Precise approach to 8 adjustable end positions
• Adjustable acceleration and deceleration ramps
• Force limitation up to the set maximum force
• Output of the position signal
• Position limitation as a protective function
• Adjustable Speed via potentiometer
• Error message output

Configuration

Up to 8 fixed positions are conveniently set via the RACOmatic^® parameterization tool and selected in binary form during operation via three digital inputs. As soon as the enable input is activated, the selected position is approached precisely via the set ramps and speeds. A digital output reports back when the new position has been reached. The position parameters can only be set within the factory-set limits. Your drive is optimally protected. The adjustment speed of the RACOmatic^® can be set on the device using a potentiometer.

Application Example

Up to 8 adjustable positions can be approached with pinpoint accuracy. For example, this could be used to make adjustments on devices and machines for different component sizes, height adjustment, or a sorting switch adjustment.

Configuration C

Stroke-controlled electric actuator

• Movement to any number of positions
• Adjustable acceleration and deceleration ramps
• Adjustable Thrust up to the Set Maximum Force
• Digital output for "position reached"
• Adjustable speed via potentiometer

Configuration

The position setpoint is specified via an analog signal (4-20mA or 0-10V), which specifies the path linearly over the set end position range. The position control is activated via an enable signal and the electric actuator moves to the target position at the set speed via the programmed ramps. Feedback of the current actual position value is provided via an analog output and additionally via a digital output "position reached." The adjustment speed of the RACOmatic^® can be set on the device via a potentiometer.

Application Examples

Best suited for positioning and control tasks, examples include: metering slides, material distribution flaps, or valves with continuous adjustment travel. Positioning accuracy is approximately 1% of the adjustment travel. Adjustable ramps for smooth acceleration and deceleration of large masses. Analog and digital position feedback.

Configuration D

Power-operated electric actuator

• Control for extension and retraction
• Force-controlled stopping and holding of the force
• Adjustable Thrust up to the Set Maximum Force
• Analog output of the actual position and the actual force
• Adjustable Speed via potentiometer
• Error message output

Configuration

The travel command for extension and retraction is issued via two digital control inputs. The adjustment force (0-100% of the maximum force) is specified via the analog input. When the set target force is reached, the RACO Electric Actuator^® stops and maintains this force. The current actual position and force are output via analog signals. When the respective programmed position is reached, signaling takes place via one digital output each. The device also has a fault output. The adjustment speed is set onsite using a potentiometer.

Application Examples

This configuration is the first choice for processes requiring joining/pressing, material test benches that require force control, or for producing a defined force for pressing on closures, container lids and/or flaps. The behavior of the RACO Electric actuators^® is similar to that of a hydraulic actuator with pressure limitation. Analog force setpoint specification and analog signal feedback for displacement and force enable the process to be controlled and monitored.

Configuration E

Variable control via fieldbus interface

• Control of operating parameters (acceleration, force, position)
• Switchable controlparameters , even during the process
• Integration via fieldbus interface
• Profinet interface module
• Precise output of operating parameters
• Dedicated fault messages
• Force limitation adjustable up to maximum force
• Fault message output

Configuration

The electric actuator is controlled via the fieldbus interface. A variety of fieldbus connection modules are available (PROFIBUS, CANopen, DeviceNet and EtherCAT). Access to the operating and function parameters allows the operator to specify force, position, speed, ramps, etc. flexibly and at any time from the Level II system. Actual values such as the position or the motor current (proportional to the actual force value) can be read out at any time via the fieldbus. This provides a high degree of flexibility, To ensure that the fieldbus interface and control unit are ready for operation even when the main voltage is switched off, the customer must always provide the 24V DC control voltage.

Application Example

Variably controlled axes or feeds for positioning with high precision. The customer can provide the visualization of setting and operating parameters. Optional switchover between a travel-controlled or a force-controlled electric actuator, e.g., in testing and press-fit devices, docking stations, or transfer devices on machines.

Configuration F

Synchronized Control

• Precise positioning of up to 4 RACO Eelectric actuators^® in synchronization
• Adjustable acceleration and deceleration ramps
• Force limitation adjustable up to maximum force
• Precise output of the operating parameters
• Analog output of the position signal
• Error message signal output

Configuration

Synchronized control of 2 to 4 electric actuators according to the master/follower principle. The master is controlled via the RACOmatic^® between programmable positions. The follower drives are linked to the master drive via their RACOmatic^® by means of an internal bus connection and follow the master by continuously communicating its actual position and current speed to the connected units. The RACO torque control system monitors and controls the motor current and thus the torque or adjustment force of all drives, which enables them to be positioned against a stop/seal provided by the customer at the defined support point. A programmable creep speed enables the drive to run at a low adjustment speed when the fixed stop is reached.

Application Examples

Typical applications include: Lifting bridges, lifting gates on dams, furnace lifting doors, lifting devices, press molds, cover actuators, and tensioning devices for trough chain conveyors. In these cases, it is ensured that load monitoring of the drives is carried out during the process and that the RACO torque control system ensures "safe shutdown" at the point of contact. This means that the lift bridge rests securely and in a defined manner on the counter bearing or that the cover or lift gate is pressed into the seal with a specified force. In the event of a malfunction or if one of the drives is replaced, synchronization can be easily restarted using the controls on the RACO PLC. The components are connected via extremely robust industrial plug connectors.
