Linear Actuator Control Systems
Get the most from your Nook linear actuator products by adding a complete control system to manage the most challenging industrial lifting, positioning, and transfer operations within your process.
Nook provides custom turn-key and stand alone linear motion control solutions that expand process flexibility while increasing throughput.
Any Nook linear actuator device (Jacks, PA/Modular Actuators, or Electric Cylinders) can be paired with a variety of AC or DC motors. In addition, these linear motion systems can be controlled with custom configured control systems. These systems typically consist of a motor, control panel, and control device (HMI, Pendant, switch, etc...). Nook electric control systems can be configured to support unlimited applications in any industry from basic jogging functions to complex automated operations.
Our applications team will closely collaborate with you to understand the specifics of your application to provide the best possible motion control solution. Nook control systems are highly configurable to meet your individual project requirements, schedule, and budget.
Basic Features and Options
AC or DC Controls
- PLC (Programmable Logic Controller) - Control peripheral devices and read analog/encoder inputs. They easily facilitate process changes and equipment upgrades.
- HMI (Human Machine Interface) - Touch screen and central system control allowing for fast setup and easy troubleshooting. They minimize hardware (push buttons/indicators/switches) while being highly versatile and configurable. HMI's reduce downtime by monitoring system status information (including fault messages).
- VFD (Variable Frequency Drives) - Speed control for electric AC or DC motors. Ideal for synchronization, positioning, or variable speed applications. VFD's can be programmed to ramp up/down or accelerate/decelerate over a given time period.
- MDS (Main Disconnect Switch) - Connect/Disconnect main facility power to the control panel. They can be locked out and tagged out as a safety precaution when necessary.
- E-Stop (Emergency Stop) - Typically an illuminated or non-illuminated push button used to stop equipment emergency situations.
- Terminal Blocks and Wiring - Both are clearly labeled for easy field installation and troubleshooting.
- Panel Meter - Display feedback from a number of input devices (including position). They use input from potentiometers, linear sensors, encoders, or other analog devices.
Other Features and Options Include:
- NEMA Enclosures
- Electrical Schematics
- UL Certifications (Optional)
- Motor Overload Protection
- Safety Relays
- Linear Sensors
- Incremental Encoders - Provide digital pulses monitored by PLC or VFD used to synchronize, position, or vary the speed of an electric motor. They can be mounted on limit switches, reducers, or electric motors. Incremental encoders offer a variety of different pulses per revolution (PPR) - One up to several thousand PPM are possible.
- Absolute Encoders - Pulses or counts are monitored by a PLC or VFD. Ethernet/IP encoders communicate with a PLC over an Ethernet cable. Absolute encoders do not lose position or counts
when power is cycled (homing not required).
- Potentiometers - Output a 0 – 10 VDC analog output signal used to scale the position of a device. Rotary types can be mounted on limit switches while string types are typically mounted to equipment. Potentiometers ideal for lower accuracy applications.
- Linear Sensors - Output a 0 – 10 VDC, or 4 – 20mA analog output signal used to scale, position, or control an electric motor. Linear sensors provide the highest degree of accuracy and come in a variety of configurations including rod, magnetic, and non-contact.
- Load Cells - Feedback devices that detect load (tension, compression, or both). Load cells like linear sensors come in a variety of configurations such as pancake, donut, or pin style.
- Provide smooth, reliable synchronization of multiple axes of motion while maintaining the tight positioning tolerances required for each application. Nook provides a variety of solutions for 2 to 6 axes of motion synchronization. These systems are designed to increase process efficiency by providing safe and dependable performance.
- Allows two or more electric motors to be moved in the same direction together in applications that cannot be mechanically coupled.
- Electrically couples the electric motors using positional feedback from multiple motors to hold a tolerance using multiple types of feedback as well as motor control devices.
- Positioning applications move an electric motor to a specific position using an AC, DC, or servo motor along with a feedback device. Servo motors and certain AC and DC motors have encoders mounted on the motor. Devices run in a closed loop to accurately position the electric motor (typically using HMI).
- Variable speed motion allows an electric motor to be moved at various speeds in applications where the process changes frequently (and where the motor needs to start slowly and ramp up to speed). HMIs, speed pots, and selector switches can be used to vary the speed of an electric motor.
- Allows speed drive set point adjustment between while in motion. Custom speeds can be easily entered via numeric keypad.
- The simplest and most common type of motion. Momentary jogging requires the user to press and hold a push button to jog the motor (and stops upon button release). Maintained jogging is accomplished through a one-time command such as pressing and releasing a push button. Maintained jogging stops when the user presses the stop push button or the motor reaches a limit switch.
- Adaptable range of precision positioning options for single or multiple axes of motion.
- Provides easy operation and reliable service.
