Dual Digital PID Unit

Designed primarily for systems integrators and panel builders, the PLA allows you to enhance and simplify any analogue or digital drive control system. It can reduce or eliminate the need for costly PLC or PC based systems.
You can use the PLA to work with a range of industrial applications. Easy to use configurable software blocks offer you a powerful and flexible method of processing analogue and digital signals.
A 4-button keypad and a large alpha-numeric display make it easy to quickly navigate through an extensive range of software functions. And with the included windows based configuration and monitoring software, PL Pilot makes overcoming even the most difficult of motion tasks quick and simple.
To make it easier for you to integrate the PLA into your control system, the drives are fully isolated and have a small footprint. The PLA have a number of fieldbus communications options, including: Profibus, DeviceNet, CC-Link, EtherNet/IP, and CANopen.
The PLA is also compatible with drive.web. The drive.web distributed control technology uses Ethernet and powerful graphical tools to provide robust, Programmable Peer Control (PPC) for drives and systems. The drive.web technology is infinitely scalable and cost effective for systems of any size of complexity. For typical motor control systems, it beats using any PLC on cost, performance and ease of use.

Standard Software Function Blocks

  • Diameter calculator
  • Taper tension calculator
  • Torque compensation for inertia and friction
  • Latch with set, reset, clock and data inputs
  • Batch counter with roll-over facility
  • 4-change over switches
  • 3-input digital decoder with 8 programmable output values
  • 4-Quadrant parameter profiler with Linear, square, cubic or 4th power profiling laws
  • Motorized pot simulator with power loss memory
  • 2-high performance PID's with gain profiling
  • 2-Summers with inverting scaling clamping and hysterisis.
  • 2-Filters with precision time constants from milliseconds to 30 secs
  • Delay timer with roll over facility
  • Linear or 'S' ramp with independent up down rates for forward and reverse
  • 4-comparators with programmable hysterisis and aperture option
  • 8-Multifunction blocks with: AND, OR, INVERT, SIGN CHANGE, RECTIFY, COMPARE
All the above 'precision instruments' can be programmed and interconnected with each other and/or the extensive input/output facilities in the PLA. Making connections between blocks, parameters and I/O's very easy using the PLA's GOTO and GETFROM tools with all source and target parameters described in full English or selectable other languages. Accidental user programmed short circuit connections are automatically flagged by the built in 'Conflict Checker'.

Comprehensive Input / Output Facilities

  • 8-bipolar analogue inputs with programmable range, scalers, offset and clamps
  • 3-analogue outputs with programmable scaler, rectifier and offset
  • 4-Digital input/outputs with programmable logic threshold and selectable invert
  • All digital outputs have an output capability up to 350mA short circuit protected
  • An isolated bipolar input suitable for voltages up to +/-1000V DC
  • 8-Digital inputs with adjustable comparator threshold
  • 4-Digital inputs that can also be used as encoder inputs up to 100 KHz
  • 3-Digital outputs with programmable logic threshold and selectable invert
  • A high voltage input suitable for tachogenerators or other sources up to +/-200V
  • An isolated input suitable for measuring AC voltages up to 690VAC
All of the above inputs can be programmed and monitored in engineering units using the superb diagnostic facilities available within the PLA.
Signals can also be analyzed further using the scope facility that can be configured to operate through analogue output 3 of the PLA; thus any parameter viewed on the alphanumeric display of the PLA can also be monitored using an oscilloscope across this output. PL Pilot also enables the user to save entire application configurations to disk or to save just the configuration of an individual block (i.e. the PID settings); these can then form the basis of a library that the user can call upon for other applications. The user can also save up to 3 complete PLA configurations within the unit.
