wCK Module Series FAQ's ....

What makes the wCK Series modules unique?

Conventional Servo's are controlled by Pulse Width Modulation. The wCK Series of modules uses a multi-dropped serial network to control each module, up to 254 wCK Series modules can controlled on a single serial channel.

  1. The wCK modules have there own GPIO - 1 Analog Input (0-5V) and 2 Digital Outputs (TTL).
  2. wCK modules can be programmed to perform 8 sequence programs, this utilises parameters and variable from the wCK modules as well as the Analog Input and Digital Outputs.
  3. Conventional Servo's used for positioning applications, generally have a positioning range of 180°. The wCK Series of modules have a positioning range of 333°. In addition to this 30 speeds can be selected when positioning.
  4. When positioniong Maximum & Minimum postitions can be defined - preventing the wCK module from moving it's shaft into a position that could cause mechanical damage.
  5. Conventional Servo's are designed primarily for positioning applications, irreversible hardware modifications are required to allow a conventional servo to rotate 360°. The wCK series of modules can be programmed to act as either a positioning or a variable speed rotating device, without any hardware modifications. The wCK modules allows for 16 speeds to be selected when operating in rotating mode.
  6. The wCK modules has a programmable Over-Current setting .
  7. The wCK modules provides feedback, via the serial channel, of both position and current.
  8. The wCK modules have a feature referred to as Act Down mode. When in Act Down mode all torque is removed from the internal motor and the position is monitored. This allows the user to "teach" a series of wCK modules a movement sequence, i.e. 'paint brushing'.
  9. The wCK Series of modules allows for the Proportional, Intergral and Differential (PID) Gains to be set for each module, allowing the user to finely tune their overall control system .
