The ZoneLink® .S Driver Module connects to and operates a Holjeron or Sparks Microroller motorized roller. It provides a run signal, a speed adjustment potentiometer and a rotation direction command to the motor.The “.S” technology enables serial communication between the driver module and a ZoneLink Controller.

Through this innovative link, the ZoneLink Controller can configure a .S Driver Module for an application, control it and obtain information about the status of the driver module, as well as about the connected motor.Up to four ZoneLink .S Driver Modules can be connected to a ZoneLink 4-Zone Controller using standard category 5 patch cables and RJ-45 connectors. The zone sensor hardwires directly to the .S Driver Module, keeping all wiring local to a zone and reducing wiring.The ZoneLink .S Driver Module uses microcontroller-based commutation of the brushless motor, which provides the following key benefits:

• Predictive diagnostics embedded in the .S Driver Module monitor the motor condition and provide a flag to the control system when a powered roller should be replaced—in advance of the roller failing.

• Closed-loop speed control holds the roller speed at a constant value, improving the ability to tune a conveyor system.
