PWM32 旋转涂布机 headway research inc PWM32 Microprocessor Sequence Controller Up to 9 steps in one recipe Memory for up to 10 user-designed recipes User-set in each step: rpm, ramp (accel/decel), time, various I/O for accessory control (dispensers, exhaust control, lid/doors, etc. Speed can be manually adjusted while a recipe is running Operator can manually turn on the vacuum to the chuck, overriding AUTO control LCD interface for user input prompting and process display RS485 port for future communication and add-on equipment use An optional accessory stand is available for the controller. It permits the controller to sit on a tabletop surface, inclined upward toward the operator. It may also alternately be used to suspend the controller underneath a tabletop, inclined upward toward the operator. The basic controller can control simple dispensers at minimal cost for additional dispenser hardware. Controller I/O allows output of 2 fluids. The PWM 32 controller can directly replace many older SCR type controllers (EC101 and PM101) for improved PWM performance, as well as the other new features. A trade-in credit will be given on applicable EC/PM101 spinners or controllers. Typically, dispensers used on EC/PM101 spinners will not work with the PWM32 control. It may be possible at the factory to adapt such dispensers, or to use applicable parts in building a compatible dispenser.
