The PMC-53100 is a high speed Stepper Motor Controller, implemented into the most reliable embedded card fromat, the PC/104. The PMC-53100 Controller is based on 3 programmable pulse generator LSI chip that can operate up to 3 Stepper Motor simultaneously, while keeping the host computer free of motor's profilebuilding, motor's step counting and other motor controlling tasks. The PMC-53100 provides an automatic linear acceleration/deceleration profile option, with a 50% output pulse form, and with an output rate of up to 32000 steps per second. Motor controlling is achieved by either a DOS or WINDOWS application software provided by the manufacturer, or by the customer's own written software, making use of the manufacturer's most simple, yet powerful, WINDOWS 9x/NT DLLs. All Motor's output control lines and all motor's feedback lines are optically isolated, avoiding interference of motor's high EMI/RFI noise emission. The combination of these features makes the PMC-53100 the most reliable solution for stepper motor control.
