The PML Series is a general purpose family of drives for brushless DC (electronically commutated) motors. With either a 115 VAC or 230 VAC line source, our drives can control motors that vary in the 90 to 280 VDC range, up to 5 amps or 1.5 HP. With the use of on-board trim pots, you can quickly set the maximum and minimum speeds, acceleration and deceleration rates, motoring and regening current limits, and the proportional and integral feedback gains. Each drive is designed for feedback from 120° hall effect sensors, and can be commanded with a wide range of analog inputs with our built-in isolation.
The onboard microprocessor allows for custom programming for OEMs. Whether it’s as simple as changing the purpose of a jumper, input, or trim pot, to programming entire routines and behaviors specific only to the OEMs application, the PML is great for integrating PLC like functionality into your operation. Doing this can eliminate the need of a separate PLC altogether or enhance a system that currently does not have one.
The PML Series is certified to the new UL 61800-5-1 Standard, meaning not only does it contain isolation for remote control from an analog signal, but also has internal Motor Overload Protection circuitry. If a motor requests more amperage than the motor overload protection setting, the drive begins an internal countdown until faulting out. The higher the overload condition, the faster the countdown. With motor overload protection built into the PML Series, users won’t have to install expensive external devices to perform this function to meet future UL requirements.
