Tolomatic servo and stepper drives can be controlled from a PLC or master controller via 24VDC digital I/O, 0 to 10VDC or 4 to 20mA analog I/O, Ethernet or Modbus RTU over RS-485 (EtherNet/IP or Modbus TCP protocols).
Used with pump and conveyor technologies, the NORD SK 180E decentralized AC vector drive features 3 digital inputs, 2 digital outputs, 2 analog inputs, an integrated 24V power supply and an onboard AS interface.
Providing microdrive control for variable-torque pump loads through 25hp, the Yaskawa iQpump Micro intelligent pump drive comes in NEMA 1- and NEMA 4X-rated models; NEMA 3R-configured packages are available.
Designed to move air in HVAC applications, the Mitsubishi F800 Series low-voltage variable frequency drive can be used with air handlers, cooling towers and pumps; it also controls and supports a range of motor types, including AC induction and permanent magnet motors.
The VACON 100 FLOW AC drive controls the flow and pressure of a maximum of 8 pumps (or fans) without an external controller; it is equipped with built-in Ethernet for commissioning and maintenance, as well as local or remote monitoring.
