Tripless AC drives
The X200 Series volts/Hertz inverter is a variable-frequency drive suited for fan, pump, conveyor and other general-purpose applications. The unit's Safe Stop feature provides a hardware-based emergency stop function. Other features include a function that decelerates and stops the motor using regenerative energy from the load when ac power is lost; improved trip avoidance; automatic energy saving; built-in timing logic; analog input math (PLC), and a RS-485 Modbus/RTU communication interface.
