NEMA 1 inverter drives in 40 hp, 50 hp, 60 hp
Lenze Americas, manufacturer of electrical and mechanical drives, motion control and automation technology, recently introduced three new SMVector NEMA 1 models. The drives are among Lenze technologies now showing at Pack Expo 2011, booth S5360. The 40 hp, 50 hp and 60 hp SMVector drives are expected to deliver superior performance and design flexibility in a broad range of ac motor applications.
“The workhorse of the Lenze inverter portfolio, SMVector drives are deployed in diverse applications—from packaging and conveying to material handling, positive displacement pumping, and HVAC systems,” said Steve Dextraze, inverter product manager, Lenze Americas.
SMVector drives have four modes of operation – V/Hz, enhanced V/Hz, vector speed, and torque – plus high starting torque, auto-tuning, advanced low-speed control, and dynamic speed regulation, suitable for many applications. Designed by Lenze as a universally applicable inverter, the SMVector has an input voltage ranging from 120 V ac 1-phase to 600 V ac, 3-phase. The removable EPM (electronic programming module) memory chip allows customers to store operational memory and parameter settings for fast and efficient programming of multiple drives.
Accompanied by a major software upgrade, the new SMVector 40 hp, 50 hp, and 60 hp drives feature sequencer mode operation where up to 16 segments can be set, each at an individual frequency set-point, acceleration/deceleration time, digital output state, and analog input value. Advanced setup parameters include analog input configuration, deceleration override time, voltage midpoint and frequency midpoint V/Hz characteristics.
Plug-in communication modules make the SMVector easily integrated into commonly used industrial networks, including Modbus/RS485, DeviceNet, CANopen, Profibus DP and EtherNet/IP, among others. Programmable digital and analog I/O allow SMVector drives to be configured for application-specific tasks, such as presetting multiple speeds, electronic braking, and motor jogging. The integrated dynamic brake connection requires only an external resistor for fast stopping or deceleration.
