DVET series

Product catalog summary

Main Features
The DVET series vector inverters are designed for controlling three-phase asynchronous motors with feedback from speed sensors. They offer easy setup, flexibility, high performance, and exceptional torque at any speed, including zero rpm, with quiet and efficient operation.

Special Functions

Motor Interface: Auto test for speed sensor, U V W phases connection, and motor poles number. Measurement of motor characteristics such as stator resistance, leakage inductance, magnetising current, and rotor/stator time constant. Auto tuning of current and flux regulators and line compensation for rotor resistance variation.
Technology and Control: Features include regulation systems with speed, flux, or voltage and current loop, max torque and current set points, regeneration function, DC voltage limitation in braking mode, and inverter temperature self-monitoring.
Feedback Possibilities: Supports TTL line driver encoder, Sin/Cos encoder, and resolver.
Additional Functions: Electrical gearing, master/slave function, continuous positioning control, and indexing function for spindle applications.
