| | | New generation GREATORK actuators incorporate optional intelligent frequency conversion | | |
| | | |
| | | Excellent capability ♦ Throughout Motor Protection ♦ Syncrophase protection from incorrect wiring ♦ Motor chambers integrated with actuators ♦ Operation Optimization through motor speed controlling | | |
| | | Performance Data NewAVAF and AVATF actuators incorporate intelligent frequency conversion GREATORK AVAF/AVATF range is developed from AVA/AVAT, which incorporates motor frequency conversion and Dc servo motor technologies to fulfill accurate on-off switch and sustain frequent modulation. AVAF range are integrated with intelligent frequency conversion module, and AVATF with DC industrial servo motor unit, instead of conventional motor redirecting relay for increased reliability. All AVAF/AVATF range output axes have 8 speed levels for customers' self-configuration, electronic position controlled and electronic torque protected, internal supervision and motor protection enabled. The newly AVAF/AVATF ranges have full compatibility with all communication protocol including MODBUS RTU, PROFIBUS-DP, FOUNDATION-H1. | | |
