Reliable frequency converter with built-in EMC filter SPLC-FC1000-0R75G4 is powered by a three-phase network 380 V and uses vector control for three-phase asynchronous motors with power up to 0.7 kW voltage 380 V. Additionally, with an extra card, this converter can be connected to machines with permanent magnets.
SPLC-FC1000-0R75G4 supports several operating modes:
-
Vector control without encoder in open loop provides precise current vector control of asynchronous motor 0.7 kW and maintains its torque;
-
Vector control with encoder requires PG card installation. Rotational speed monitoring increases accuracy for speed control and allows precise torque control of asynchronous motor 0.7 kW. This mode supports synchronous motors up to 0.7 kW.
-
Scalar control V/F can be enabled for controlling asynchronous machine 0.7 kW with non-inertial load (small pumps and fans).
Brief overview of reliable frequency converter SPLC-FC1000-0R75G4:
- Mounting in protective cabinet on DIN rail;
- Front panel features a 5-character LED display and indicators for settings and control parameters display. Convenient input buttons and potentiometer handle for manual motor speed setting
- Option to connect an external control panel with RJ45 interface;
- Power terminals are closed to prevent accidental contact. STO jumper (safe torque off) can be used as an additional motor safety measure — while the jumper is installed, the frequency inverter's output is blocked. Earthing of power circuit provided.
