Reliable frequency converter with built-in EMC filter SPLC-FC1000-3R7G4 powered by a three-phase network 380 V and uses vector control for three-phase asynchronous motors with power up to 3.7 kW voltage 380 V. Additionally, with the installation of an additional card, this frequency converter can be connected to a machine with permanent magnets.
SPLC-FC1000-3R7G4 supports several operating modes:
-
Vector control without encoder in open loop provides precise control of the current vector for asynchronous electric motor 3.7 kW and maintains torque on it;
-
Vector control with encoder requires installation of PG card. RPM tracking allows to increase speed control accuracy and enables precise control of the rotational moment of the asynchronous electric motor 3.7 kW. In this mode, synchronous motors up to 3.7 kW can be operated.
-
Scalar control V/F can be enabled for controlling an asynchronous electric machine 3.7 kW with non-inertia load (small pumps and fans).
Overview of the reliable frequency converter SPLC-FC1000-3R7G4:
- Mounted in a protective cabinet on a DIN-rail;
- On the front panel — 5-digit LED display and indicators for displaying settings and control parameters values. Convenient input buttons and potentiometer knob for manually setting motor rotation frequency
- Ability to connect an external control panel with RJ45 interface;
- Power terminals are closed to provide protection against accidental contact. The STO jumper (safe torque off) can be used as an additional motor safety measure — while the jumper is installed, the frequency inverter output is blocked. Grounding of the power circuit is available.
