For more information, please see anu 12-pulse opera­ tion. All parameters can accessed by the serial communication IEC 61131 adaptive programming. Functions basic firmware Different speed ramp function Speed control Torque control Armature current control Field current control Automatic field weakening E-stop function according Profibus standard Dual field control Mechanical brake control DC breaker control Interface for fieldbus and module bus Programmable digital and analogue outputs Master-Follower bus 16 blocks Adaptive Program Interface for IEC 61131 programming 12-pulse function parallel, serial, sequential 3-phase field exciter operation Converter protection (temperature, voltage,. The firmware interface for several fieldbuses and mod­ ule bus included. are existing. Quasi 12-pulse Master-Follower configuration The converters are fed by a 12-pulse transformer with separated secondary windings whose phase positions differ by 30°el.DCS800 firmware DCS800 basic firmware DCS800 firmware includes the basic function speed control, armature current, field current and motor volt­ age.

The design drive logic enables drive reaction de­ fined Profibus standard but can also configured to adapt classic command structures. quasi 12-pulse Typical configuration for high power drives connected in 12-pulse parallel, serial sequential application 12-pulse systems are used for reduced line harmonics, reduced motor noise level, enlarged output current or voltage converter system. Five macros are pre-defined and two user macros can be configured the customer. This configuration delivers the same advantages concerning harmonics the network a standard 12- pulse application (see next item), but T-reac- tor needed. It possible connect two 12-pulse systems con­ verters, T-reactor and motor) to one 12-pulse transformer.)

The flexible design for command location enables field bus control master-follower control control from hardware signals well mixed structure.
