Conforming Standards: CG follows IEC-146 & IEEE-444 for Thyristor Bridges
Features of AFM: Digital regulator ADD32 :- Suitable for precession process industry such as Steel plant environment
- Proven technology
- Fully configurable for each and every application
- 32 bit microprocessor
- Built in programmer
- Designed for high reliability and ease of maintenance
- Isolated from Power part
- Easy replacements of faulty cards
ADD32 Regulator-tot-PLC/PC Interface Software Features:
The ADD32 drive regulator can communicate directly to PLCs of following make thru soft connectivity- Rockwell – Ethernet/IP
- GE Fanuc – EGD
- Schneider Electric - Modbus TCP
and thru hard-wired signals or thru additional add-on communication modules with PLCs of other makes.
The ADD32 drive regulator can communicate directly to PC thru soft connectivity by using Drive maintenance software – ADDapt2000, that is compatible with Windows. The ADDvantage-32 based DC Drives support an IEEE 802.3 Ethernet star structured network. The ADDvantage-32 supports both 100 base FX Fiber Optic and 10/100 base UTP Copper Ethernet media. Multiple ADDvantage-32 Regulators of various Drives can be connected with multiple PLCs, HMIs and program loader PC in a single Ethernet/IP Network in Star Topology, which enables seamless communication for process control.
ADDapt2000 shall be useful for -
- Drive software upload/down load
- Drive Parameter Trending
- Develop Parameter monitor screens for on-line monitoring & troubleshooting
