Features:
- Resolver and TTL incremental encoder feedback interface
- One resolver input, one TTL encoder input and one TTL emulation output
- Two digital position-latch inputs with IP20 protection
The module installs in a supported ABB drive option slot and processes feedback used by the drive control program.
Its resolver interface supports sine/cosine feedback, while the TTL interface supports differential A/B/Z signals and encoder emulation.
