– Key Features
Feedback & Sensing
Dual encoder input, auxiliary encoder input, Hall sensors, tachometer, incremental encoder, absolute encoder (EnDat®, Hiperface®, BiSS® C-Mode), resolver, and 1 Vp-p Sin/Cos encoder support enable flexible sensor integration.
Command Sources
Internal generation, external analog input (±10 V), auxiliary encoder, preset index table, and CANopen command inputs provide multiple motion instruction methods.
Parameter Management
All drive and motor parameters are stored in non-volatile memory for persistent configuration across power cycles.
Protection
Comprehensive built-in safeguards include over-voltage, under-voltage, over-current, over-temperature with pre-warning, and phase-to-phase/phase-to-ground short-circuit protection.
