Performance Parameters The drive extends the S200 series performance to ultra-high power levels. The 800 Hz velocity loop bandwidth is maintained for responsive control. The current loop bandwidth of 3-5 kHz ensures smooth torque delivery at 85A levels. Position loop update rate is 500 microseconds. The drive includes advanced features such as adaptive filtering, vibration suppression, and sophisticated thermal modeling. Current regulation maintains 1% accuracy across the full operating range. The drive supports master-slave configurations for multi-motor applications.
