| Torque Response Time | < 5 ms (0 to 100% rated torque) |
| Bandwidth (velocity mode) | ~500 Hz |
Applicable Industries:
Packaging machines, material handling, textile machinery, plasma/laser cutting, injection molding, conveyor systems
Installation Requirements:
- Mount vertically with minimum 100 mm clearance above and below for airflow
- Use shielded cable for all signal connections
- Ground the drive chassis and motor frame to the same earth potential (< 1 Ω)
- DC bus capacitors require pre-charge circuit — do not hot-plug DC bus
Usage Notes:
- Derate current by 1% per °C above 40°C ambient temperature
- Ensure DC bus voltage does not exceed 565 V DC under any condition
- Configure STO function before enabling power — required for functional safety compliance
