FAQ
What pulse command formats are supported by this low-power digital drive?
The unit natively supports three primary pulse input modes: Pulse + Direction (PULSE/DIR), CW/CCW double pulse, and A/B orthogonal (90° phase difference) pulse. It handles differential line driver input frequencies up to 500 kHz and open-collector single-ended inputs up to 200 kHz, allowing direct interface with standard PLCs, motion controllers, and CNC systems.
What types of motor encoder feedback can be paired with the system?
The drive is engineered to interface with multiple feedback types, including 17-bit magnetic, 23-bit optical multi-turn absolute encoders, and standard wire-saving incremental encoders. For absolute feedback systems, the drive stores position data even during power outages, eliminating the need for mechanical homing routines upon startup.
How is anti-interference handled in noisy industrial environments?
Built on Tonghang's proven dual-board hardware topology, the power stage and signal processing circuits are physically isolated. Additionally, the six digital inputs (DI1–DI6) are optically coupled (12–24 VDC), and the internal feedback loop includes adaptive digital notch filters to suppress mechanical resonance and high-frequency electrical noise.
Can the drive operate using standard single-phase residential or light-industrial power?
Yes. The power supply stage is designed for single-phase 220 VAC (tolerance range: −15% to +10% at 50/60 Hz), making it fully compatible with standard single-phase workshop grids and exported automated equipment without requiring step-down transformers.
How do I adjust parameters and run commissioning?
Parameters can be configured via the built-in LED operator keypad on the drive's front panel or connected to a PC via the standard RS-485 communication port (Modbus RTU protocol). Tonghang provides dedicated PC tuning software for real-time oscilloscope monitoring, inertia auto-tuning, and parameter backup/restore.
