Often indicates a Hall sensor error (Check H parameter or ensure sensors are connected properly).
Set to ON (Closed loop) for torque/speed precision, OFF (Open loop) if required. P (Waveform): Keep this function disabled (OFF).

正常。在常温下，长时间工作外壳达到 90℃ 不会对性能产生影响。
The is often required to program specialized parameters, such as motor pole count and torque parameters, tailored to specific motor needs. 4. Troubleshooting and Protection Features
The driver can be configured using the ZM-BL01 Handheld Intelligent Debugger or specialized PC software. Key configurable parameters include: Often indicates a Hall sensor error (Check H
Soft-start acceleration ramp. Higher values decrease mechanical shock on high-inertia loads. Hall Sensor Verification

: Features a double closed-loop design (current and speed) for high torque at low speeds and stable overall operation. Control Terminals and Port Descriptions
If the manual is truly extinct (common for 1980s–1990s gear), don’t despair:
: Commonly caused by setting Parameter H (Hall Sensor) to ON when the physical Hall harness is disconnected or broken. Check sensor wiring or switch Parameter H to OFF .
