3.Can the FR-A820-1.5K-1 directly replace the previous model FR-A720-1.5K? What core parameters need to be adjusted during replacement?

Parameter Category	Adjustment Points
Control Mode	Confirm vector/sensorless vector mode; A820 adds PM sensorless vector mode, switch as required
Motor Parameters	Re-enter motor rated power, current, speed, etc., and perform auto-tuning
I/O Configuration	Verify terminal functions (e.g., multi-speed, forward/reverse rotation); some terminal definitions of A820 are optimized
Frequency/Torque	Set upper frequency limit (max. 400Hz for A820 sensorless vector mode), acceleration/deceleration time, torque boost value
Protection Parameters	Adjust overcurrent, overload, overheat protection thresholds to adapt to A820’s new protection logic
Communication Parameters	If using fieldbus, confirm expansion module compatibility and reconfigure communication address/baud rate
