5.6.4 Points for attention
If you only want to check whether the VFD runs properly, set P90.00=0(Common mode).
If you perform empty-load commissioning, set P90.00 to 9 (Lifting in space voltage vector control),
set P11.08 to 0x000 to disable underload protection, and set P90.12 and P90.13 to 0 to prevent
the torque verification fault reporting caused by empty load. In addition, if no external braking
resistor is connected, you need to increase the ACC/DEC time to prevent the bus overvoltage
fault reporting caused by too fast stop.
If there is a brake feedback signal, set P05.06 to 75, and the macro has been set by default. In
addition, set P90.31 to 1. If there is no brake feedback signal, set P90.31 to 0 to prevent the
misreporting of a brake feedback fault.
During onsite commissioning, if the VFD terminal signal upward/downward running command is
inconsistent with the load lifting/lowering direction, adjust any two phase sequences of VFD
output terminals U, V, and W.
