5.2.4 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 2 (Lifting in closed-loop vector control)
first, set P11.08 to 0x000 to disable underload protection, and set P90.14 and P90.15 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 P25.02 to 75, and the macro has been set by default. In
addition, set P90.31 to 1. Since the closed-loop mode is used, the brake current monitoring
function is automatically enabled after the setting, and you can set P90.34 to set whether the
reference speed is used if the brake status is incorrect. If there is no brake feedback signal, set
P90.31 to 0 to prevent the misreporting of a brake feedback fault.
In closed-loop mode, brake slip verifying is enabled by default. If you need to check the running
status of the VFD without a brake, set P93.01 to 0 to disable brake slip verifying.
During onsite commissioning, if the VFD terminal signal upward/downward running command is
inconsistent with the hook lifting/lowering, swap any two phase wires of VFD output terminals U,
V, and W.
If PLC control is used, speed signal and other input and output signal functions need to be
adjusted according to the actual control logic.
This macro can meet the requirements of most tower crane lifting application cases, and the
performance parameters have been optimized and do not need to be adjusted in most cases. If
an exception occurs, see the function parameter chapter for adjustment or contact the technical
support.
