4.5.5 Typical Control Technique and Function Code Setting for the Crane System
The CS500 provides the built-in brake time sequence control function. This function
requires that an output terminal is set to "brake output"; that is, the corresponding function
codes F5-01 to F5-05 are set to 21.
In the following figure, the function codes in SFVC (F0-01 = 0) and CLVC (F0-01 = 1) are
different. You need to select the corresponding function codes based on actual wiring and
set the function codes according to the figure.
Figure 4-11 Function code setting for the crane system
The braking mechanism keeps applied when de-energized and becomes released when
energized. Because the brake needs to act mechancially, there has to be a mechanical
delay between the brake output signal of the AC drive and the braking state. The open
time and close time need to be set based on the actual mechanical delay of the brake.
Theoretically, the open time and closing time must be slightly longer than the mechanical
delay to prevent hook gliding.
4.6 Motor Parameter Setting and Automatic Tuning
4.6.1 Motor Parameter Setting
The AC drive running in vector control (F0-01 = 0 or 1) requires correct motor parameters,
which is unnecessary for the V/F control (F0-01 = 2). To achive better driving performance
and running efficiency, the AC drive must obtain the correct motor parameters.
The involved motor parameters are listed in the following table.
