Parameters Description
Crane | 47
P0235 – AI1 Filter
Adjustable
0.00 to 16.00 s
Factory Setting: 0.25 s
Range:
Proprieties:
Access groups via HMI:
I/O
Description:
This parameters configure the 1
st
order filter time constant that will be applied to the analog input AI1.
NOTE!
Refer to the CFW500 programming manual for more information on the analog inputs parameters.
Some parameter options have been removed from the configuration wizard.
3.11 LIGHTWEIGHT MODE
This parameter group allows the user to adjust the lightweight mode operation conditions.
Lightweight is an operation status of the crane in which the motor current is monitored after a certain speed, in
order to determine whether it is at a low value, which would indicate lightweight. This allows an increase to the
control speed reference, therefore expediting the operation of the crane.
NOTE!
While in lightweight operation mode, the motor speed reference will be the maximum value
programmed in parameter P0134.
3.11.1 Vertical
P1037 – Hoisting Current Threshold for Lightweight Detection
P1038 – Lowering Current Threshold for Lightweight Detection
Adjustable
0.0 to 200.0 A
Factory Setting: P1037 = 10.0 A
Range:
P1038 = 7.0 A
Proprieties:
Access groups via HMI:
SPLC
Description:
These parameters configure the motor current threshold for lightweight detection with hoisting (P1037) or
lowering (P1038) commands. In other words, when the actual motor current is below the adjusted value, this
indicates that it is with lightweight.
P1039 – Speed Threshold for Lightweight Detection Enabling
Adjustable
0.0 to 500.0 Hz
Factory Setting: 0.0 Hz
Range:
Proprieties:
Access groups via HMI:
SPLC
Description:
This parameter configures the speed threshold for lightweight detection. In other words, when the actual motor
speed is higher than or equal to the reference value, it enables the lightweight detection through the motor
current monitoring.
NOTE!
A setting of “0.0 Hz” disables the lightweight detection.
