Wegner Crane CFW500 series, Applications Manual, Page: 69 / 84

Parameters Description
Crane | 69
Description:
This parameter defines the percentage of the motor synchronous speed that will be the hysteresis used to
detect inverter torque limits during the execution of load hoisting/forward or lowering/reverse commands in the
crane motion application. In other words, if the motor speed is less than (hoisting/forward) or greater than
(lowering/reverse) the hysteresis value when compared to the speed reference, then the inverter torque limit
condition is detected.
NOTE!
A setting of “0.0 %” disables the fault.
P1029 – Inverter in Torque Limit Fault (F775) Delay Time
Adjustable
0.00 to 650.00 s
Factory Setting:
0.75 s
Range:
Proprieties:
Access groups via HMI:
SPLC .....
Description:
This parameter defines a delay time after the inverter in torque limit condition has been detected, before the fault
“F775: Inverter in Torque Limit”, is generated.
3.17 IMPROPER OPERATION
This parameter group allows to the user to adjust the conditions to supervise the use of the crane motion
verifying whether it is being operated properly.
P1058 – Inverter in Torque Limit Fault (F775) Delay Time
Adjustable
0 to 10
Factory Setting:
3
Range:
Proprieties:
Access groups via HMI: SPLC .....
Description:
This parameter defines the number of consecutive alarms during the period programmed in P1059 to generate
the fault “F777: Improper Operation”. The practical result of this fault is not allowing the user to continue the
crane motion operation in case of consecutive alarm messages.
NOTE!
A setting of “0” disables the fault.
P1059 – Period of Time for Improper Operation Fault (F777)
Adjustable
0 to 65000 s
Factory Setting:
120 s
Range:
Proprieties:
Access groups via HMI:
SPLC .....
Description:
This parameter defines the period of time during which the number of consecutive alarms programmed in
P1058 must occur, in order to generate the fault “F777: Improper Operation”.
