Hello,
I’d like to ask for help and advice. I have an upcoming crane application where a frequency inverter G120 with CU250S and an HTL incremental encoder will be used for speed control in mode p1300=21.
The crane includes:
I would appreciate your recommendations on which parameters I should focus on or study, so I have at least some understanding.
I’m also interested to know more about parameters related to inverter fault responses, encoder fault responses as well as for the lift - hoisting drive – e.g. torque limits , i guess some braking times dealy and PID adjustment will be needed for hoisting drive.
The brake timings I plan to adjust based on the motor manufacturer's manual.
Below I'm sending parameters that I don't fully understand yet, but I know they will be needed. I extracted them from a similar crane project.
p491 = 1 , this setting is used in similar project for crane application , after encoder fault it should continue with sensorless operation , But here I'm not sure if an additional DDS dataset needs to be added in case an encoder fault occurs and the inverter should continue operating in sensorless mode. Do you have experience with this?
p1226 and p1227 , im not sure what i can adjust if i try to increase , decrease this parameters.
p1520,p1521 - torque limit upper , lower - this parameter is set by default druing motor identification?Or should be adjusted ?
p1610 - torque setpoint static , not sure what is this?
p1901:
p1901.0
p1901.1
p1901.2
On similar project for hoisting drive this 1901 parameters were used , they are some kind of selftest ?
As im using brake resistor connected on R1/R2 , so when braking resistor is used , is it necessary to set parameters p1240 and p1280 to “inhibit” [0] or to “kinetic buffering“ [2]?
As I am using a sine wave filter on the drive output, is it also necessary to set parameter p230 = 3? There is also parameter p233, but I'm not sure what to set there or if it's needed.
Parameter P1210 is set to P120=[26] , not sure here if i understant what will do after auto clearing fault
Thanks in advance for your time and effort to help
If you have experience with at least something I mentioned above, that will help.

The crane includes:
- 2 drives at the front, 2 drives at the rear,
- and one hoisting drive for lifting the material.
- Also moving carriage with lift in middle of crane with 2 motors
- an encoder,
- a brake,
- a braking resistor,
- and an output filter after the inverter output.
