1. Tracker parameters These parameters are directly important for Nano positioner Parameters are factory set according to used actuator motor Do not change values unless you are sure what you are doing Max and min range limits the moving of the motor at positioner level These settings should be the same as those on controller tab see chapter 20 I motor limitation is maximum permited current in positioner Do not set greater than 5 Amps hardware limit U I measuring factors are measuring calibration factors for voltage and current measurement in positioner We do not encourage you to change these values Rest timeout position A B When RS485 communication fails due to any reason each positioner tracker can go to some predefined rest position by itself and so set panels to the best position for catching the Sun as fixed panels until communication is repaired Timeout can be set in seconds 0 disabled feature Modbus timeout is similar like Rest timeout but it just indicate communication failure by turning orange LED on front panel of positioner Nano Status can not be seen on the web if communication fails Reference timeout means how long motor is going from totally extended position to totally closed position This is maximum permited time for motor to go to the reference If this time is exceed reference error is set in tracker status i e free motor 6 Sigma user manual_rev1 25 Manual mode2.
