and H1.04 at this time, convert H1.03 and H1.04 into decimal, and the total pulse is P2.
=H1.03*65535+H1.04. Then H1.05 = (P2-P1) / S.
◆ Please calculate the maximum speed of the hoisting mechanism corresponding to the maximum
frequency P0.11 according to the machine and set it in H1.11, the unit is cm/s. H1.12 =
H1.11/P1.01, H1.13 = H1.11/P1.03.
◆ Position correction method: Set the position correction position. If the position is 100cm, the pulse
amount at this time is P3=100*H1.05. If P3 is less than 65535, set the data of P3 to H1.02. H1.01
is set to 0; if P3 is greater than 65535, then P3/65535 is calculated, the integer part is set to H1.01,
the remainder is set to H1.02, for example, P3=1234567, and the integer part of 1234567/65535 is
18 , the remainder H1.02=1234567-18*65535=54937. When setting, you need to convert to
hexadecimal, then H1.01=12, H1.02=D699.
Use an X terminal as the position correction terminal and set this terminal function to 33. If X1 is used,
set P5.00=33. Run the inverter to the position of the calibration position. At this time, close the X1
terminal and reset the position to 100cm.
◆ H1.07 and H1.08 are the position forward maximum position and reverse maximum position. If
these two values are exceeded, the inverter will judge the position is disordered and need to
re-correct the position.
◆ H1.09 and H1.10 are the forward stop position and the reverse stop position. If they reach the
position, they will not run.
5.9 Parameters copy function for batch debugging
After finished debugging parameters of one inverter, you can use the debug parameter copy function
to copy the
parameters to another inverter.
Parameters copy detailed steps as follows:
● Mount keyboard A to a inverter A has finished debugging ;
● Set parameters Pb.23 = 1 for parameter upload;
● Mount keyboard A to one another inverter B haven't debugging;
● If the motor and inverter are same, set Pb.23=3 to download parameters;
● If the motor or inverter not same, but signal wiring are same, please auto tuning at firs then set
Pb.23 = 2 for download without motor parameters，then set P0.06=0 and motor parameters for
parameter self-learning. Restore P0.06 to the set value after self-learning;
● Then power off completely re-commissioning is completed, must be completely powered off (the
inverter keypad no any display) then power on.
5.10 Method of operating a inverter without a motor
The crane dedicated inverter has built-in current and torque detection and protection parameters. If the
inverter is operated without motor under the default parameters, it will alarm.If you need to run the
inverter without a motor, please set the following parameters to 0: P8.04, H0.02, H0.03, H0.05, H0.06.
