cable from damage in short-circuit situations. It will protect the surrounding devices when the internal of the inverter is short circuited.
3.3.2 Protecting the motor and motor cables
The inverter protects the motor and motor cable in a short-circuit situation when the motor cable is dimensioned according to the rated current of the inverter. No additional protection devices are needed.
3.3.3 Implementing a bypass connection
It is necessary to set power frequency and variable frequency conversion circuits for the assurance of continuous normal work of the inverter if faults occur in some significant situations.
In some special situations, for example, if it is only used in soft start, the inverter can be conversed into power frequency running after starting and some corresponding bypass should be added.
If frequent shifting is required, employ mechanically connected switches or contactors to ensure that the motor terminals are not connected to the AC power line and inverter output terminals simultaneously.

4.2 Keypad displaying
The keypad displaying state of UMI-B1 UL series inverters is divided into stopping state parameter, running state parameter, function code parameter editing state and fault
23
UMI-B1 UL Series Inverter Keypad operation procedure alarm state and so on.
4.2.1 Displayed state of stopping parameter
When the inverter is in the stopping state, the keypad will display stopping parameters which is shown in Figure 4-2.
In the stopping state, various kinds of parameters can be displayed. Select the parameters to be displayed or not by P07.07. See the instructions of P07.07 for the detailed definition of each bit.
In the stopping state, there are 14 stopping parameters can be selected to be displayed or not. They are: set frequency, bus voltage, input terminals state, output terminals state, PID given, PID feedback, torque set value, AI1, AI2, AI3, HDI, PLC and the current stage of multi-step speeds, pulse counting value, length value. P07.07 can select the parameter to be displayed or not by bit and 》/SHIFT can shift the parameters from left to right, QUICK/JOG (P07.02=2) can shift the parameters from right to left.
4.1.2 Displayed state of running parameters
After the inverter receives valid running commands, the inverter will enter into the running state and the keypad will display the running parameters. RUN/TUNE LED on the keypad is on, while the FWD/REV is determined by the current running direction which is shown in Figure 4-2.
In the running state, there are 24 parameters can be selected to be displayed or not. They are: running frequency, set frequency, bus voltage, output voltage, output torque, PID given, PID feedback, input terminals state, output terminals state, torque set value, length value, PLC and the current stage of multi-step speeds, pulse counting value, AI1, AI2, AI3, HDI, percentage of motor overload, percentage of inverter overload, ramp given value, linear speed, AC input current. P07.05 and P07.06 can select the parameter to be displayed or not by bit and 》/SHIFT can shift the parameters from left to right, QUICK/JOG (P07.02=2) can shift the parameters from right to left.
4.1.3 Displayed state of fault
If the inverter detects the fault signal, it will enter into the fault pre-alarm displaying state. The keypad will display the fault code by flicking. The TRIP LED on the keypad is on, and the fault reset can be operated by the STOP/RST on the keypad, control terminals or communication commands.
4.1.4 Displayed state of function codes editing
In the state of stopping, running or fault, press PRG/ESC to enter into the editing state (if there is a password, see P07.00 ).The editing state is displayed on two classes of menu, and the order is: function code group/function code number→function code parameter, press DATA/ENT into the displayed state of function parameter. On this state, press DATA/ENT to save the parameters or press PRG/ESC to escape.

Operate the inverter via operation panel. See the detailed structure description of function codes in the brief diagram of function codes.
4.3.1 How to modify the function codes of the inverter
The inverter has three levels menu, which are:
1. Group number of function code (first-level menu)
2. Tab of function code (second-level menu)
3. Set value of function code (third-level menu) Remarks: Press both the PRG/ESC and the DATA/ENT can return to the second-level
menu from the third-level menu. The difference is: pressing DATA/ENT will save the set parameters into the control panel, and then return to the second-level menu with shifting to the next function code automatically; while pressing PRG/ESC will directly return to the second-level menu without saving the parameters, and keep staying at the current function code.
Under the third-level menu, if the parameter has no flickering bit, it means the function code cannot be modified. The possible reasons could be:
1) This function code is not modifiable parameter, such as actual detected parameter, operation records and so on;
2) This function code is not modifiable in running state, but modifiable in stop state. Example: Set function code P00.01 from 0 to 1.

4.3.2 How to set the password of the inverter
UMI-B1 UL series inverters provide password protection function to users. Set P7.00 to gain the password and the password protection becomes valid instantly after quitting from the function code editing state. Press PRG/ESC again to the function code editing state, "0.0.0.0.0" will be displayed. Unless using the correct password, the operators cannot enter it.
Set P7.00 to 0 to cancel password protection function.
The password protection becomes effective instantly after retreating from the function code editing state. Press PRG/ESC again to the function code editing state, "0.0.0.0.0" will be displayed. Unless using the correct password, the operators cannot enter it.

5 Function parameters
The function parameters of UMI-B1 UL series inverters have been divided into 30 groups (P00–P29) according to the function, of which P18–P28 are reserved. Each function group contains certain function codes applying 3-level menus. For example, "P08.08" means the eighth function code in the P8 group function, P29 group is factory reserved, and users are forbidden to access these parameters.
For the convenience of function codes setting, the function group number corresponds to the first level menu, the function code corresponds to the second level menu and the function code corresponds to the third level menu.
