inverter,s Zero speed level (dc injection braking starting frequency )

Zero speed level (dc injection braking starting frequency ).

used to set the frequency which starts DC injection breaking (the initial excitation for flux vector control) in unit of Hz

note:

the DC braking function to supply  DC current to motor and decelerate  the motor.this happens in the following two cases.DC injection braking time at start Effective for temporarily stopping and then restarting,without regenerative processing, a motor coasting  by inertia DC injection  braking time at stop.used to prevent coasting by inertia  when the motor is not completely.for the zero level (b2_01),set the frequency for beginning DC for the injection braking for deceleration.if the excitation level is lower then the minimum output frequency(E1_09),the dc injection braking will begin from the minimum output frequency.in flux vector control mode,DC injection braking becomes  the initial excitation starting frequency at the time of deceleration.in that case,braking starts from the excitation level regardless of the minimum output frequency setting.the excitation level is also used as the operating frequency for zero servo function (for flux vector control only).for the DC injection barking current (b2_ 04),set the value for the current that is output at the time of DC injection barking DC injection braking current is set as a percentage of invertor rated output current,with the rated output current taken as 100%.for the DC injection braking operating time for when the motor is stopped.

inverter,s operation selection for setting of e1-o9 or less and control input scans.

 

                             








 operation selection for setting of e1-o9 or less

used to set the method of operation when the frequency reference input is less than the minimum output frequency (e1-o9).only effective in the mode of pg vector control.
0:run at frequency reference (e1-o9 not effective).
1:stop (frequency below e1-o9).
2:run at the frequency set in e1-o9.
3:run at zero speed (frequencies below e1-o9).
note: this is the operation method when a frequency command which is below minimum frequency was input.

                                                         control input scans

used to set the responsiveness of the control input (forward/reverse and multi-function inputs ).
0:tow scans every 2 ms,used for fast responses .
1: tow scans every 5 ms (use for possible malfunction due to noise ).
note : please set the responsiveness of program input (forward/reverse,multi-function inputs).

inverter,s stopping method selection and prohibition of reverse operation .

                                               

 stopping method selection

used to set the stopping method . 0:ramp to stop . 1:coast to stop . 2:dc injection braking stop (stops faster than coast to stop . no regenerative operation) 3:coast to stop with timer run commands are disregarded during deceleration .

note :
please set the stopping method while the stopping command is input . only setting 0 and 1 can be used with flux vector control.

                                               prohibition of reverse operation

to set reverse operation. 0:reverse enable .1:reverse disable .

note :

when this command was input ,the function to set the motor,s forward operation or reverse operation will be disable . it is used in the application where reverse operation is prohibited .

inverter,s operation method selection.of inverter.

operation method selection.
used to set the input method of the operation command .
0: digital operator .
1: control circuit terminals (analog input ).
2: Memobus transmission (s1 -k2)
3: option card .
4: M emobus transmission  (for cp -717 )
note: please set where to input the operation command.when a control circuit terminal (external terminal)is set, the unit operates with 2-wire forward run/ stop and reverse run/stop control.(when the unit has been initialized for a 3-wire control or a multi function input is run, stop and forward/reverse controls .).

inverter,s user setting constant and reference selection of inverter.

user setting constant .
used to set the constant numbers that can be set/read maximum 32 .
note : effective when the access level (a1-01) is set to be 1( user program constants)
constant can not be read when access level is 4 when access level is with in the range of user program constants, the accessible constants depends on the following.

driving mode.                                                          . quick setting level can be monitored.

environment setting method....                .the constants which can be accessed set level quickly.

level method .......                                   .can only access and set the constant which set by a2-01-32

self learning method..............                .not display.
check mode ................                          .not display .


reference selection .
used to set the in put method for the frequency reference
0: digital operator.
1:control circuit terminals (analog inputs ).
2: memobus transmission (s1-k2 )
3: option card .
4: memobus transmission (for cp-717).
note: the frequency reference is input from the control circuit terminals (external terminals ),so set b1-01 to 1, please see h3 constants group for signal level.

inverter,s user setting constant . initialize . password 1 and 2 of inverter.

user setting constant.
control method selection.
0: control without PG/F
1: control with PGV/F
2: vectot control with PGs
note : the user constant is not returned to the factory setting when constants are initialized.

initialize .
constant has been initialized according to the designated method .
0 : not to initialize.
1110 : intial value set by user .
2220 : 2-wire sequential initialization (initializes the user constant to the factory setting ).
3330 :3-wire sequential initialization .
note : for details please see the section for user initialization in chapter 3.

password : 1
while password was set to a1-05 in putting password to ai- o4 is to write-protect the initialize - mode user constants .
note :user constants a1 -01 through a1 -03 and a2 -01 through a2 -32 can be displayed but not changed if the content of a1- 04 and a1-05 are not the same.

password : 2
used to set a four digit number as the password .
note : this constant is not usually displayed...it is to write - protect the initialize - mode user constants if the setting of a1 -01-03 and a2-01-32 can not be changed but only can be read. to write -protect the initialize - mode user constants,set the password in a1-05 after inputting the desired .value in a1-01 through a1-03 and a2-01 through a2-32 user constant a1-05 can be displayed. by displaying a1-04 and pressing the menu key while pressing the reset key .(a1-05 can not be displayed.whith the usual key sequences).

for digital operator display:0(English) 1.(Japanese) 2.German) 3.(french) 4.(Italian) 5.(Spanish) 6.(Portuguese)
Note: this user constant will not go initialized .it must be manually reset to the factory setting .

1:use selection parameters (effective only to access to the contant a2-01-32.
2:quick start:q
3:basic:b

note : the user constants that can be displayed and changed also depend upon the control method being used.
