E7 Basic Programming Parameters
The initialization group contains parameters associated with initial set-up of the Drive. Parameters involving the display
language, access levels, initialization and password are located in this group.
A1 Initialization
A1-00 Select Language
The setting of parameter A1-00 determines which international language the Drive will use to display non-numerical text. The
A1-00 parameter will not be changed by an Initialization of the drive (A1-03= “1110: User Initialize”, “2220: 2-Wire Initial”,
or “3330: 3-Wire Initial”).
If the Drive is accidentally set to a language unfamiliar to the operator, locating the parameter to change the operator language
can be done by performing the following:
1. Press the MENU key until the “-ADV-” MENU is shown in the upper left corner of the digital operator.
2. Press the DATA/ENTER key to enter the programming menu. The first parameter shown is A1-00 (Select Language).
3. Press the DATA/ENTER key again and use the INCREASE and DECREASE arrow keys to choose the preferred language
from the list below:
0 : English
1 : Japanese
2 : Deutsch (German)
3 : Francais (French)
4 : Italiano (Italian)
5 : Español (Spanish)
6 : Portugus (Portuguese)
A1-01 Access Level Selection
A1-01 can be used to allow access to and permission to change all Drive parameters. If the Drive is programmed for Operation
Only (A1-01= “0: Operation Only”), then only the OPERATION and the PROGRAMMING menus are accessible. Within the
PROGRAMMING menu only parameters A1-01 and A1-04 are adjustable.
Setting Description
0 English (factory default)
1 Japanese
2Deutsch
3 Francais

6Portugues
Setting Description
0OperationOnly
1UserLevel
2 Advanced Level (factory default)

Programming 3
If A1-01 is configured for Advanced Access (A1-01= “2: Advanced Level”), then all menus and all parameters are shown. If
the Access Level Selection is set to Advanced, all parameters should be adjustable unless:
1. The Drive parameters are password protected (A1-04) which will prevent access to A1-00 through A1-03 and all A2
parameters.
2. A digital input has been configured as a Program Lockout (H1-0X= 1B) is active.
3. During serial communication writing, if a parameter change is also attempted via the digital operator, a
“BUSY - WRITE PROTECTED” message will display. Parameter change will not be possible from the digital operator until
an Enter command is received via the serial communication to finish the serial writing process.
A1-03 Initialize Parameters
The Drive can be set back to one of three default states via the A1-03 parameter.
1. User Initialization – 1110: The modified Drive parameters are returned to the values selected as user settings. User settings
are stored when parameter o2-03= “1: Set Defaults”.
2. 2-Wire Initialization – 2220: The Drive parameters are returned to factory default values with digital inputs S1 and S2
configured as Forward Run and Reverse Run, respectively.
3. 3-Wire Initialization – 3330: The Drive parameters are returned to factory default values with digital inputs S1, S2, and S5
configured as Run, Stop, and Forward/Reverse respectively.
After an initialization is performed, parameter A1-03 will automatically be set back to 0.

A1-04 Password Entry
Setting Range: 0 to 9999
Factory Default: 0
If parameters A1-01 through A1-03 and all of the A2 parameters are locked (unchangeable) they can be unlocked by entering
the correct password number into A1-04.
Once the correct password number is entered and the specified parameters are unlocked, a 2-Wire or 3-Wire initialization will
reset the password to 0000.
A1-05 Select Password
Setting Range: 0 to 9999
Factory Default: 0
When the value set into A1-04 does NOT match the value set into A1-05, parameters A1-01 thru A1-03 and A2-32 cannot be
changed. All other parameters determined by A1-01 can be changed. Parameter A1-05 can be accessed by displaying
parameter A1-04, then press and hold the RESET key along with the MENU key simultaneously.
A2 User Parameters
A2-01 - A2-32 User Parameter
Setting Range: b1-01 to o3-02
Factory Default: <none>
The Drive can be programmed to select up to 32 parameters for limited-access programming. By setting the Access Level to
User Level (A1-01= “1: User Level”), only the parameters entered into parameters A2-01 through A2-32 can be accessed and
modified by the user.
Parameter A1-01 must first be set to 2 (Advanced Access Level) in order to program the A2 parameters to the desired user
parameters. Once the A2 parameters are programmed, A1-01 should be set to 1(User Access Level) to prevent the user from
changing any parameters except the A1 parameters and the parameters specified in A2-01 through A2-32.
b1 Sequence
The Sequence Group contains parameters associated with starting and stopping the Drive. Parameters involving the Run
Command, Speed Reference location, Stopping Method and Hand/Auto changeover are located in this group.
