To enter this code you would maneuver to #00.00 and enter 149.&nbsp;&nbsp; Once this security code is entered, you will be able to maneuver throughout the Unidrive menu structure freely to view parameters.<\/p>\n<p>After a security code is entered, it will remain in effect until power is removed from the drive or if you wish to re-establish this security, you can set&nbsp; #XX.00 to 2000.&nbsp; (where&nbsp; XX means&nbsp; \u201cany menu\u201d&nbsp; )<\/p>\n<p>The User Security Code parameter is #11.30.&nbsp; The \u201cas shipped\u201d value in this parameter is 149.<\/p>\n<p>For more info you can check our webpage <a href=\"https:\/\/www.mroelectric.com\/control-techniques\/unidrive\/1\">here<\/a>, or email <a href=\"mailto:sales@mroelectric.com\">sales@mroelectric.com<\/a> or call <a href=\"tel:1-800-691-8511\">1-800-691-8511<\/a>.<\/p>\n<p>If you find that you cannot change R\/W (Read\/Write) parameters (including those in Menu 0), someone has most likely assigned their own security code.<\/p>\n<p><strong>User Security Code Assignment<\/strong><\/p>\n<p>User\u2019s can assign their own 3 digit security code within the range of 1-255 by placing it into #11.30 (writing over the 149) and performing a STORE.1 Note that this does not eliminate or change the &#8220;Normal security&#8221; code number \u2013 149.<\/p>\n<p>From this point forth, access to parameters will require that code to be placed into #XX.00.&nbsp; At this point you only have access to Menu O. After this code is entered, you must still enter the normal access code (149) to gain access beyond Menu 0 parameters ( full access).<\/p>\n<p>These security methods do not affect serial communications.&nbsp; Security affects only access to parameters through the keypad on the front of the Drive.<\/p>\n<p><strong>Forgotten Security Codes<\/strong><\/p>\n<p>People often forget their security codes.&nbsp;&nbsp; A User assigned security code is not visible at #11.30 via the serial port (you would still see 149).&nbsp; To retrieve the forgotten security code,&nbsp; you must go in through the \u201cback door\u201d .<\/p>\n<p><strong>\u201cThe Back Door\u201d<\/strong><\/p>\n<p>To obtain the forgotten security code, you can DEPRESS and HOLD the MODE key, LEFT ARROW key and either UP or DOWN Arrow key then APPLY POWER to the drive.&nbsp;&nbsp; The User security code number should appear on the data display at #00.00. Normally, the drive displays the contents of parameter #0.10 upon application of power therefore the User security code may not immediately appear.&nbsp; You must use maneuver to #00.00 to see the forgotten security code then enter it (hit the mode button twice).<\/p>\n<p><strong>Security Bypass&nbsp; <\/strong><\/p>\n<p>During initial start-up of the drive, having to enter the security code after each power-up can become a nuisance and slow down the start-up process.&nbsp;&nbsp; To bypass or eliminate the need to enter a security code, one can accomplish this by placing a 0 into parameter #11.30 and performing a Store.<br \/>\nIf this bypass is done to speed up the start-up process, you should remember to re-assign the 149 default to #11.30 (and Store) before leaving the job site. Otherwise, the drive will have no parameter access security.<br \/>\nNote: Defaulting the drive parameters (using 1244 or 1254) does not reset the User security code.&nbsp; A previously assigned code by the User will remain in effect even after defaulting parameters.<\/p>\n<p><strong>Additional information&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <\/strong><\/p>\n<p>Parameter 0.49 Security Status<br \/>\nCoding:&nbsp; RO, U Range:&nbsp; 0 to 1000<br \/>\nThis parameter indicates the current status of the drive parameter security system. Each digit indicates a particular aspect of security as follows:-<\/p>\n<p>Units digit:&nbsp; 0 = Standard security has been unlocked&nbsp;&nbsp;&nbsp; 1 = Standard security is still set<\/p>\n<p>Tens digit:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 0 = User security has been unlocked or is not active&nbsp;&nbsp;&nbsp; 1 = User security is active preventing RW access<\/p>\n<p>Hundreds digit: 1 = Parameter 11.30 not equal to 149*<\/p>\n<p>Thousands digit: 1 = Parameter 11.30 equal to zero*<\/p>\n<p>* The value of 11.30 is the last value written by the user. Parameter 11.30 always appears as 149 when first accessed by the keypad to hide the real value last written by the user. If 11.30=149 then user security is cleared. If 11.30=0 then user security and security preventing access outside menu 0 is cleared.<\/p>\n<p>Note: &#8211; In contrast to all the other parameters in menu 0, this parameter does not exist in any other menu.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>For some new User\u2019s of Unidrives, the parameter security system is sometimes found to be a rather mysterious subject.&nbsp; This article will attempt to unveil those mysteries with some help to explain the Control Techniques Unidrive Security Code Basics.
