Issue Number: 7 www.controltechniques.com
minimum is reached. However with the second method an increasing
rate of change does not take place when adjusting any other digit other
than the least significant digit since a digit can only have one of 10
different values. Holding the Up or Down will cause an auto repeat and
roll over to more significant digits but the rate of change is unaltered. If
the maximum or minimum is exceeded when adjusting any other digit
than the least significant one, the maximum value will flash on the
display to warn the user that the maximum or minimum has been
reached. If the user releases the Up or Down key before the flashing
stops the last in range value will re-appear on the display. If the Up or
Down key is held the display will stop flashing after 3 seconds and the
maximum value will be written to the parameter.
Parameters can be set to 0 by pressing the Up and Down keys
simultaneously.
2.6 SM-Keypad Plus advanced operation
All keypads built after data code N10 have software version 4.02.00
programmed and will support 5 languages (English, French, German,
Spanish and Italian) in addition to the original capability of a user defined
parameter set. This software also gives the user access to two new
menus for SM-Keypad Plus. Menu 40 is for SM-Keypad Plus set up,
menu 41 selects commonly used parameters for quick browsing.
Keypads built prior to N10 will support one user defined extra parameter
set only.
2.6.1 Browsing filter
Pr 40.06 Browsing Filter
The user is able to define their own browsing filter using menu 41. This
allows the user to chose up to 20 parameters for quick browsing in one
vertical menu. (Menu 41 is saved using Pr 40.03).
When in browsing filter mode the first routed parameter will be Pr 41.00,
which will be called 'F00'. The next parameters are the user routed filter
parameters called 'F01' etc.
When the browsing filter has been activated the only parameters
accessible to the user are those specified in the filter. The user scrolls
through the parameters using the up and down joy pad buttons; the left
and right buttons are not used.
Pr 71.02 for the SM-Applications in slot 2 is expressed as Pr271.02.
2.6.2 'Hardware key' feature
This feature can be used to prevent unauthorised modification of the
drive parameters via the user interfaces (display or serial comms) on the
front of the drive unless the user has the mating SM-Keypad with the
correct code programmed.
Pr 40.07 Keypad security code
• To lock LCD Keypad internal menus (menus 40 and 41)
Enter code into Pr 40.07.
Exit edit mode - this saves the menu and code.
• To unlock LCD Keypad internal menus:
Enter keypad security code in Pr x.00 (e.g. Pr 40.00).
Press mode (Pr 40.00 and Pr 40.07 will return to zero).
Pr 40.09 Hardware key code
Procedure for setting through LCD keypad on RJ45(RS485) port.
• Set up drive security code in Pr 0.34 / Pr 11.30
• Set hardware key code in Pr 40.09 to the same value as the security
code (Pr 0.34 / Pr 11.30 becomes value hidden)
• Save the SM-Keypad Plus internal menu by setting Pr 40.03 to save
(Pr 40.03 will return to idle once save is complete)
• Set SM-Keypad Plus internal menu security by writing a code to
Pr 40.07 (Pr 40.09 becomes value hidden)
• Lock the drive by setting Pr 0.49 / Pr 11.44 to LOC and pressing
STOP/RESET (will return to L1)
The user will have read/write access to the drive parameters but not the
LCD keypad internal menus (Menu 40 and 41) with the specific keypad still
fitted. Any other keypad (SM-Keypad Plus or SM-Keypad without the
correct code programmed ) will provide read only access to all parameters.
Procedure for preventing user access via the RJ45(RS485) port on
the drive.
• Connect PC to RJ45 port and change Pr 11.24 to LCD (this will now
prevent access via a PC), (Timeout error will show on CTsoft, this is
normal)
• Without powering the drive off place the SM-Keypad Plus with
correct hardware key into the RJ45 port and carry out a drive
parameter save.
The user will have read/write access to the drive parameters but not the
SM-Keypad Plus internal menus (menu 40 and 41), and the comms port
will be disabled.
Procedure for resetting hardware key and comms access.
• Unlock the SM-Keypad Plus internal menu security to make Pr 40.09
visible. (See Pr 40.07)
•Zero Pr 40.09
• Unlock drive security by entering the correct code in Pr 0.34 /
Pr 11.30.
• Save the internal SM-Keypad Plus menu (see Pr 40.03 above)
• If the comms port lock is on (i.e.Pr 11.24 set to LCD) put an SM-
Keypad onto the front of the drive and turn Pr 11.24 to RTU mode
and carry out a drive save.
The user will now have read/write access to the drive parameters and
the SM-Keypad Plus internal menus (menu 40 and 41).
2.7 Parameter access level and security
The parameter access level determines whether the user has access to
menu 0 only or to all the advanced menus (menus 1 to 21) in addition to
menu 0.
The User Security determines whether the access to the user is read
only or read write.
Both the User Security and Parameter Access Level can operate
independently of each other as shown in the table below:
RW = Read / write access RO = Read only access
The default settings of the drive are Parameter Access Level L1 and
user Security Open, i.e. read / write access to Menu 0 with the advanced
menus not visible.
