Digitax ST Advanced User Guide 147
Issue Number: 1 www.controltechniques.com
If this parameter is zero the drive is a standard product. If this parameter is non-zero then the product is a derivative product. Derivatives can have
different defaults from the standard product and restrictions on the values allowed for some parameters.
The drive software version consists of three numbers xx.yy.zz. Pr 11.29 displays xx.yy and zz is displayed in Pr 11.34. Where xx specifies a change
that affects hardware compatibility, yy specifies a change that affects product documentation, and zz specifies a change that does not affect the
product documentation.
If any number other than 0 is programmed into this parameter user security is applied so that no parameters except Pr 11.44 can be adjusted with the
LED keypad. When this parameter is read via an LED keypad and security is locked it appears as zero. The security code can be modified via serial
comms etc. by setting this parameter to the required value, setting Pr 11.44 to 2 and initiating a reset by setting Pr 10.38 to 100. However security can
only be cleared via the LED keypad.
The value of this parameter is fixed at 3. This is a read only parameter.
See section 5.6 Menu 4: Torque and current control on page 68 for more details.
This parameter has two possible values (200 or 400) and indicates the voltage rating of the drive.
