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.
This parameter defines the drive mode. If this parameter is changed from the current drive mode, Pr x.00 is set to 1253, 1254, 1255 or 1256, and then
the drive is reset the drive mode is changed to the mode defined by this parameter. After the mode change the default settings of all parameters will
be set according to drive mode. The drive mode will not be changed if the drive is running. If the parameter value is changed and a reset is initiated,
but Pr x.00 is not equal to 1253, 1254, 1255 or 1256, or the drive is running, this parameter is set back to the value for the current drive mode and the
drive mode is not changed.
This parameter indicates the continuous current rating of the drive for Heavy Duty operation. See section 5.5 Menu 4: Torque and current control on
page 80 for more details.
This parameter has four possible values (200, 400, 575, 690) and indicates the voltage rating of the drive.
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.
