Introduction
Information information
Pr 11.26
0 The transmit buffers are turned on and data transmission begins immediately.
1 The transmit buffers are turned on and data transmission begins after 1ms.
The transmit buffers are turned on after an additional delay of (Pr 11.26 – 1)ms and data
2 or more
transmission begins after a further 1ms delay.
Note that the drive holds its own transmit buffers active for up to 1ms after it has transmitted data before switching to the receive mode, and so the
host should not send any data during this time.
Modbus RTU uses a silent period detection system to detect the end of a message. This silent period is either the length of time for 3.5 characters at
the present baud rate or the length of time set in Pr 11.26, whichever is the longest.

Range Regen
Update rate Background
If this parameter is zero the drive is a standard Unidrive SP 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.

Update rate Background
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.

Update rate Background
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.

Update rate Background
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.drive mode is not changed
