This bit can be used to enable latches on the run forward, run reverse and run inputs to allow the drive to be controlled from momentary inputs. Also
see Pr 6.04 on page 89 and Pr 6.30, Pr 6.32 and Pr 6.34 on page 95.

Pr 6.42 and Pr 6.43 provide a method of controlling the sequencer inputs and other functions directly from a single control word. If Pr 6.43 = OFF the
control word has no effect, if Pr 6.43 = On the control word is enabled. Each bit of the control word corresponds to a sequencing bit or function as
shown below.

Bits 0 to 7 & 9: sequencing control
When the control word is enabled (Pr 6.43 = On), and the Auto/manual bit (bit7) is also set to one (Pr 6.42), bits 0 to 6 of the control word become
active. A hardware enable must also be active (Pr 6.29 = On). The equivalent parameters are not modified by these bits, but become inactive when
the equivalent bits in the control word are active. When the bits are active they replace the functions of the equivalent parameters. For example, if
Pr 6.43 = On and bit 7 of Pr 6.42 = On the drive enable is no longer controlled by Pr 6.15, but by bit 0 of the control word. If either Pr 6.43 = OFF, or
bit 7 of Pr 6.42 = OFF, the drive enable is controlled by Pr 6.15.
Bit 8: Analog/preset reference
When the control word is enabled (Pr 6.43) bit 8 of the control word becomes active. (Bit 7 of the control word has no effect on this function.) The state
of bit 8 is written to Pr 1.42. With default drive settings this selects analog reference 1 (bit 8 = 0) or preset reference 1 (bit 8 = 1). If any other drive
parameters are routed to Pr 1.42 the value of Pr 1.42 is undefined.
