This parameter indicates the velocity feed forward reference when position control is used (see section 5.15 Menu 13: Position control on page 232).
This bit indicates that the position controller has selected the velocity feed forward as a reference for the drive
Pr 1.41 to Pr 1.44 control Pr 1.49. The priority order is Pr 1.44 (highest), Pr 1.43, Pr 1.42, Pr 1.41 (lowest). If more than one parameter is active, the
highest priority takes precedence.
Pr 1.41 = 1 forces Pr 1.49 = 2 (see table in Pr 1.14 on page 35 and Pr 1.15 on page 36)
Pr 1.42 = 1 forces Pr 1.49 = 3 (always selects preset references)
Pr 1.43 = 1 forces Pr 1.49 = 4 (always selects keypad control mode)
Pr 1.44 = 1 forces Pr 1.49 = 5 (always selects precision reference)
Pr 1.45 to Pr 1.47 control Pr 1.50.
Pr 1.45 controls Pr 1.50 bit 0*
Pr 1.46 controls Pr 1.50 bit 1*
Pr 1.47 controls Pr 1.50 bit 2*
*See the description with Pr 1.14 and Pr 1.15 on page 36 for more information.
When this flag is set the preset timer for auto preset timer mode (Pr 01.15 = 9) is reset and preset 1 is selected. This can be used to start a new
sequence of reference selection by a programmable input terminal or function. When this bit is zero the preset selection will follow the timer even
when the drive is disabled.
