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 27 and Pr 1.15 on page 28)
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 28 for more information.

when the drive is disabled.
