Danfoss VLT series Programming Guide

fo Forward only:
0: Forward and backward movement is processed.
1: Only forward movement is processed.
If the movement of the reference input (master axis) is going backwards, the last forward directed position is kept. The
further forward movement is started when the last seen forward position of the reference input is reached again. If the
guide value goes back more than half of the range, the servo drive goes into fault state.
vel Use velocity:
0: Servo drive calculates the velocity from position dierences internally.
1: Servo drive uses Velocity guide value object (0x2064).
ce Command error:
0: Plausibility check disabled.
1: Plausibility check enable.
7.8.4 Parameter: Guide Value Scaling Factor (0x3808)
The servo drive also supports scaling of the guide value. The scaling factor consists of a numerator and a denominator.
The value 0x0000 0000 must be reserved and not used for the numerator and the denominator objects. To be able to
change both values simultaneously, a writing order is dened. The activation of the new factor is done after the writing of
the numerator. This means to change both values at the same time, the denominator must be written rst and the
numerator afterwards. It is also possible to only change the numerator by writing a new value (the denominator stays the
same). The numerator and denominator accept negative values. The division of 2 negative values results in a positive value.
The Position guide value is multiplied by the quotient of numerator and denominator.
Guide value scaled = (Guide value x Scaling value) + Guide value oset
