00040: VELOCITY FEEDBACK VALUE
The velocity feedback value is transferred from the drive to the control unit in order to allow the
control unit to periodically display the velocity.

00041: HOMING VELOCITY
The homing velocity is used during the procedure command 'drive controlled homing' (IDN 148) when
activated. The drive performs its own homing control.

00043: VELOCITY POLARITY PARAMETER
This parameter is used to switch polarities of velocity data for specific applications. Polarities are not
switched internally but externally (on the input and output) of a closed loop system. The motor shaft
turns clockwise when there is a positive velocity command difference and no inversion is
programmed (see Figure 6.2).
Bit supported by drive:
BIT NUMBER DESCRIPTION
Bit 0:
Velocity command value
= 0 - non-inverted
= 1 - inverted
Bit 1:
Reserved
Bit 2:
Velocity feedback value
= 0 - non-inverted
= 1 - inverted
