4. Function Description
Parameter P-01 must be set to 1 or 2 for the Decel Position function to operate. When P-01 = 0, the V7 functions as
standard.
When position speed mode is disabled (P-02 = 0), the V7 functions according to Figure 2. When the run command is
removed, the current frequency reference is sampled and the decel time calculated.
With position speed mode enabled (P-02 = 1), the V7 functions according to Figure 3. When the Position Speed multi-
function input is closed, the current frequency reference is sampled and the decel time calculated. The inverter
decelerates to the P-04 speed using the calculated decel rate. When the run command is removed, the drive will stop
using the normal active decel rate.
When the Ink Dip Select multi-function input is closed, the drive changes direction and runs at the Ink Dip Reference
(P-07). If P-01 = 2, the drive deceleration time during Ink Dip is Deceleration time 2 (n022). If P-01 = 1, the drive
deceleration time during Ink Dip is either the programmed decel time run command is closed) or the calculated decel
positioning time (run command removed). The Ink Dip multi-function input overwrites the Position Speed multi-function
input.

Note: If reverse operation is disabled (n006 = 1), the drive has a forward run command and the Ink Dip Select multi-
function input is closed, the drive will will run at the P-07 reference but it will continue to run in the forward direction.
