VB Cur Thresh
Variable Boost Current Threshold
Sets the P1548 [VB Current Rate] trigger level for the variable boost voltage function.
The trigger is not active until P1538 [VB Time] time has expired following a drive start.
P1535 [VB Config] Bit 2 “Rising Edge” = 0:
The value of [VB Current Rate] must first pass through [VB Cur Thresh] + P1549 [VB
Current Hyst] then [VB Cur Thresh] in order to cause a boost voltage trigger event.
P1535 [VB Config] Bit 2 “Rising Edge” = 1:
The value of P1548 [VB Current Rate] must first pass through [VB Cur Thresh] - P1549
[VB Current Hyst] then [VB Cur Thresh] in order to cause a boost voltage trigger event.
Default:
Min/Max:

VB Rate Lag Freq
Variable Boost Rate Lag Frequency
Sets the lag (cutoff) frequency of the current magnitude low pass filter.
The output of this filter is displayed in P1548 [VB Current Rate].

Important: After the Spindle Orient group is set up for an application, any subsequent
changes to parameter settings will require a drive reset for the changes to take affect.

SO Config
Spindle Orientation Configuration
RW 16-bit
Integer
Configures the options for the Spindle Orientation function.
Function requires P35 [Motor Ctrl Mode] is set to option 3 “Induction FV,” 6 “PM FV,” or 10 “IPM FV.” P125 [Pri Vel Fdbk Sel] and P135 [Psn Fdbk Sel] must also be set
up accordingly.
Bit 0 “Home DI” – Selects the type of Homing signal (Marker Pulse vs. Digital Input Switch). 1 = Home signal. 0 = Z Channel.
Bit 1 “Home DI Inv” – Rising/Falling Edge of Homing Input.
Bit 2 “Recap Hm Psnv” – Re-capture Home Position. Allows the drive to find Home after a power or drive reset. Typically set to 1 “Enabled.”
Bit 3 “ShortestPath” – Allow direction reversal to obtain shortest distance traveled.
Bit 4 “Scale Invert” – Inverts the calculation for the user-defined units value. This improves resolution as the value of P1587 [SO Cnts per Rvls] increases.
