APPLICATIONS
Variable Boost
1548 VB Current Rate
Variable Boost Current Rate
Output current rate of change.
Default:
Min/Max:
0.0
–/+1000.0
RO Real
1549 VB Current Hyst
Variable Boost Current Hysteresis
Sets the hysteresis level around P1550 [VB Cur Thresh] for the variable boost voltage
function.
Default:
Min/Max:
0.0
–/+100.0
RW Real
1550 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:
–25.0
–/+1000.0
RW Real
1551 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].

APPLICATIONS
Spindle Orient
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.
1580 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.
