Version 4.6

Linear Belt Actuators
- Added Linear Belt Actuator with all sizing considerations including:
  - Belt Max Tensile Load
  - Cart Mass
  - Mass Distance from Cart
  - Max Load Limit Moment
  - Load Max Limit
  - Force vs Speed performance chart
Added Mechanisms in Parallel (n>1) support for
- Linear Belt Actuator
- Conveyor
Spooler Hanging Load
- The Winder Spooler (aka Winch) is extended with a Hanging Load.
- A dynamic model, considering each layer wrap of material and the changing hanging load of material.
- The Spooler Hanging Load is available for both the Winder Center & Winder Surface Driven mechanisms.
Sequence form
- When the Rated profile is displayed, the rated profile is shaded in the "margin" area underneath. Eg. If the Motor Peak Torque Margin = 10%, then the motor Tmax rated profile is drawn with a shaded region 90-100% of Tmax. This helps users see how close the application profiles are to the user specified margin.
- When a Winder Spooler, now display the Spooler as a second dynamic image when the chart crosshairs are selected
- Chart Profiles
  - Added Bleeder/Chopper Current Profile to Sequence chart
  - Added Inverter Output Frequency [fHz] profile to Sequence chart
  - Changed Ixt legend display to Ixt0, Ixt1, Ixt2 and same for Pxt0, Pxt1, Pxt2
  - Motor [Vz] profile
    - Now also draw the actual [Vz] profile, which is helpful to see if the Motor.Vz > Drive.Vz0, as well as helpful to isolate if/when Motor.Vz > Drive.Vz during Backup Power Mode
- Import Sequence
  - Added Scale Factor drop down lists (1 or -1) for the Thrust and Torque/Force vector columns, providing the option to invert all values in each column when ScaleFactor = -1
  - When imporing a Sequence, now when the number of segments exceeds the maximum allowed, the source data is "down sampled" by taking every nth segment to fall under the allowed maximum
  - When importing an Import Trace, the maximum samples allowed is 2000. When the source data exceeds the maximum allowed, the source data is "down sampled" by taking every nth segment to fall under the allowed maximum
- When opening KB Sequence, no longer use MsgBox, instead display at top of the form "Kinetic Buffer: All sequence edit functions disabled"
- When opening APM Sequence defined by another PG, no longer use MsgBox, instead display at top of the form "Sequence cannot be changed because it is defined by PGx. All edit functions disabled."
Added Profile Type Sinusoidal² and Move Rules 1/5 & 1/10
- Added new profile type "Sinusoidal²
- Added 1/5 & 1/10 motion rules for all profile types
  - The 1/2 & 1/3 rule buttons are now changed to a drop-down list to accommodate all rules.
  - The 1/5 and 1/10 rules are especially helpful in applications where the move is defined as Time/Distance and the max velocity is calculated while maintaining the motion rule.
Conveyor Mechanism
- Added support for multiple mechanisms in parallel
- Added inputs to align with new Linear Belt Actuator mechanism
  - Cart Mass
  - Mass Distance From Cart
  - Max Load Limit
  - Moment Load Max Limit
- Added Force vs Speed performance chart
Ball Screw Mechanism
- When Screw is rotating and the Nut is moving linearly, now the screw output force is transmitted through the mechanism as an Axial force as an Axial Load on the gearbox output bearing. This is helpful in sizing gearboxes in hexapods with electromechanical linear actuators/ ball screws. The axial forces of the ball screws are supported by the gearbox bearings.
Rack & Pinions
- Added Stober Rack & Pinion Sizing Rules
- Added [P_Typ1] field in RacksPinionsFeedForce table, which adds support for the Pinion Input Type [P_Typ1] as part of the combination variables that determines the Rack & Pinion FMax.
Rack & Gearbox Pinion Mechanism form
- Under the Limits tab, now display Gearbox Pinion Nominal Force, and Rack & Pinion Max Force and Max-Stop Force

- Add drop down list to view only the "Gearbox" or "Rack & Pinion" as well as the complete combined product "Rack & Gearbox Pinion"
Motor Linear Actuator performance
- Add drop down list to view only the "Motor" or "Linear Actuator" as well as the complete combined product "Motor Linear Actuator"
Position Based Load
- Added Thrust and Torque scale factors
Motor Model
- Motor I2t Model Low-Speed De-rating
  - Added motor I2t low-speed de-rating when the motor's electrical frequency <= 5Hz
  - The I2t model de-rates the rated torque starting at 0rpm with Io/SQRT(2), using an exponential model up to 5Hz
  - The inhomogeneous heat dissipation region, is defined from 0rpm up to [nh] where [nh] is calculated using 5Hz and the motor number of pole pairs
  - The same approach is used for Linear Motors except using the pole width [m]
- PMSM
  - Improved support for IPMSM with Ld<>0, which now includes Reluctance Torque
  - This part of the motor model is still noted as 'beta' as still working with vendors to further refine the model
Motor Database Selection form
- Added "I2t" filter
Gearbox Torque Based Efficiency using Efficiency Formula
- When the Formula [Eff_Frml] checkbox is enabled, the Gearbox efficiency allows for a formula that can be a function of Input Speed [n] and Output Torque [T], allowing for more accurate efficiency modelling under different torque loads.
- The standard Efficiency vs Speed curve remains for backwards compatibility and when Formula [Eff_Frml] is not used.
Energy Storage Modules: Added 'Droop Curve' Control Mode
- Added 'Droop Curve' in addition to the existing 'Voltage Threshold' control.
- The Droop Curve configurable parameters appear in a drop-down added at the top of the Power vs Time form.
- The Droop Curve defines the control characteristics for the ESM defining the relationship between the DC Bus Voltage [Vz] and Current [Iz].
- Worth noting in the database
  - Changed Capacitance field name from [C] to [Cc] to clarify capacitance on the ESM capacitor side
  - Added a new field [Cz], for capacitance on the DC Bus, allowing for ESMs that have capacitance on the DC Bus side
Enhanced DC Bus Modelling where [Vz] Dips in Normal Mode
- In Normal mode, when Supply Peak Power Optimization (Pro version) is enabled, the DC Bus Voltage [Vz] is allowed to drop below the Nominal Bus Voltage [Vz0].
- Applies in all cases, with or without an ESM and/or KB on the DC Bus.
- But why is [Vz] allowed to drop only when Supply Peak Power Optimization is enabled?
  - Because something must "give".
  - When Supply Peak Power Optimization is enabled, the peak power limit of each Infeed Module "holds", and any additional power comes from the DC Bus, and then [Vz] decreases.
  - When Supply Peak Power is disabled, then [Vz] "holds" at [Vz0] and then any additional power comes from Infeed Module.
Enhanced DC Bus Modelling where [Vz] Dips in Backup Power Mode
- In Backup Power mode, the DC Bus voltage [Vz] is allowed to drop after the ESM and/or KB run out of energy.
- Previously in v4.5 and ealier, once the ESM and/or KB ran out of energy, Backup Power mode stopped and did not continue to run down the DC Bus.
- Now with the added capability, there are 3 tiers of backup power - ESM, KB and then the DC Bus CM bank.
- Note this applies if Supply Peak Power Optimization is enabled or disabled since the Mains Supply is gone in Backup Power mode.
Optimizer: Suggested Paramaters & Other Enhancements
- Now list suggested parameters before applying them, allowing the user to see the parameters clearly before all the fields are populated
- Added "Supply Peak Power" & "Supply Cont Power" optimization targets for Single Axis Optimization

- Max allowed DC Bus Capacitance formula (guard against high inrush current)
Inverter Ixt Thermal Overload Model
- Added Ixt_kFrml for each Ixt0, 1 & 2 in each Inverter PWM Frequency, fs0, 1, 2 & 3
- Ixt_kFrml is applied to the Ixt Fast Slow model, using the Inverter Output Frequency [fHz] and DC Bus Voltage De-rating [Vzdr] variables
- Ixt_kFrml formula can be used at any frequency range
System Check
- Added new Warning message when Vz < Vz0
  - "Bus voltage [Vz] < Nominal bus voltage [Vz0]. Contact vendor for approval"
- Conveyor
  - Added message if Max Load is exceeded
  - Added message if Moment Load Max is exceeded

    - www.companyname.com/en/drives/ProductABC.pdf
    - www.companyname.com/de/antrieben/ProductABC.pdf
  - www.companyname.com/it/azionamenti/ProductABC.pdf
  - This is accomplished by defining Language Variables in the Vendors database table under a new column named [DocPathLangVars].

Rotary & Linear Motors:
- Added [VbusMax] field, which is the "Max allowed DC bus threshold voltage"
- System Check uses VbusMax to ensure the motor is not connect to a bus voltage above what is allowed. Specifically, the check is if the DC bus Threshold Voltage > VbusMax, then a System Check alarm occurs.
- [VbusMax] can also be used in database selection to filter motors below, above a max voltage limit.
Combined Products Database form:
- Added 'Check Combinations' report for "sub-Models" in the Combined Products table. After the report runs, two new columns are added, identifiying any "sub-models" that do not exist in the main tables, along with the specific details of the missing data. For example, for a Gear Motor, perhaps the motor model does not exist in the Motors table. This report was created to address this issue. Works for all combinations including Drive Motors, Motor Linear Actuators, Motor Coupling Pumps, Gearbox Pinions, etc. A similar report was also added to the Database Utility. This goes a long way in helping vendors manage their product data in the SERVOsoft database.
