- Added possibility to disable hard stop detection in homing (set zero to Hard stop detection thresholdHMH)

| 1.4.0 download |
31.12.2015 |
1084 |
- Improvements
- IONI Pro HC model maximum output current in AC/BLDC/Stepper modes increased to 25A (was 23A)
- Re-implemented torque controller using 32 bit floating point arithmetics instead of integer arithmetics (at least theoretical precision improvement)
- DC motor mode no longer requires parallel connection of drive output phases if current is at most 50% of drive's maximum output current capability (sensitivity of overcurrent fault with Fault ID 440219 is greatly reduced).
- Fixes
- Changed limit switch polarity: earlier limit switches needed to be normally open (NO), while drive specifications say that they are normally closed type (NC). Now limit switchers are NC (switch conducting -> motion allowed, switch open -> motion stops).
- Fix an issue where AC/BLDC motor initialization could become incorrectly phased when Hall sensors are enabled
- Address an issue where torque was 5% lower than setpoint with TBW parameter value of 4700 Hz
|
- Test the upgrade with caution due to significant internal changes

- Power consumption limit parameter added (allow setting maximum power driven to motor)
- SimuCUBE support added in Electrical interfaceCEI. In SimuCUBE mode:
- STO input acts also as Enable and Clearfaults input
- Regenerative resistor drive algorithm is tuned for SimuCUBE (tip: use 48 VDC PSU and set Over voltage fault thresholdFOV to 49-50V)
- Power consumption limit is smoother in SimuCUBE mode than in other modes
- New features (all models):
- Support for fast setpoint command added in SimpleMotion V2 protocol
- In torque mode the Tracking error capture channel now displays the difference between raw unfiltered setpoint and realized actual torque in milliamperes
- Improvements
- Smoother multi-axis operation in buffered motion stream mode (SimpleMotion V2)
- Drive now performs a self-test of the internal RAM of controller at every power-on

6.6.2016 |
1094 |
- Improvements
- Operation of regenerative resistor drive enhanced in SimuCUBE Electrical interfaceCEI mode

Medium
|
| 1.5.2 |
4.8.2016 |
1096 |
- New features
- It is now possible to use torque cogging & ripple compensation parameters for open loop stepping motors to reduce stepper noise and vibration
- New safety feature: monitoring of actual torque vs target torque. If torque is significantly above torque setpoint (i.e. loss of torque controller stability occurred), then drive will stop in over current fault with Fault location 442001
- Improvements
- Eliminated motion glitch during motor initialization
- Enhanced open loop stepper signal processing: motor will stay quiet at stand still at any angle (note: KVI and KVP values need to changed, see Using stepping motor with IONI for details.
- Fixes
- Fixed buffered motion stream glitch that could sometimes cause corruption of instant SimpleMotion command return values while buffered motion is running. Typical symptoms of this glitch are Fault location 480501 and skipping of motion samples.
- Addressed instability of torque controller with high coil resistance motors
|
In open loop stepper mode, update KVI and KPP parameters according to page Using stepping motor with IONI

| 1.5.4 download |
8.9.2016 |
1100 |
- Improvements
- General purpose inputs (GPI-pins) of drive are now noise/glitch/debounce filtered. Now digital input state change requires that signals stays stable for 10 milliseconds before it is interpreted as state change.
- Prevent overloading of regenerative resistor by the means of:
- Drive will not enable regenerative resistor until HV DC bus voltage has been within valid voltage range with 2% safety margins from Under voltage fault thresholdFUV and Over voltage fault thresholdFOV at least once
- Pulsing frequency of regenerative resistor has been increased
- Maximum heat load of regenerative resistor in SimuCUBE mode has been reduced
- Fixes
- I²t protection time scale is corrected (earlier versions had wrong scale in Thermal time constantMTC meaning that the protection was bit too conservative, by about 20% difference)
|
It may be necessary to decrease FUV and/or increase FOV parameter values to make drive initialize as the new changes requires 2% safety headroom for these values versus actual supply voltage.
I.e. for 48.0V supply voltage, the FUV value should be less than 48*0.98=47V and FOV should be greater than 48/0.98=49V.
In practice, make allowed voltage range at least 0.5V wider to allow supply voltage variation, like FUV=46.5V and FOV=49.5V or greater.
For more information, see Configuring drive voltage limits FUV and FOV

19.12.2016 |
1102 |
- Improvements
- Support changing limit switch polarity (requires Granity 1.10.2)
- Limit switch polarity default setting changed. Now default setting assumes normally closed switches, instead of normally open type.
- Added soft current ramp-up for open loop stepping motors
- Tracking error warning flag is now controlled also in torque mode (of torque error is greater than 25% of peak current parameter MMC, the tracking error warning flag goes logic true)
- SimpleMotion bus baud rate now resets to the default if connection watchdog timeout occurs
- Fixes
- Address an issue where I²t protection did not react (in some cases allow motor overheating)

16.1.2017 |
1104 |
- Improvements
- Overcurrent fault with Fault location 402001 can not occur any more if Over current toleranceFOC is set to Maximum
- Increased error tolerance for Fault location ID 250101
- Fixes

14.2.2017 |
1108 |
- Improvements
- Support for new production run IONI drives (a requirement for drives manufactured after 1.2017)
- Support for custom 7 axis motherboard added (similar to IONICUBE but customer design)
|
This, or later version is required for drives manufactured after 1.2017 due to minor hardware change. Installing older FW version on such device will cause update error and requires re-update.
