Releases

Glossary

• Firmware release version - a firmware file with .gdf name extension that contains the firmware firmware
• Version code - the version shown in Granity
• Change log - the list of changes made since the previous package version.
• Remarks - Notes

Firmware release version	Date	Version code	Change log	Remarks	Importance
1.0.0	15.3.2015	1050	Initial version
1.0.1	19.3.2015	1052	Address an issue where device may trigger watchdog reset under heavy use		Medium
1.0.2	11.4.2015	1054	Fixes Fix Phasing a.k.a. phase search current calculation when MTC is set below 400 seconds. Avoids too high current flow to motor. Fix overcurrent condition observer (OC fault was not always triggered when it should). Fix incorrect setpoint scaling when using CIS Setpoint smoothing function (before 1.0.2 CIS caused setpoint to incorrectly scale by 1:2) Fix functionality of GPI5 input (homing start) Fix override parameter function (more info: Reading and writing an arbitrary parameter with Granity) Improvements Reduce Phasing a.k.a. phase search current to avoid motor heating at initialization Improve open loop stepping motor performance GPO3 (fault output) will be push-pull instead of open drain when electrical interface is set Standard (for IONICUBE 1X compatibility) IONI Indiegogo campaign drives have 18 Amp maximum current limit instead of 15 A (serial number based)	Important upgrade due to overcurrent protection fix and phasing current calcuation fix.	Critical
1.0.3	12.4.2015	1056	Fixes Fix clear faults command by Enable signal in IONICUBE electrical interface mode Fix PWM setpoint operation after setpoint source has been changed from pulse/direction to PWM Improvements Stepping motor has automatic current reduction/boost depending on whether motor is standing still or rotating (switch between configured continuous and peak current).		Medium
1.0.4 download	13.4.2015	1058	Fixes Address an issue where Achieved torque readout & graph was showing only zero Improvements Improve Phasing a.k.a. phase search algorithm speed		Medium

Known bugs & limitations

Bugs that are known in the latest FW revision:
