This page lists the official firmware releases of the IONI Servo Drive and the change log.

Upgrading firmware

Read instructions from Granity user guide/Uploading a firmware.

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. Very high
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
Medium
1.1.0 download 15.4.2015 1060
  • Fixes
    • Fix incorrect (too high) current scale for Brush DC motors
  • New features
  • Improvements
    • Extend the maximum range of resistance and inductance parameters from 32 ohm & mH to above 100 ohm & mH
 The new feature requires Granity V 1.6.0 Medium (High for DC motor users)
1.2.0 download 4.5.2015 1062
  • Fixes
    • Address an issue where overspeed fault (parameter FEV) has no effect and not causing fault
  • New features
  • Improvements
    • Increase feed-forward gain sensitivities: velocity FF VFF sensitivity is 30 times higher, and acceleration FF AFF is 300 times higher than before
    • Increased Phasing a.k.a. phase search algorithm motor swing to allow successful phasing in the case where motor motion is blocked in one direction
    • Motor inductance & resistance measurement function (introduced V1.1.0) adjusted to be less sensitive to motor motion during the test
 The SinCos support requires Granity V 1.7.0

Note: if acceleration or velocity feed-forward gain parameters are non-zero, re-tune the AFF and VFF gains after upgrade!

Known bugs & limitations

Bugs that are known in the latest FW revision:

  • Setpoint smoothing does not have effect in velocity or torque modes (only position mode)
