ver 2.25.05 16 May 2022 All motors: Prevent outside sources from setting active mode until STO is completely cleared Fixed High resolution position mode MAC1500 and MAC3000G: Efficiency of internal power dump improved (only for 1ms sample time) MAC3000G: Powerdump threshold voltage reduced. MAC400: Optimized I2T. ---------------------------------------------- ver 2.25.2 4 Feb 2022 Fixed EtherCat issue for all MAC motors ---------------------------------------------- ver 2.25.0 11 Jan 2022 MAC140F: - Initial release MAC400 / MAC400G / MAC402 / MAC1500 / MAC3000 / MAC3000G / MAC4500 : - Fixed problem with encoder direction when using gear out on absolute encoder motors ---------------------------------------------- ver 2.24 04 June 2021 Fixes : - I2T scaling updated to prevent overflow (MAC402) - Fixed issues with analogue torque mode ---------------------------------------------- ver 2.23 14 Jan 2021 AD Improvements: - Added commands 100 and 101 for factory testing. - Handling of CRC-errors from Absolute encoders improved. - Support for brake burn-in activation via command. Fixes: - Startup issue with abs.enoder flash backup fixed. V2.23 is more robust against electrical noise, so if you experience false overspeed errors, we recommend that you update from v2.22 to v.2.23. ---------------------------------------------- ver 2.22 24 Mar 2020 AD New features: - Support for MAC3000-Gx motor series. - Support for reading the full product key as a string, like MAC3000-G2-FAAL-A025. - Support for 64 times higher resolution of velocity and acceleration setpoints. Results in better than 0.01 RPM. NOTE: This also allows a larger working range in Position mode. Please ask JVL for full documentation. (HiRes Vel/Acc will not work in Gear mode or dispenser mode) - New system to dynamically adjust the Load Factor depending on actual velocity to avoid oscillations with mainly belt drives. - Added option of 10 and 20 kHz PWM switching to motors with default 5 kHz switching frequency, to reduce audible noise. Note motors will be much warmer, and CANNOT deliver rated power without overheating when this feature is enabled. - Added option for Silent Mode, that softens the current regulation at the cost of (potentially much) lower dynamic response and efficiency. For use in sensitive audio environments. Not supported on MAC800 and standard MAC400. Improvements: - Support MAC4500-Gx motors. - Better handling of return energy for the MAC402 motor. - Shows Build number and FPGA version in Reg253, 254. - Re-introduced time to re-calibrate current measurements offsets when switching from passive mode to active modes. - Supports two differnet sample points for Ethernet SYNC operation to support more types of PLC Ethernet masters. - Increased the amount of energy the internal brake resistor can receive (MAC1500, MAC3000, MAC3000G, MAC4500 only). - Improved handling of sporadic encoder noise in velocity measurement. Fixes: - Using heavy communications, mainly over Ethernet, with Scope data no longer causes jumps in motor movements. - MacTalk,Modbus RS485 communications on MAC00-B42 modules fixed. - Supports faster read/write of on-the-fly scaling parameters. - Better timeout monitoring of ePLC serial communications. - The system can now start up after reset with an Ethernet module also when on-the-fly scaling for Modbus is enabled. - Now supports all baud rates 9600 through 1.000.000 using RS485 on MAC00-B41/B42 also with MAC800/MAC1000/MAC1200. - Fixed an extra turn when using Rotary Table mode. - Fixed a rare problem (seen in-house only) with startup of the ePLC program. - Edge detection on digital inputs in the ePLC program now optimized to work with latest hardware. ver 2.20 and ver 2.19 3 Jan 2020 and 14 Dec 2019 AD These releases were recallled due to long startup time and false UIT errors. ---------------------------------------------- NOTE: Beginning from release v2.19, these releasenotes will have the same text for all motor types. Previously each motor type described changes only relevant for its model. ----------------------------------------------
