Modifications and Improvements, October 2012
The following modifications are included in Geo Brick Drive units shipped in
October 2012 and later.
These units can be recognized by the new 24V logic connector which includes the
Safe Torque Off (STO) pins.
Control board
 New board layout
 Revision upgrade from 603793-10x to 603793-10B
 Better memory lines routing
 Improves and allows operation at full 240 MHz CPU capability (previously
recommended running at 230 MHz)
 Resolves intermittent SAVE time-out and loss of configuration with 240MHz CPUs
 Resolves operation of 80 MHz CPUs with large memory
 Better power distribution
 Minimizes noise disturbance
 Resolves intermittent MACRO data blips (e.g. motor position spikes)
 More robust digital outputs protection
 Self-protected MOSFETS: over voltage, over current, I2T, short circuit
Power board(s)
 New board layout
 4- and 8- axis upgrade from 603800 to 603967
 6-axis upgrade from 603803 to 603968
 Added Safe Torque Off (STO) feature
 Added internal shunt resistor
 Updated amplifier firmware
 More robust fault triggering and trapping
 Added AF2 fault code for STO support
 Added “instantaneous” capacitors discharge upon disconnecting bus power
 Improved on DC-DC power supply design
 Increased capacity from ~5A to ~8A at 24VDC
 Faster rise time, and settling time
 More stable (less ripple) +5V which supplies the controller, encoders, and add-in board
 Improved on AC power lines distribution
 Minimizes noise disturbances
 Improved grounding scheme
