Version 1.4g
Fri, 17 Jul 2026
A913, Issuing II0 within #ININT can prevent it from being re-enabled
A914, BISS/SSI initialization in continuous mode can result in an incorrect large positive position
A936, RP incorrectly clears when using DP0 with BISS encoders, TP and RP should not change
A937, BISS _SS does not correctly report configuration
A938, SSI _SI does not correctly report configuration
A941, BI/BC initialization can fail in some cases when the axis is configured with MT-1
A943, BISS SS command does not report error when initializing with no encoder attached
A944, Commanded torque can jump to maximum value with large position error
A977, LS can cause controller to lose Ethernet connection for large programs
A989, Modbus commands that result in a modbus error can result in corrupted target array data
BISS SS command enhanced for continuous mode initialization with CDS bit
Fixed issue where BISS initialization occasionally fails with slow clock and high bit count
