官方故障排除步骤
ax-grp A [Cause of error] The cutout channel test detected a fault: The CC-specific pulse deletion for the corresponding power modules of the NC axis group (A) over the A channel is defective. Switch-off signal: STO.A.MC.WD Switch-off signal: STO.A.x At least one of the acknowledgment signals for this cutout channel has the wrong condition, i.e. when - JH inverter: At least one power module reports "readiness" (RDY.x=1), although for all power modules of the axis group A of the CC, "No readiness“ (RDY.x=0) is expected. - DRIVE-CLiQ inverter: At least on of the associated diagnostic signal is "1", although "0" is expected.
