8A40 Enabling of
axis group %.2s
 Because of missing drive enabling for axis
groups (X150/X151), the drive cannot be
switched on.
 Check the connector on X150/X151 for
correct fit.
 Check the wiring of X150/X151.
 Check MP2040.x.
 See “Checking the drive enabling for the
axis groups via connector X150 and X151 (if
wired)” on page 16 – 242.
8A50 Inverter not
ready %.2s
 Power-on of the drive not possible, because
an inverter is not ready (RDY signal).
 Check the Ready LED of the inverter.
 Check the wiring of the inverter.
 On interface PCBs for Siemens inverters,
the second axis is not enabled.
 See “Checking the readiness of the inverter
system” on page 16 – 243.
