88C0 Max.
nominal motor
speed %s
exceeded
 Axis: Maximum feed rate is greater than the
maximum motor speed (N-MAX) multiplied by
MP1054.
 Spindle: Maximum spindle speed is greater
than the maximum motor speed (N-MAX)
multiplied by the gear transmission ratio.
 The relationship between the line count of the
position encoder and that of the motor encoder
is faulty.
 The N-MAX entry in the motor table is faulty.
 Incorrect entry in MP2200
 EcoDyn: The selected feed rate exceeds the
max. permissible voltage.
 Check the N-MAX entry in the motor table.
 Check MP1010 and MP1054.
 Check the machine parameters for spindle
speed.
 Check the STR column in the motor table and
MP3142.
 Check MP2200.x.
8A00 No inverter
enabling %.2s
 Power-on of the drive not possible due to
missing enabling of the inverter via –SH1.
 Check the wiring.
 See ”Readiness of the inverter system” on
page 17 – 233.
 See Service Manual Inverter Systems and
Motors.
8A10 AC fail %.2s  Power-on of the drive not possible, because an
AC-fail signal (power supply) is active.
 Test the power supply.
 Check the wiring of the power supply.
 See Service Manual Inverter Systems and
Motors.
8A20 Powerfail
%.2s
 Power-on of the drive not possible, because a
powerfail signal (power supply) is active.
 Test the power supply.
 Check the wiring of the power supply.
 See Service Manual Inverter Systems and
Motors.
8A40 Enabling of
axis group %.2s
 Power-on of the drive not possible due to
missing drive enabling for axis groups (X150/
X151).
 Check the connector on X150/X151 for correct
fit.
 Check the wiring of X150/X151.
 Check MP2040.x.
 See ”Axis-specific drive enable via axis groups”
on page 17 – 232.
8A50 Inverter not
ready %.2s
 Po
wer-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 ”Readiness of the inverter system” on
page 17 – 233.
