xx /axis no. S The rotor position synchroniza-
tion is faulty. The difference
between the first part of rotor
position synchronization
(coarse synchronization) and
the second part (fine synchro-
nization to the active encoder
zero mark) exceeds45_electri-
cal. A too large difference may
be caused by the following:
incorrect encoder adjustment
EMC problem on zero mark
signal
too high voltage level of CD
track
S Check encoder adjustment and
EMC measures
new sequence
check mode

F045 Error code / Axis
No.
Either an encoder with distance-co-
ded reference marks has been ent-
ered by the NC or a BERO switch in
the register $1D of the motor mea-
suring system of the PCU ASIC.
This is not allowed during fine syn-
chronization which is activated by
powering up, by zero monitoring er-
ror or by deselecting the parking
axis.
After powering up, in the event of
zero monitoring errors or after dese-
lection of the parking axis, the NC/
PLC must not enter encoders with
distance-coded reference marks or
a BERO switch into the register $1D
of the motor measuring system of
the PCU ASIC.
FDD / MSD
F046 xx / xx As from drive software SW 4.02,
startup of the drive is only possible
with the drive software loaded
Re-load drive software FDD/MSD
Applies as from SW 3
300501 Current monitoring POWER ON
Cyclically after the control is switched on
Pulse reset, motor coasts down
SIMODRIVE READY and DRIVE_READY are reset.
Power On error.
1. The smoothed current amount (smoothing time: MD 1254) is greater than or equal to a current threshold.
A serious error has occurred in the current actual value acquisition.
2. With active rotor position identification (FDD only), the permissible current threshold has been exceeded.
S Up to SW 2.6 (611–D): only MSD; additionally to alarms 300502 / 300503
Current threshold = 1,2 * max. permissible power section current (MD1107)
S With SW 2.6 and higher: FDD and MSD; replacing alarms 300502 / 300503
Current threshold = 1,2 * 1,05 * max. permissible power section current (MD1107)
Check maximum power section current MD1107; replace 611D hardware if necessary
Applies with SW 3 and higher
300502 Meas. circuit error phase current R POWER ON
Cyclic after control power up
S Pulse suppression, motor runs down
S SIMODRIVE_READY and DRIVE_READY are cancelled.
S Power On error
Phase current R is greater than or equal to 1.05 times the value of the maximum permissible power section current
MD 1107. Serious error has occurred in the actual current value circuit.
S Check maximum power section current MD1107
S Defective actual current value circuit
Check maximum power section current MD1107; replace 611D hardware if necessary
Applies up to SW 4 (611–D: up to SW 2.6)
