Cause
Drive hardware setup is
initializing.
1 - Initializing HW settings for
the first time.
Safe torque off function is
active, ie safety circuit signal(s)
connected to connector STO is
lost.
Problem with internal
temperature measurement of
the drive.
Power unit power supply
failure.
Measurement circuit fault.
Measurement circuit fault.
State feedback from output
phases does not match control
signals.
Charging feedback signal
missing.
Duplicated measurements are
beyond limits.
Excessive hardware
temperature.
The flash memory (in the
memory unit) has been erased
too frequently, compromising
the lifetime of the memory.
The motor parameters are set
incorrectly.
The drive is not dimensioned
correctly.

What to do
See auxiliary code.
Check safety circuit connections. For
more information, chapter The Safe
torque off function in the Hardware
manual of the drive and description of
parameter 31.22 STO indication run/stop
(page 109).
Check the value of parameter
Control board supply.

Avoid forcing unnecessary parameter
saves by parameter 96.07 Parameter
save manually or cyclic parameter writes
(such as user logger
triggering through parameters).
Check the auxiliary code (format XYYY
YZZZ). "X" specifies the source of
warning (1: generic flash erase
supervision). "ZZZ" specifies the flash
subsector number that generated the
warning.
Check the auxiliary code. See actions for
each code below.
