8.8 Monitoring of the ultimate motor current
0x2D46 | 0x3546 - Monitoring: Ultimate motor current
 Stop!
The parameterisable ultimate motor current I
ULT
is a limit value the exceedance of which
causes non-reversible damages of the motor!
Examples:
• Demagnetisation of single rotor magnets when the PM servo motor is operated.
• Destruction of the stator winding.
This limit value must not be travelled cyclically in the drive process!
The maximum current (0x6073
or 0x6873 for axis B) parameterised should provide a
sufficient distance to this ultimate motor current.
 Note!
When you select a Lenze motor from the catalogue and transfer the parameters of the
motor to the servo inverter, the setting of the I
ULT
limit value is automatically adapted
to the motor selected.
In case of motors of other manufacturers, we recommend the parameterisation of the
limit value I
ULT
in 0x2D46:1 (or 0x3546:1 for axis B) to be executed as one of the first
commissioning steps.
If the instantaneous value of the motor current exceeds the limit value set, the response
set for this monitoring function is triggered in order to protect the motor.
