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 controller, the setting of the limit value I

ULT

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.
