Hardware

 

IUnom.: unit nominal current IUP: unit peak current IMnom.: motor nominal current

Dynamic monitoring:

In COMPAX, the nominal current value is limited to the smallest value of the following 3 quantities.

IUP: unit peak current

P105 * P107: nominal motor current (P105) * maximum pulse current permitted for the motor (P107)

P105 * P16: nominal motor current (P105) * maximum permitted (user-set) torque (P16)

Static monitoring

This executes triple monitoring:

 

Unit monitoring

Using the unit-specific time constant TG, a current greater than

 

IUnom. is permitted for a specific period; E53 then switches the unit

Motor monitoring

off.

Using the time constant TM, a current greater than 1.1 * IMnom. is

 

permitted for a specified period; E53 then switches the unit off.

 

TM is set so that the pulse current P107 can flow for the period set

Final stage / short circuit monitoring

in P108.

Absolute monitoring to 1.5 * IUP.
