• Support for Pole position identification

( 128) in the case of torque and linear motors by means

of

• movement to a machine position in which pole position identification can be carried out in a

reproducible manner and

• setting of the pole position angle with the "PL touch probe signal"

 Stop!

At the frequency f

d

= 0 Hz, the r.m.s. value increases to 141 % of the current

parameterised in C02773/x

. As a result, the connected motor can be destroyed!

Remedy:

Activation of a derating curve in i2xt monitoring or limitation of the

parameterised current in C02773/x

to 71 % of the rated motor current. Motor
