Input of maximum thermally permissible current of power section. The input is an RMS value.
This machine data is automatically parameterized for Siemens power sections by the machine
data "Power section code number" (MD 1106). The value entered must correspond to the limit
value specified on the power section rating plate.
Caution:
This data acts as the upper thermal loading limit and must not be changed by the user after
automatic presetting of its values.
1109
This machine data is used to enter the maximum permissible current of the power section
referred to the S6 duty cycle (intermittent operation). The input is an RMS value. This machine
data is automatically parameterized for Siemens power sections by machine data "Power
section code number" (MD 1106). The value entered must correspond to the S6 current
specified on the rating plate of the appropriate MSD power section.
Caution:
This data must not be changed by the user after automatic presetting of its values.
Note:
This data is relevant only for MSD drives.
1111
The maximum permissible power section continuous current is entered in this machine data.
The input is an RMS value. This machine data is automatically parameterized for Siemens
power sections by machine data "Power section code number" (MD 1106). The value entered
must correspond to the rated current specified on the rating plate of the appropriate power
section.
Caution:
This data must not be changed by the user after automatic presetting of its values.
