*Selection of operating characteristics of thermal monitor (I2t monitoring) of

(G101)	power section (see also Section 9.16 ”Dynamic overload capability of power
	section”).
(G161)
	The ”Dynamic overload capability of the power module“ allows the
	SIMOREG DC Master to operate for short periods on armature currents that
	are higher than the converter rated DC current specified on the rating plate
	(=r072.001).
	The permissible overload period is determined solely by the power module
	and the preceding operating history.
	The "thermal power module monitoring" function does not monitor operation
	in compliance with the load class criteria set in parameter P067. If permitted
	by the power module, the unit can operate for overload periods in excess of
	those defined by the load class.

0Dynamic overload capability is not permitted

The armature current is limited to P077 * r072.001.

1Dynamic overload capability is permitted, alarm A039

The armature current is limited to P077 * 1.8 * r072.001 as long as the calculated thyristor temperature does not exceed the permitted value.

If the temperature exceeds the permitted value, the SIMOREG DC Master protects itself by reducing the current limit to P077 * r072.001. Alarm A039 is output at the same time.

The armature current setpoint limit is not increased to P077 * 1.8 * r072.001 (alarm A039 also disappears) until the calculated thyristor temperature has dropped below the limit value again and the armature current setpoint is lower than the converter rated DC current (r072.001).

2Dynamic overload capability is permitted, fault F039

The armature current is limited to P077 * 1.8 * r072.001 as long as the calculated thyristor temperature does not exceed the permitted value.

Fault message F039 is output if the permissible temperature limit is exceeded.
