Motor Model Status / Motmod Status - Siemens SINAMICS G150 Manual

2 Parameters
2.2 List of parameters
As an alternative to a warm restart: save the parameters and carry out a POWER ON (switch-off/switch-on).
When the function "safety without encoder" (p9306/p9506) is activated, this setting is not permissible and results in
monitoring errors.
Re bit 6 = 1:
The following applies for encoderless vector control of induction motors:
For a blocked motor (see p2175, p2177) the time condition in p1758 is bypassed and a change is not made into
open-loop controlled operation.
The following applies for encoderless vector control of synchronous motors:
For a blocked motor (see p2175, p2177), the speed ramp-function generator is held in open-loop speed controlled
operation, and a change is not made into closed-loop controlled operation.
Re bit 7 = 1:
The following applies for encoderless vector control of induction motors:
If the changeover limits are parameterized too low (p1755, p1756), then they are automatically increased to rugged
values by the absolute amount p1749 * p1755.
The effective time condition for changing over into open-controlled operation is obtained from the minimum of p1758
and 0.5 * r0384.
Activation can make sense for applications that demand a high torque at low frequencies and therefore low speed
gradients.
Adequate parameterization must be ensured (p1610, p1611).

Note: Re bit 17:
Displays the status when enabling the rugged model feedback (p1784) for operation with and without encoder.
The feedback is used to increase the parameter ruggedness of the motor model and is effective in the operating
range of the two-component closed loop current control.
