p1745[0...n]

Motor model error threshold stall detection / MotMod ThreshStall

VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: -
Min
0.0 [%]
Description: Sets the fault threshold in order to detect a motor that has stalled.
If the error signal (r1746) exceeds the parameterized error threshold, then status signal r1408.12 is set to 1.
Dependency: If a stalled drive is detected (r1408.12 = 1), fault F07902 is output after the delay time set in p2178.
Refer to: p2178
Note: Monitoring is only effective in the low-speed range (below p1755 * (100% - p1756)).
r1746

Motor model error signal stall detection / MotMod sig stall

VECTOR_G (n/M) Can be changed: -
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: REL
Min
- [%]
Description: Signal to initiate stall detection
Note: The signal is not calculated while magnetizing and only in the low speed range (below p1755 * (100 % - p1756)).
p1748[0...n] Motor model lower changeover speed n_set -> n_act / MotMod low n_chng
VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: ASM, PEM, REL
Min
0.0 [%]
Description: Sets the lower speed for the transition "n_set -> n_act" in encoderless operation.
This value is entered as a percentage referred to p1749.
Dependency: Refer to: p1749, p1752
p1749[0...n]

Motor model upper changeover speed / increase changeover speed /

Up/incr n_chngov
VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: PEM, REL
Min
0.0 [%]
Description: Separately-excited synchronous motor:
Sets the upper speed for the transition "n_set -> n_act" in sensorless operation.
This value is entered as a percentage of p1755.
Induction motor without speed encoder:
Depending on the machine data, the drive has calculated a minimum value of the operating frequency for rugged
operation.
If the minimum value is greater than the lower changeover limit parameterized with p1755 * (1 - 2 * p1756), then the
difference is displayed using p1749 * p1755. The parameter value cannot be changed.
Dependency: Refer to: p1748, p1752, p1755, p1756
