Dependency: See also: p0500, p2177, r2198

Note
The following applies for sensorless vector control for induction motors:
At low speeds in open-loop speed controlled operation (see p1755, p1756), a blocked motor cannot be detected.
p2177[0...n] Motor blocked delay time / Mot lock t_del
Access level: 3 Calculated:
CALC_MOD_LIM_REF
Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: 8012
Min:
0.000 [s] Max:
65.000 [s] Factory setting:
3.000 [s]
Description: Sets the delay time for the message "Motor blocked" (BO: r2198.6).
Dependency: See also: p0500, p2175, r2198
See also: F07900
Note
The following applies for sensorless vector control:
At low speeds a locked motor can only be detected if no change is made to open-loop speed controlled operation. If this
is the case, the value in p2177 must be reduced accordingly (p2177 < p1758) before time p2177 has elapsed in order
to detect the locked state reliably.
As countermeasure, it is generally also possible to set p1750.6. This is only not permitted if the drive is slowly reversed
by the load at the torque limit (speed below p1755 for longer than p1758).
p2178[0...n] Motor stalled delay time / Mot stall t_del
Access level: 3 Calculated: CALC_MOD_REG Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: 8012
Min:
0.000 [s] Max:
10.000 [s] Factory setting:
0.010 [s]
Description: Sets the delay time for the message "Motor stalled" (BO: r2198.7).
Dependency: See also: r2198
Note
In the open-loop speed controlled operating range (see p1755, p1756), vector control stall monitoring depends on
threshold p1745.
At higher speeds, the difference between flux setpoint r0083 and flux actual value r0084 is monitored.
p2179[0...n] Output load identification current limit / Outp_ld iden I_lim
Access level: 3 Calculated:
CALC_MOD_LIM_REF
Data type: FloatingPoint32
Can be changed: T, U Scaling: p2002 Dynamic index: DDS, p0180
Unit group: 6_2 Unit selection: p0505 Function diagram: 8022
Min:
0.00 [Arms] Max:
1000.00 [Arms] Factory setting:
0.00 [Arms]
Description: Sets the current limit for output load identification.
A missing output load is displayed using the "Output load not available" message (r2197.11 = 1).
This message is output with a delay time (p2180).
Dependency: See also: p2180
NOTICE
For synchronous motors the output current can be almost zero under no load conditions.
