Description: Sets the delay time for the comparison of the DC link voltage r0070 with the threshold value p2172.
Dependency: Refer to: p2172
Description: Sets the speed threshold for the message "Motor blocked" (BO: r2198.6).
Dependency: Refer to: p0500, p2177, r2198
Note: The following applies for encoderless vector control for induction motors:
At low speeds in open-loop speed controlled operation (see p1755, p1756), a blocked motor cannot be detected.
Description: Sets the delay time for the message "Motor blocked" (BO: r2198.6).
Dependency: Refer to: p0500, p2175, r2198
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).
Description: Sets the delay time for the message "Motor stalled" (BO: r2198.7).
Dependency: Refer to: 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.
