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.
The following applies for encoderless vector control for permanent magnet synchronous motors:
At low speeds in open-loop speed controlled operation (see p1755, p1756), a blocked motor can only be detected if
p2175 = p1755, and p1750 bit 6 is set to 1.
Description: Sets the delay time for the comparison of the torque actual value (r0080) with torque threshold value 1 (p2174).
Dependency: Refer to: p2174
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.
Description: Sets the current limit for output load identification.
Dependency: Refer to: p2180
Notice: For synchronous motors the output current can be almost zero under no load conditions.
Note: A missing output load condition exists if the motor is either not connected or a phase has failed.
