p2174[0...n] Torque threshold value 1 / M_thresh val 1
Access level: 3
Can be changed: U, T
Unit group: 7_1
Min
0.00 [Nm]
Description: Sets the torque threshold value for the messages:
"Torque setpoint < torque threshold value 1 and n_set reached" (BO: r2198.9)
"Torque setpoint < torque threshold value 1" (BO: r2198.10)
"Torque setpoint > torque threshold value 1" (BO: r2198.13)
Dependency: Refer to: p2195, r2198
p2175[0...n] Motor blocked speed threshold / Mot lock n_thresh
Access level: 3
Can be changed: U, T
Unit group: 3_1
Min
0.00 [rpm]
Description: Sets the speed threshold for the message "Motor blocked" (BO: r2198.6).
Dependency: Refer to: p0500, p2177, r2198
Refer to: F07900
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.
The following applies for sensorless 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 p1750.6 is set to 1.
p2176[0...n] Torque threshold value comparison delay time / M_thrsh comp T_del
CU250S_V (Ext msg) Access level: 3
CU250S_V_CAN (Ext
Can be changed: U, T
msg)
Unit group: -
CU250S_V_DP (Ext
Min
msg)
0 [ms]
CU250S_V_PN (Ext
msg)
Description: Sets the delay time for the comparison of the torque actual value (r0080) with torque threshold value 1 (p2174).
Dependency: Refer to: p2174
p2177[0...n] Motor blocked delay time / Mot lock t_del
Access level: 3
Can be changed: U, T
Unit group: -
Min
0.000 [s]
Description: Sets the delay time for the message "Motor blocked" (BO: r2198.6).
Dependency: Refer to: p0500, p2175, r2198
Refer to: 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).
