Description: Sets the DC link voltage threshold value for the following messages:
"Vdc_act <= Vdc_threshold p2172" (BO: r2197.9)
"Vdc_act > Vdc_threshold p2172" (BO: r2197.10)
Dependency: Refer to: p2173
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 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
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 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 p1750.6 is set to 1.
