p2177[0...n]
Motor locked delay time / Mot lock t_del
Access level: 3
Can be changed: U, T
Units group: -
Min
0.000 [s]
Description:
Sets the delay time for the message "Motor locked" (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 before time p2177 has elapsed in order to detect
the locked state reliably.
p2178[0...n]
Motor stalled delay time / Mot stall t_del
Access level: 3
Can be changed: U, T
Units group: -
Min
0.000 [s]
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.
p2179[0...n]
Output load identification current limit / Outp_ld iden I_lim
Access level: 3
Can be changed: U, T
Units group: 6_2
Min
0.00 [Arms]
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.
p2180[0...n]
Missing output load delay time / No load t_delay
Access level: 3
Can be changed: U, T
Units group: -
Min
0 [ms]
Description:
Sets the delay time to detect a missing output load.
Dependency:
Refer to: p2179
