Shear Pin Cfg
Shear Pin Configure
RW 16-bit
Integer
Configures operation of the shear pin function.
Bit 0 “Shear1NoAcc” – 0 = Active during acceleration, 1 = Ignore during acceleration
Bit 1 “Shear2NoAcc” – 0 = Active during acceleration, 1 = Ignore during acceleration

Shear Pin 1 Actn
Shear Pin 2 Actn
Shear Pin n Action
Configures the action to take when the output current is greater than or equal to P436/
439 [Shear Pin n Level] for the amount of time set in P437/440 [Shear Pin n Time]. These
two independent shear pin functions can be set up to achieve the equivalent of external
overloads that have “stall” and “jam” indication.
“Ignore” (0) – No action is taken.
“Alarm” (1) – Type 1 alarm indicated.
“Flt Minor” (2) – Minor fault indicated. If running, drive continues to run.
Enable with P950 [Minor Flt Cfg]. If not enabled, acts like a major fault.
“FltCoastStop” (3) – Major fault indicated. Coast to Stop.
“Flt RampStop” (4) – Major fault indicated. Ramp to Stop.
“Flt CL Stop” (5) – Major fault indicated. Current Limit Stop.
Default:
Options:
0 = “Ignore”
0 = “Ignore”
1 = “Alarm”
2 = “Flt Minor”
3 = “FltCoastStop”
4 = “Flt RampStop”
5 = “Flt CL Stop”
