F07900 Drive: Motor blocked/speed controller at its limit
Message class: Application/technological function faulted (17)
Message value: -
Component: Motor
Response: OFF2
Acknowledgment: IMMEDIATELY
Cause: The motor operates longer than 0.2 seconds at the torque limit and below the speed threshold in p2175.
This
signal can
also be initiated if the speed actual value is oscillating and the speed controller output repeatedly goes to
its limit.
See also: p2175, p2177
Remedy: - Check that the motor can freely move.
- Check the e󹪜ectiv
e torque limit (r1538, r1539).
- Check the parameter of the "Motor blocked" signal and possibly correct (p2175).
F07901 Drive: Motor overspeed
Message class: Application/technological function faulted (17)
Message value: -
Component: Motor
Response: OFF2
Acknowledgment: IMMEDIATELY
Cause: The maximum permissible speed was either positively or negatively exceeded (p1082).
Remedy: - Check the speed controller (p1460, p1462).
- Chec
k the moment of iner
tia (p1498).
- Check the maximum speed (p1082).
A07920 Drive: Torque/speed too low
Message class: Application/technological function faulted (17)
Message value: -
Component: Motor
Response: NONE
Acknowledgment: NONE
Cause: The torque deviates from the torque/speed envelope characteristic (too low).
Remedy: - Check the connection between the motor and load.
- A
