2. Some control board tests have failed.
4. Some functional test have failed.
8. Some I/O module tests have failed.
16. Internal RAM failed on power-up check.

F0452
Belt failure
detected
Ø
Load condition changes at the motor
indicate a belt failure or mechanical fault.
Check the following:
1. Drive belt ok. The drive is not obstructed or seized?
2. If external speed sensor is used, check proper
function. Check the following parameters:
P0409 (impulses/sec on nominal speed)
P2191 (belt failure and speed monitoring)
P2192 (delay time for P2191).
3. For belt failure detection without sensor, check the
following parameters:
P2182 (threshold frequency f1)
P2183 (threshold frequency f2)
P2184 (threshold frequency f3)
P2185 (upper torque threshold 1)
P2186 (lower torque threshold 1)
P2187 (upper torque threshold 2)
P2188 (lower torque threshold 2)
P2189 (upper torque threshold 3)
P2190 (lower torque threshold 3)
P2192 (delay for belt failure).
4. Lubricate the drive if necessary.
