Belt Failure
Detected
 Load conditions on motor indicate belt
failure or mechanical fault.
Check the following:
1. No breakage, seizure or obstruction of drive train.
2. Proper operation of external speed sensor, if in
use.
3. P0402 (pulse per min at rated speed), P2164
(Hysteresis freq. deviation) and P2165 (delay
time for permitted deviation) must have correct
values.
4. P2155 (threshold frequency f1), P2157 (threshold
frequency f2)P2159 (threshold frequency
f3)P2174 (upper torque threshold 1)P2175 (lower
torque threshold 1)P2176 (delay T_Torque)P2182
(upper torque threshold 2)P2183 (lower torque
threshold 2)P2184 (upper torque threshold 3) and
P2185 (lower torque threshold 3) must have
