PID feedback
below min.
value
PID feedback below minimum value of P2268
Check settings of the VSD’s PID control loop
Change the value of P2268
A reset to the default values cancels all undesired
parameter settings and retrieves the default settings.
The VSD must be recommissioned

value
PID feedback above maximum value of P2267
Check the settings of the VSD’s PID control loop
Change the value of P2267
A reset to the default values cancels all undesired
parameter settings and retrieves the default settings.
The VSD must be recommissioned

BIST tests
failure
VSD self-test failed. Cause can be found based
on error value in parameter r0949:
r0949 = 1 Tests on power section failed
r0949 = 2 Tests on control section failed
r0949 = 4 Function tests failed
r0949 = 8 Tests on I/O module failed
r0949 = 16 Error of internal RAM test when
switching on
Switch the VSD off and on again
A reset to the default values cancels all undesired
parameter settings and retrieves the default settings.
The VSD must be recommissioned
If the fault cannot be rectified by making a reset to
the default settings, the VSD must be replaced
OFF2
Belt failure detection without sensor (refer to
section 8.1)
Check the settings of the following parameters and
compare them with the torques currently measured
via parameter r0031:
P2182 (frequency theshold f1)
P2183 (frequency theshold f2)
P2184 (frequency theshold 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 (time delay load torque supervision)
Tolerance bands of more than 50% must be set,
depending on the type of application
Belt faulty Check position and strength of the belt
F0452
Belt failure
detected
Belt failure detection with sensor (refer to
section 8.2)
Check to ensure that the sensor is correctly
connected to digital input # 5
Check settings of the following parameters:
P0400 type of sensor
P0409 (pulses / s at rated speed)
P2181 (triggering conditions)
P2191 (speed supervision tolerance)
P2192 (time delay for P2191)
