Diagnostics and troubleshooting
− 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
− 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
− 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
− 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
Check position and strength of the belt
− 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)
