Opt. # Default Range Description
VSD Channel 6 Feedback Fault Tolerance
This is used to check that the feedback varies while modulating. For
example, if this option is set to 4%, the tolerance that is allowed while
firing is ±4% of the whole VSD range. For commissioning, the difference
between the point with the lowest feedback and the point with the highest
feedback must be bigger than twice the tolerance, so for the default of 4%
tolerance, the difference between the point with the lowest feedback and
the point with the highest feedback has to be greater than 8% of the whole
For safety reasons, options 110 – 160 must also be entered in as Parameters.
It is the responsibility of the commissioning engineer to ensure that all settings are set in accordance with the
appropriate standards, local codes and practices. If options 110 – 160 are not identical with parameters 110
– 160, then the MM will go straight to Commissioning Mode and an option/ parameter conflict message will
appear.
