EMB(0) and EMB1
The electromechanical bypass is available in two
additional types, the EMB(0) and EMB1. Each has
reduced functionality from the EMB2. The figures
and tables below list for features and functions
available in either type. Table 5-6 lists EMB1 default
parameter settings for bypass operation. If the drive
is reinitialized, be sure that these settings are
maintained or reset for proper bypass operation.
See the mechanical layout diagram inside the cover
of the unit for connector locations within the unit.
