5.1.1 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 5.7
,
Table 5.8
and
Table 5.9
list terminal functions for EMB(0) and EMB1, respectively, and 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.
