Table 5-2 Technical data of EB1
If the inverters/converters are ordered with optional functions, the
optional boards are already installed in the units when they are
delivered.
It is possible to retrofit optional boards and this can be carried out by
the user.
For this purpose, there are either two or up to six slots on the basic unit
depending on the type of construction for mounting the optional boards.
An exact description of installation is included with the relevant basic
unit. As the unit has to be removed and opened in order to install
optional boards, attention must be paid to the ESD measures. Please
refer to the operating instructions of the basic unit in this regard.
Generally, you can install the EB1 optional board in every slot.
However, please observe that an encoder board for MASTERDRIVES
Motion Control always requires slot C.
A maximum of two EB1s can be installed per unit.
