Installation
PO = (Percent)(Max Rating)P(O) = % x P(MO)
PO = (0.6)(175 watts) = 105 watts
This value can be substituted in the total power loss calculation:
PT = PSB + PO + PSR
PT = 50 watts + 105 watts + 220 watts = 375 watts
Contact the EMERSON Motion Control Applications Engineering department if you have
any questions concerning power losses.
Actual shunt regulation losses will vary from the values listed above. In most applications the
actual power loss will be less than the value in Table 7, “Power Dissipation,” on page 29. The
actual shunt regulation losses is unique for every application. EMERSON Motion Control
recommends using the values in Table 7, “Power Dissipation,” on page 29 for calculating
proper enclosure size.
Mode Selection (Basic Drive Setup)
Indexing Mode
The primary operating mode of the FX drive is the Indexing mode. The Indexing mode is
available at all times and is independent of any alternate operating mode switch settings. The
table below shows two means of initiating the Indexing mode.
.
Setting Other Modes
In addition to the Indexing mode, four alternate modes are also available. These modes are
called Analog Velocity, Analog Torque, Pulse/Pulse and Pulse/Direction.
Switches 3 and 4 of the four position DIP switch configure the alternate operating modes.
