[Encoder Config]
Configures the encoder moving average filter.
• Bits 0 “Move Avg b0”, 1 “Move Avg b1”, and 2 “Move Avg b2” - Select the moving average speed filter period (see Table 170A: Moving Average below).
Note: This parameter was added for firmware version 6.001.

[Fdbk Device Type]
The source of speed feedback. It is strongly recommended that a feedback
device be used when running a permanent magnet motor.
• 1 “Encoder” = Digital encoder (jumpers S20, S21, see page
• 2 “DC Tach” = DC analog tachometer (jumper S4, see page
• 3 “Armature” = Internal measurement of the armature voltage
• 4 “Resolver” = The resolver feedback module must be installed and
configured
Note: Option 4 “Resolver” was added for firmware version 5.002.

[Fdbk Option ID]
Displays information about the resolver feedback option module (if
installed).
Module ID (bits 15…11), Version (bits 10…6), Revision High
(bits 5…3), Revision Low (bits 2…0) (For example, a value of 6217
indicates Module ID 3, Version 1, Revision 1.1). If no resolver module is
detected this value will be set to 0.
