170 [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.
414 [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 76
)
• 2 “DC Tach” = DC analog tachometer (jumper S4, see page 76)
• 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.

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.
