Encoder EEPROM Enable
Encoders with a Hiperface or EnDat digital interface provide onboard EEPROM for parameter storage. This can
be used by the DS2110 to store motor related parameters so that a drive can be replaced while retaining the
motor setup. The EEPROM parameter storage is enabled by setting the parameter
encoder_eeprom_enable
to 1.
This parameter is set to 0 by default.
The parameters stored in the encoder EEPROM are:
encoder supply
encoder offset
commutation feedback source
commutation offset
motor number of poles
motor Rtt
motor Lq
motor Ld
motor Ke
motor maximum current
motor maximum velocity
motor velocity limit
current limit mask
bus over-voltage limit
