Please note: The following parameters are optional and it is not recommended to mod-
ify them since they are optimized from factory.
The following 2 registers are relevant for the closed loop operation
Motor commutation and encoder setup:
1. KPHASE - register that offsets the magnetic field as function of the velocity
See also: Internal_Encoder_Setup, page 225
2. Internal_Encoder_Setup - register that define the encoder resolution and other en-
coder related parameters. See also: Internal_Encoder_Setup, page 225
Current control advanced registers:
None of the below shown registers are accessible from MacTalk but only from other
protocols such as Ethernet, Modbus, CANopen etc.
The registers shown below are all related to optimizing the current control performance.

ment rate.
