7.7.8 Parameters 51-02, 52-04, and 52-49: Application Settings (0x2016)

There are several general settings regarding the behavior of the servo drive.
Sub-index 01: Observer speed enable
Enables the speed observer. The purpose of the observer is to improve the quality of the calculated speed signal from
position sensor. When enabled, the control bandwidth is higher.
Sub-index 02: Drive mirror mode
This object provides a way to set/clear the drive mirror mode. Setting mirror mode reverses the turning direction of the axis,
useful when, for example, it is used with an inverting gear box.
Sub-index 03: Save position offset
Write 1 to save the position offset to non-volatile memory. After it is saved, the servo drive writes a 0 back to the object so
that it can be rewritten with 1. If a new homing process starts, the position offset is overwritten, but not stored automat-
ically. If the servo drive is reset, the last saved position offset is reused. The Is Homed bit in the Statusword is not set during
start-up. It is only set if a new homing procedure completed successfully.
For single-turn encoders, only the fractional part is preserved.
