EtherCATEtherCAT is an open, high-performance Ethernet-based fieldbus system. The development goal of EtherCAT was to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs COE and CANopen	508Fh/0	M_01-00-00-000

Description

This parameter sets whether the initial value of the feedback read from the feedback deviceA process whereby some proportion of the output signal of a system is passed (fed back) to the input. In automation, a device coupled to each motor to provide indication of the motor's shaft angle, for use in commutating the motor and controlling its speed and position will be set as a signed or as an unsigned value.

0 = Unsigned

1 = Signed

The drive internal process for the feedback initialization is as follows:

Reads the position feedback.

Adds the origin to the feedback.

Determines modulo from Step 2 by the actual feedback bits.

Sets the position feedback sign according to FB1.INITSIGNED.
