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	520Dh/0	M_01-00-00-000

Description

EMU Encoder Out PulseWhen the step gets activated, the action is activated for a single execution, and possibly once again when the step is deactivated Width Register

Sets pulse width for CW/CCW and Step and Direction modes. This parameter does not effect the A quad B mode. To calculate emuOutPulseWidth:

(Desired pulse width -40 nsec)/520 nsec

Requirement		DSFPGA-03-306
Bits	Bits	Description
11:0	emuOutPulseWidth	Read/Write 12 bit unsigned number minimum resolution is 520 nsec. ResetNew start of the microprocessor state – 0
15:12		reserved

Register is in counts (12 bit)

Register * 520ns + 40ns is the actual pulse with.

Register = 1 = pulse width is 560ns = 0.56us (minimum value)

For each register increment the pulse width is raised by 0.52us

Example

50 usecs pulse width

emuOutPulseWidth = (50 usecs – 40 nsec)/520 nsec = 96

actual pulse = 96*520 nsec + 40 nsec = 49.88 usecs.
