Process image

Process image 1:

In the default setting the EP8309 is configured for:

  • analog input channel 1
  • analog input channel 2
  • Tacho signal from two sensors on one axis (single-shaft mode)
  • 6 digital inputs
  • Status of PWM output
  • Acknowledge / Reset in the event of a PWM error.
  • 6 digital outputs
  • General EtherCAT process data

AI Inputs Channel 1 and 2

Process image 2:

The data for the first analog channel can be found under AI Inputs Channel 1.

 

Underrange: Value of the analog input is less than 0/4 mA or -10/0 V
Overrange: Value of the analog input is greater than 20 mA or +10 V

Limit 1: with activated Limit 1 (object 0x8000:07 = 1) means
1: value less than limit 1 (set in object 0x8000:13)
2: value greater than limit 1 (set in object 0x8000:13)
3: value equal to limit 1 (set in object 0x8000:13)

Limit 2: with activated Limit 2 (object 0x8000:08 = 1) means
1: value less than limit 2 (set in object 0x8000:14)
2: value greater than limit 2 (set in object 0x8000:14)
3: value equal to limit 2 (set in object 0x8000:14)

Error: This bit is set if over- or under-range was detected. 

Tacho single-shaft mode (depending on the setting in the PDO assignment)

Process image 3:

The data for the tacho input can be found under TACHO Single Shaft Mode Input Channel 1.

see data under commissioning

Tacho dual-shaft mode (depending on the setting in the PDO assignment)

Process image 4:

The data for the tacho input can be found under TACHO Dual Shaft Mode Input Channel 1 or 2.

see data under commissioning

DIG Inputs

Process image 5:

The data for the digital inputs can be found under DIG Inputs.

X4 Pin4 -> socket 4, pin 4

....

PWM Status

Process image 6:

The data for the PWM output can be found under PWM Status

DEV  Inputs

Process image 7:

The diagnostic data for the two voltages Us and Up can be found under DEV Inputs.

TRUE = voltage <= approx. 18 VDC

....

TACHO Output Channel 1

Process image 8:

The control data for the tacho input can be found under TACHO Output Channel 1.

Reset Error - error reset

DO Outputs

Process image 9:

The data for the digital outputs can be found under DO Outputs.

X5 pin4 -> socket 5, pin 4

....

PWM control (activated through PDO assignment 0x1602, default PWM, alternatively AO)

Process image 10:

The control data for the PWM output can be found under PWM Control.

Enable Dithering -> activate dithering

Enable -> activate PWM output

Reset -> reset on error

PWM output -> load-independent current, depending on module rating (e.g. 1.2 A and setting in object 0x8050:10)

AO outputs (activated through PDO assignment 0x1603), not activated by default

Process image 11:

The values for the analog output can be found under AO Outputs.

Analog Output - output value
