Connection


  • Encoder supply via the terminal

    The encoder supply voltage (5 V), can be taken from the terminal point 1’.

Terminal Point No. Comment
A 1 Encoder input A
B 2 Encoder input B
C 3 Encoder input C
LatchClosedThe control word is used to activate the drive's latch status machine. The latch control word is processed independently of the EtherCAT bus cycle. The status word is used to return the drive's latch status 24 V 4 Latch input
¬A 5 Encoder input A
¬B 6 Encoder input B
¬C 7 Encoder input C
Gate 24 V 8 Gate input
Ue = +5 V 1' +5 V encoder supply
+24 V 2' +24 V (internally connected to terminal point 6' and positive power contact)
0 V 3' 0 V (internally connected to terminal point 7' and negative power contact)
Input 1 4' Status input 1
Alarm input from rotary encoder. Internally connected to 5 V via pull-up. Switching to negative potential, i.e. connection to GND leads to error bit and LED display. If externally supplied (not recommended) 5 V max. against GND is permitted.
Uo = 0 V 5' 0 V encoder supply
+24 V 6' +24 V (internally connected to terminal point 2' and positive power contact)
0 V 7' 0 V (internally connected to terminal point 3' and negative power contact)

LED Color Meaning

LED

Color

Meaning

INPUT A, B, C

green

indicates TRUE level

INPUT 1

red

is lit, if INPUT 1 is connected to GND

[INPUT 1 is connected to an internal 5 V HIGH level though internal pull-up (default)]

LATCH

green

is lit, if a signal (+24 V) is connected to the latch input

GATE

green

is lit, if a signal (+24 V) is connected to the gate input

RUN

green

This LED indicates the terminal's operating state:

off

State of the EtherCATClosedEtherCAT 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 State Machine: INIT = initialization of the terminal or BOOTSTRAP = function for firmware updates of the terminal

    

flashing

State of the EtherCAT State Machine: PREOP = function for mailbox communication and different standard-settings set

    

single flash

State of the EtherCAT State Machine: SAFEOP = verification of the Sync Manager channels and the distributed clocks.

Outputs remain in safe state

    

on

State of the EtherCAT State Machine: OP = normal operating state; mailbox and process data communication is possible
