AKT2G-SM-L15 LEDs & Connections

WARNING! Risk of electric shock and damage of devices possible!

Bring the bus terminal system into a safe, powered down state before starting installation, disassembly or wiring of the Bus Terminals!

LEDs

No.	LED	Color	Meaning
1	RUN	green	This LED indicates the terminal's operating state:
			off	State of the EtherCAT *EtherCAT 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
			blinking	State of the EtherCAT State Machine: PREOP = Setting for mailbox communication and variant standard settings
			single flash	State of the EtherCAT State Machine: SAFEOP = Channel checking of the Sync Manager and the Distributed Clocks. Outputs stay in safe operation mode.
			on	State of the EtherCAT State Machine: `OP` = Normal operation mode, mailbox- and process data communication possible
2	Encoder	green	on	Encoder ready for operation
3	A	green	on	Signal at encoder input A
4	B	green	on	Signal at encoder input B
5	C	green	on	Signal at encoder input C
6	Latch	green	on	Signal at latch input
7	Turn CW	green	on	Motor is triggered clock wise
8	Input 1	green	on	Signal at digital input 1
9	Driver	green	on	Driver stage ready for operation
10	Power	green	off	The power supply voltage (24 VDC) is absent or the motor control is blocked (Index 6010:02] is not set))
10	Power	green	on	The power supply voltage (24 VDC) is present
11	Warning	yellow	on	Configuration error, e.g.: Motor power supply not connected 80°C temperature exceeded 100% duty cycle reached ...
12	Error A	red	on	Configuration error of output stage A, e.g.: 100°C temperature exceeded short circuit ...
13	Error B	red	on	Configuration error of output stage B, e.g.: 100°C temperature exceeded short circuit ...
14	Enable	green	off	The motor control is blocked (Index 6010:02] is not set) or SM-L15 is not ready for operation
14	Enable	green	on	The motor control is activated (Index 6010:02] is set) or SM-L15 is ready for operation
15	Turn CCW	green	on	Motor is triggered counter clock wise
16	Input 2	green	on	Signal at digital input 2

Terminal Points

Terminal point	Name	Signal
1	A	Encoder input A
2	C	Encoder input C (zero input). If object 7000:01 is set in the control word and a rising edge A rising edge is the transition of a digital signal from low to high. It is also called positive edge occurs at encoder input C, the current counter value is stored as a reference mark in the latch register.
3	Encoder supply +24V	Encoder supply + 24 V, internally connected with positive power contact and pin 6, 7
4	A1	Motor winding A1
5	B1	Motor winding B1
6	+24V	+24 V_DC, internally connected with positive power contact and pin 3, 7
7	+24V	+24 V_DC, internally connected with positive power contact and pin 3, 7
8	Input 1	Digital input 1 (24 V_DC)
9	B	Encoder input B
10	Latch The 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	Latch input. The current counter value is stored as a reference mark in the latch register, if object 7000:02 is set and a rising edge occurs at the latch input; or object 7000:04 is set and a falling edge occurs at the latch input.
11	Encoder supply 0V	Encoder supply 0 V, internally connected with negative power contact and pin 14, 15
12	A2	Motor winding A2
13	B2	Motor winding B2
14	0V	0 V_DC, internally connected with negative power contact and pin 11, 15
15	0V	0 V_DC, internally connected with negative power contact and pin 11, 14
16	Input 2	Digital input 2 (24 V_DC), also configurable as a digital output (0,5 A)
