What is the B&R 8AC125.60-1?

BiSS encoder interface (Mode C) for installation in ACOPOS servo drives

Encoder supply 5 V

Encoder monitoring

ACOPOS plug-in module, BiSS/SSI SinCos/SSI interface

Specifications

General information

Certifications – CE	Yes
Certifications – UKCA	Yes
Certifications – CRA (Cyber Resilience Act)	Non-compliant
Certifications – UL	cULus E225616; Power conversion equipment
Certifications – KC	Yes
Module type	ACOPOS plug-in module
B&R ID code	0xACF3
Slot	Slots 2, 3 and 4 (note: The AC125 is an encoder module. It is also possible to connect multiple encoder modules. In this case, the encoder module in the smallest slot automatically serves as motor feedback.)
Power consumption	Max. 4.5 W

Encoder inputs

Electrical isolation – Encoder - ACOPOS	No
Encoder power supply – Output voltage	Typ. 5 V
Encoder power supply – Load capacity	250 mA
Encoder power supply – Sense lines	Yes
Sine/Cosine inputs – Signal transmission	Differential signals, symmetrical
Sine/Cosine inputs – Signal frequency (-3 dB)	DC up to 300 kHz
Sine/Cosine inputs – Signal frequency (-5 dB)	DC up to 400 kHz
Sine/Cosine inputs – Differential voltage	0.5 to 1.25 V SS
Sine/Cosine inputs – Common-mode voltage	Max. ±7 V
Sine/Cosine inputs – Terminating resistor	120 Ω
Sine/Cosine inputs – Resolution	16384 * Number of encoder lines (note: Depending on the resolution of the connected encoder, only part of this resolution can be used in practice. In addition, the usable resolution can be reduced by signal noise of the connected encoder.)
Sine/Cosine inputs – Accuracy	- (note: In practice, the accuracy is limited by the encoder.)
Reference input – Signal transmission	Differential signal, symmetrical
Reference input – Differential voltage for low	≤-0.2 V
Reference input – Differential voltage for high	≥+0.2 V
Reference input – Common-mode voltage	Max. ±7 V
Reference input – Terminating resistor	120 Ω
Serial interface – Signal transmission	Synchronous
Serial interface – Protocol	RS485
Serial interface – Baud rate	Depends on the configured functionality
Quantity	1
Module-side connection	15-pin female DSUB
Status indicators	UP/DN LEDs
Encoder monitoring	Yes
Max. encoder cable length	50 m (note: Requirement: Wiring of the encoder takes place with a shielded cable with a wire cross section of min. 0.14 mm² for all signal lines and a wire cross section of min. 0.5 mm² for all encoder power supply lines.)

Ambient conditions
