App. 5.8.2 Interfaces
In this servo amplifier, source type I/O interfaces can be used.
(1) Sink I/O interface (CN9, CN10 connector)
(a) Digital input interface DI-1
This is an input circuit whose photocoupler cathode side is input terminal. Transmit signals from sink
(open-collector) type transistor output, relay switch, etc.
Pin
No.
3A
Connect this device to a safety switch for A-axis driving device.
3B
Input the same signal as A-axis shutdown 1.
STO state (base shutdown): Open between SDI2A+ and SDI2A-.
STO release state (in driving): Close between SDI2A+ and SDI2A-.
4A
Connect this device to a safety switch for B-axis driving device.
4B
Input the same signal as B-axis shutdown 1.
STO state (base shutdown): Open between SDI2B+ and SDI2B-.
STO release state (in driving): Close between SDI2B+ and SDI2B-.
1A
Signal for releasing STO state (base shutdown) on A-axis driving device.
1B
Releases STO state (base shutdown) on A-axis driving device by switching between
SRESA+ and SRESA- from on (connected) to off (opened).
2A
Signal for releasing STO state (base shutdown) on B-axis driving device.
2B
Releases STO state (base shutdown) on B-axis driving device by switching between
SRESB+ and SRESB- from on (connected) to off (opened).
6A
Outputs STO2 to A-axis driving device.
6B
Outputs the same signal as A-axis STO1.
STO state (base shutdown): Between SDO2A+ and SDO2A- is opened.
STO release state (in driving): Between SDO2A+ and SDO2A- is closed.
5A
Outputs STO2 to B-axis driving device.
5B
Outputs the same signal as B-axis SDO1.
STO state (base shutdown): Between SDO2B+ and SDO2B- is opened.
STO release state (in driving): Between SDO2B+ and SDO2B- is closed.
7A
Connect + side of 24 V DC.
7B
Connect - side of 24 V DC.
8A
TOFA is internally connected with TOF2A.
8B
TOFB is internally connected with TOF2B.
