* This is a differential line according to RS422/RS485 standards

** This is a 5 V supply that can provide up to 250 mA for external use.

The supply is protected against short to ground and keeps the current below 400 mA in a continuous short.

* This is a differential line according to RS422/RS485 standards

** This is a single-ended TTL line with 1 kOhm pull-up resistors

*** This is a 5 V supply that can provide up to 250 mA for external use.

The supply is protected against short to ground and keeps the current below 400 mA in a continuous short.

All Digital IOs are 3.3 V LVTTL CMOS logic and can be used for data rates up to 20 Mbps.

* This is a +3.3 V supply that can provide up to 250 mA for external use.

The supply is protected against short to ground and keeps the current below 400mA in a continuous short.

** Can be configured as 5.0 V CMOS logic. Upon request only, please contact sales@synapticon.com

*** This is a +5 V supply that can provide up to 250 mA for external use.

The supply is protected against short to ground and keeps the current below 400mA in a continuous short.

Note

Each Digital IO needs to be configured as a Digital Input or Output via object 0x2210 (“GPIO”).

The object can also be used to activate a pull-down resistor.

Changes may require to powercycle the servo drive.

Analog IN

Pin #		Default Setting *
1	–
2	Analog Input 1 -	Connect to Ground **
3	Analog Input 1 +	Single-ended 0-10 V
4	Ground
5	Analog Input 2 -	Connect to Ground **
6	Analog Input 2 +	Single-ended 0-10 V
7	5 V ***
8	10 V ****
9	Analog Input 3 -	Differential ±5 V
10	Analog Input 3 +	Differential ±5 V
11	Analog Input 4 -	Differential ±5 V
12	Analog Input 4 +	Differential ±5 V

* All Analog Inputs can be configured as single-ended 0-5 V, 0-10 V, 0-20 V or differential ±5 V, ±10 V independently.

Upon request only, please contact sales@synapticon.com

** Must be connected to Ground when the Analog Input is set to Single-Ended Mode.

It is recommended to use a separate ground cable for each single-ended analog signal/cable and twist or tie them together.

*** This is a 5 V supply that can provide up to 100 mA for external use.

The supply is protected against short to ground and keeps the current below 400mA in a continuous short.

**** This is a 10 V supply that can provide up to 25 mA for external use.

The supply is protected against short to ground and keeps the current below 100mA in a continuous short.
