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.
