Digital High Speed Inputs and Outputs

3. Connect the NYCe 4000, a power supply or other equipment on a metal
frame or mounting base and make sure there is a galvanic contact.
4. A fuse must be installed between the +24 V power supply and 24V_DIO
on the node. The fuse is mandatory by safety regulations and must be
UL recognized. See NYCe 4000 Standard Housings and Accessories
manual for detailed information about fuses.
5. If the load represents a high impedance input, you must use an external
pull down resistor to meet the minimum specified output current through
the switch.

NY4125: 5-axis low power PWM Drive Module
Description
2: FastIn0 and StopAlarm
● FastIn0
– High speed general purpose digital input
– High speed position latching
– Change of state event (1 per MCU's
sample time)
– Count transitions (max. frequency 250
kHz)
● StopAlarm for the drive module (all axes)
In less than 10 µs the upper FETs are open and
the lower FETs of the bridges are closed to
create a short circuit of the motor coils (fastest
stop of the motor).
The StopAlarm input is default configured high
active.
No, always grounded load (high side switching)
