Characteristics of digital high speed input
Characteristic
Description
Number of digital outputs
2: FastOut0 and FastOut1
Function
External stepper drive control (
1
)
High speed state output
High speed pulsed output
High speed PWM output with on delay
Type of load
Only resistive or capacitive loads are supported.
The fast digital output cannot be used for inductive
loads.
Grounded load
Yes, (high side switching outputs)
Galvanic insulated
Yes
Switch time (
2
)
< 2 μs (with load current ≥ 50 mA)
Short circuit protected
Yes, single PTC fuse for both outputs
Fail / no load detection
No
Voltage supply
24 V ±6 V
Output current
0.4 mA ... 100 mA, typical is 50 mA
1
Active high control signals are recommended. Using active low
control signals is only possible if the minimum input level speci‐
fied by the external stepper drive is higher than 0.7 V.
2
Indicated time only apply with a resistive load. Indicated time
changes if the load has a capacitive component.
