Pulse interface
Note
All signals are PELV (protected extra low voltage) signals as defined by
VDE 0160.
Pulse interface inputs
PULSE (clock), DIR (sense of rotation), ENABLE (power controller
enable),
PWM (current control). For a signal description, see chapter 4.
5 V optocoupler inputs:
Voltage control:
U
high, min
= 2.5 V
U
high, max
= 5.25 V
U
low, max
= 0.4 V
U
low, min
= -5.25 V
I
max
= 30 mA
Current control:
I
high, min
= 7 mA
I
high, max
= 25 mA
I
low, max
= 0.2 mA
I
low, min
= -25 mA
U
max
= 5.25 V
Note
It is recommended to use push-pull control for reasons of noise
suppression.
Uce
GND_S
Pulse interface output
READY1_N (readiness). For a signal description, see chapter 4.
Optocoupler output (no reverse-polarity protection, not short-circuit
protected):
Uce:
30 V max.
Uce,sat:
< 1.0 V at 10 mA
!
Warning
This output is not short-circuit protected and does not feature reverse-
polarity protection.
GND_S:
System ground, internally connected
