15 / 56
Parameters
Description
Use as input
PNP input or NPN input
NPN and PNP input
Switching the interface to NPN or PNP affects the
entire PWM_H7_x group!
L level ≤ 1.6 V
H level ≥ 4.6 V
Input resistance
PNP 94 kΩ
NPN 10 kΩ
Tab. 12:
Outputs PWM_H7_1 ... PWM_H7_6
INFO
Measurability of very short pulses
The duty cycle at the PWM output has a resolution of 0.1%. Due to the limited
edge steepness, very short pulses may not be measured.
■
Example - high frequency pulses:
At 10 KHz output frequency and 0.1% or 99.9% duty cycle and low imped-
ance load, a signal can no longer be measured.
■
Example - low frequency pulses:
At 1 Hz output frequency 0.1% duty cycle can be measured.
