Information
Calculation example – Maximum frequency f
max
for an encoder with 2,048 pulses per revolution: 3,000 revolutions per minute (equivalent to 50 revolutions per second) *
2,048 pulses per revolution = 102,400 pulses per second = 102.4 kHz << 1 MHz
Information
Using an HT6 adapter for level conversion from HTL signals to TTL signals, it is also possible to connect a differential HTL
incremental encoder to terminal X4. Note that, with an external power supply, the maximum level of 20 V
DC
for the HTL
signals may not be exceeded.
