Connecting a pulse transmitter/incremental encoder
Inputs I1 to I4 are designed so that high-speed signals from pulse
transmitters/incremental encoders can be counted.
The following connection options are possible:
• 1
x
pulse transmitters (32-bit)
• 2
x
pulse transmitters (16-bit)
• 1
x
incremental encoder (32-bit).
Connecting pulse transmitter
The figure shows the connection of a pulse transmitter which
sends pulses to input I1. An internal counter processes the pulses.
You can choose between a 16-bit counter (max. 65535) and 32-bit
counter (max. 4294967295). The pulse transmitter for the 32-bit
counter must only be connected to I1. Only if a 16-bit counter was
used at I1, can another pulse transmitter (32-bit) be connected to
I2.
