Encoder power supply, either 15 or 24 V DC (according
to jumper selection on terminals 4, 5 and 6).
(0 V is also used with single-ended encoder connection
for balancing the A+, B+ and/or Z+ conductors. See

Encoder supply voltage selection:
Terminals 4 and 5 connected: 15 V (default)
Terminals 5 and 6 connected: 24 V
(Jumper is supplied with the RTAC module)

• Max. signal frequency: 200 kHz
A
• Signal levels:
A
"1" > 7.6 V, "0" < 5 V (for 15 V supply)
"1" > 12.2 V, "0" < 8 V (for 24 V supply)
