FEN 31 Speed Detection Operation
X5
81 Output: channel A
Setpoint pulses for slave
(5 V - TTL, RS-422)
not required for slave(s)
82 Output: channel A
83 Output: channel B
84 Output: channel B
85 Output: channel C
86 Output: channel C
87 Reference potential for terminals
X6
88 Input: channel A
Connecting encoder
The A
→
B channel sequence means:
motor runs clockwise
(as seen from motor output shaft end),
i. e. channel A leads channel B when the fan
rotates counter-clockwise
89 Input: channel A
90 Input: channel B
91 Input: channel B
92 Input: channel C
93 Input: channel C
94 Encoder power supply (+ 5...8 V)
For measuring voltage on encoder (if sensor leads
are not connected, then leave TLs 95 and 96 open)
95 Sensor line (+ 5 V)
96 Reference potential of terminal 95
97 Reference potential of terminal 94
