Illustration 26: Y30/Connecting Power and Differential Encoder Signals to TTL Encoder (VLT® Safety Option MCB 150)
The TTL encoder in
illustration 26 is shown with 24 V supply and TTL output. If an encoder for 5 V supply must be connected, use a 5 V
external supply.
4.2.3 Proximity Switch
An inductive proximity switch, detecting already present mechanical parts, for example a gear wheel, is a frequently used alternative to
standard encoders. The required minimum number of pulses per revolution (PPR) is 2 on the motor shaft while considering the gear
ratio.
