Inputs for SinCos encoders and PTC (15-pin female connector HD-Sub-
D)
The encoder interface is designed for connection of standard commercial SinCos (op-
tionally with commutation tracks for synchronous motors), EnDat 2.1 (SinCoS trac
required), Hiperface and SSI encoders (optionally with TTL [RS-422] or SinCos track).
Depending on the encoder type, different signals are evaluated. The following signals
can be evaluated:
- A/B tracks and/or Sin/Cos tracks
- C/D tracks (commutation tracks) or Data/Clock tracks (absolute value encoders)
- R tracks (reference track)
- Measuring line for monitoring and control of encoder supply voltage
Input: sinusoidal incremental signals, internal resistance of source <100 Ω,
/B and C/D tracks: Direct portion V
=DC 2.5 V ±0.5 V, peak value: 0.6 V,
R-track: Direct portion V
=DC 2.5 V ±0.5 V, differential voltage: 1.8 V.
The encoder supply voltage at contacts X412.6 (V
Enc
) and X412.15 (0VL) can be ad-
usted throu
h parameter Supply voltage 1187 in between DC 5.0 … 12 V. See chap-
ter 8.4.4 “Supply voltage”. Max. load: 2 W.
PTC input:
Trigger resistance = 2.4 kΩ (PTC) as per DIN 44081,
PTC or bimetal temperature sensor (NC)
Use PTC resistors with safe isolation from motor winding according to EN 61800-5-1.
