2.2.8 Resolver to Encoder (optional)
For position sensing a resolver to encoder option (simulated encoder) is available.
Encoder signals are 7V, 100
Ω
impedance, as follows:
•
2 channels of square wave output with a resolution from 128 to 1024 pulses per electrical
revolution. Channel B leads channel A by 90
°
for clockwise rotation when viewed from
shaft end.
•
1 marker pulse per electrical revolution (i.e. 1
∗
3 = 3 marker pulses per mechanical
revolution with a 6 pole resolver).
•
complementary outputs A, B and C .
