PARAMETER ALLOWABLE RANGE DEFAULT DESCRIPTION
Sine/Cosine Encoder This menu is Context Enabled: It is visible when Type = Sine/Cosine Encoder
Note, the sin/cos sensor physical waveforms are not bipolar, but center around an offset voltage, typically around 2.5v. The Peak-Peak voltage
swing may be as small a 1volt or up to 2.5 volts. If the sensor voltages go outside this range, position sensing will be faulty and not useable by the
VCL functions. In this case, a fault will be detected.
Sin Min Voltage

50 – 450
3.00
300
The highest voltage that the cosine waveform normally
reaches.

reaches.
X = 1 or 2 for the Type: Cos_X_Min
Saw Encoder This menu is Context Enabled: It is visible when Type = Saw Encoder
Sawtooth Max/Min voltage signal: If this analog signal goes outside the specied ranges for >60ms, a fault is declared.

channel A.
X = 1 or 2 for the Type: Saw_Enc_X_Offset
If the position calculated using the channel A is outside
a tolerance parameter compared to that of channel B for
>60ms, a fault is declared
