Encoder evaluation
MOVIDRIVE
®
offers various options for positioning:
• external encoders
• Motor encoder (incremental encoder/resolver)
• Hiperface
®
encoder (absolute encoder)
• SSI absolute encoder
The values are provided in system variables for processing.
The connections for the motor encoder (X15) and external encoder (X14) are in the con-
trol electronics Mx
V
..., Mx
S
... und MC
H
... . The control electronics Mx
F
does not have
these connections. The connection for the SSI absolute encoder is on the DIP11 option
card (X62).
All connected encoders are always evaluated regardless of the operating mode (P700).
Operating modes with positioning (VFC-n-CTRL & IPOS, CFC & IPOS, SERVO & IPOS)
always require a motor encoder at X15.
