Note:
The inputs on the control must not be assigned any signals other than the intended sig-
nals. Otherwise, sporadic or permanent malfunction or damage can occur.
It is especially important for spindle applications, that possibly available signals from
additional temperature sensors (PTCs, NTCs or similar) must NOT be connected to the
CP–, CN–, DP–, DN inputs that are not used when using induction motors!
When ”parking axis” is selected, the encoder can be withdrawn and inserted also under
voltage.
