Note
Short-term voltage dips in the external 24 V supply (≤ 3 ms and ≤ 95% of the rated voltage)
When the mains voltage of the inverter is switched off, the inverter responds to short-term
voltage dips in the external 24 V supply with fault F30074. Communication via fieldbus,
however, remains in effect in this case.
Permissible encoder cable lengths
Permissible cable lengths depend on the encoder type and the encoder cable.

TTL encoder
HTL encoder with bipolar signals (differential signals)
HTL encoder with unipolar signals
SSI encoder
DRIVE-CLiQ with MC800
DRIVE-CLiQ with MC500
We recommend that SIEMENS cables are connected using DRIVE-CLiQ components.
For SSI encoders, the permissible
cable length also depends on the
baud rate.
