Motor phase failure - power section
• This error message is displayed if a motor phase
carries less current of one half-wave than set in
.
• Check the motor connections and the corresponding
plug connector on the device and, if necessary, the
motor terminal box.
• Check the trigger threshold (
).

• HTL encoder cable interrupted.
• HTL encoder is defective.
Note: The reason can also be a very dynamic acceleration
or an approach against a blocked motor shaft, e.g. with a
a closed holding brake or when referencing to positive
stop (mode 14/15) and a waiting time (
)
>100 ms.
• Check HTL encoder cable.
• Check HTL encoder.
• Check related terminals.
• Switch off monitoring (
= "0: No reaction")
when the HTL encoder is not used.

Starting from version 15.00.00,
Sd15 is tripped if, due to
different signal levels (quadruple evaluation of the
digital inputs), an open circuit is detected. The quadruple
evaluation is activated if "4: encoder signal FreqIn1256"
is selected as speed or position encoder (
• Check HTL encoder cable.
• Check HTL encoder.
• Check wiring of the input terminals for open circuit or
loose contact.
