NOTE
If there are deviations from the standard equipment (A.772.4) for the motors, please note the
accompanying data sheet or consult your supplier.
RECOMMENDATION: For greater reliability, in particular with long connection cables, we recommend the use of a higher
power supply (15V/24V) and an incremental encoder for 10-30V power supply. The signal level must
still be 5V TTL.
ATTENTION
The rotation field of the incremental encoder must correspond to that of the motor. Because of
this, according to how the encoder is mounted on the motor (possible mirror image), tracks A+
and A- may need to be switched over or a negative sign entered in parameter P301. For
SK 750E, inverted mounting has already been taken into account!
