5.15 Power feedback unit connection
CAUTION!
Caution!
In devices of the ZETADYN 3C type only the connecting DC (red) and R (blue) are connected
to the connection terminal X2! If a power feedback unit is used, the
blue wire
must be rewired from the
connection terminal
R
to the connection terminal
-DC
on the internal ZETADYN 3BF.

X-ENC9:
9-pole SUB-D jack for connection with Sub-D plug
X-ENC15:
15-pole SUB-D jack for connection with Sub-D plug
X-ENC8:
8-pole terminal strip for connection with single wires
Information
When operating the motor with a sinusoidal or incremental encoder, the frequency inverter must be
equipped with the option module EM3-ENC-ASM-ZA (item no. 357104)
• Use a shielded cable for the connection.
• Attach the shielding on the inverter corresponding to the terminal or pin assignments.
•
Make the connection between the frequency inverter and the encoder without additional terminal
points.
CAUTION!
Caution!
The SUB-D jack pin assignments are not standardized. When using external encoders, make
sure that they have the identical contact assignments and an interface with identical speci
fi ca-
tions.
CAUTION!
Caution!
Before the encoder is plugged on/connected, the encoder type and resolution used must be
con
fi
gured in the menus
"Encoder & BC/ENC_TYP"
and
"Encoder & BC/ENC_INC "
.
