tion instructions
•
Max. line length inverter - encoder: 100 m with a capacitance per unit length
≤
120 nF/km.
•
MCV/MCS4_A: Conductor cross section 0.20 ... 0.5 mm
2
(AWG 24 ... 20)
•
MCH4_A: Conductor cross section
– Hiperface
®
encoders, sin/cos encoders and TTL sensors with DC 5 V supply (via
DWI11A): 0.25 ... 0.5 mm
2
(AWG 23 ... 20)
– TTL encoder with DC 12 ... 24 V supply: 0.5 mm

(AWG 20)
•
If you cut a core of the encoder cable, isolate the cut-off end of the core.
•
Use shielded cables with twisted pair conductors and make sure they are grounded
on both ends over a large surface area:
– At the encoder in the cable gland or in the encoder plug
– At the inverter in the housing of the Sub-D connector and at the electronics shield
clamp of the inverter
•
Use an encoder connector and Sub-D connector with metal housing.
•
Route the encoder cable separately from the power cables.
•
Encoder with cable gland: Observe the permitted diameter of the encoder cable to
ensure that the cable gland functions correctly.
Shielding
Connect the shield of the encoder/resolver cable over a large area.
On the inverter
Connect the shield on the inverter end in the housing of the sub D connector (
→
follow-
ing illustration).
NOTE
The wiring diagrams do now show the view onto the cable end. They show the connec-
tion to the motor or MOVIDRIVE
®
.
The core colors specified in the wiring diagrams are in accordance with the IEC 757
color code and correspond to the core colors used in the prefabricated cables from
SEW.
