Installation and Connection

2.2.2 Connection of the control circuit

In order to prevent a malfunction caused by interference voltage supply on the control inputs, the following
directions should be observed:
•
Use shielded / drilled cables
•
Lay shield on one side of the inverter onto earth potential
•
Lay control and power cable separately (about 10...20 cm apart); Lay crossings in a right angle (in
EMC
case it cannot be prevented)

2.2.3 Digital Inputs

13...30 V DC ±0 %
stabilized
Ri = 2,1 kΩ

2.2.4 Analog Inputs

Connect unused analog inputs to common, to prevent set value fluctuations !
Analog set value setting in speed regulated operation (CP.10 = 4):
Ri = 55 k�

0...±10 VDC
Analog set value setting in torque regulated operation (CP.10 = 5) and reference source CP.28 = 1:
*) Connect potential equalizing line only if a potential difference of >30 V exists between the controls.
The internal resistance is reduced to 30 kΩ.
