Wiring Instructions

6.1General Information

Digital servo drives are designed for operation in metallic grounded enclosures.

For perfect operation as well as for observance of all regulations the front board must be connected with the enclosure electrically and fixed.

6.2Control cabling

Recommended cross section 0,25 mm².The control signal lines must be laid seperate from the power signal lines.(see chapter 6.7.1)

The resolver cable must contain three shielded pairs and must be shielded as a whole. The shielding should be connected to the ground spread out on the regulator side. We recommend using SSD Drives resolver cable KIR. Cable for transmitting data are always to be laid shielded !

6.3Power cabling

Recommended section according to rated current. Use only 75° Cu-cables.

6.4Installation of the rack

When the rack is secured not in a hinged bay but on a mounting plate, it is recommended to do the wiring of the connections for the power connector X50 on the rear of the rack before installing. With hinged-bay installation, the customer must ensure that the parts sensitive to voltage such as the Ucc bus, mains supply lines, etc., are protected against electric shock.

6.5Analog setpoint

The setpoint input is a differential input. Therefore the poling can be done depending on the requirements. Important: the setpoint voltage must be galvanically connected to the reference potential of the control connections (plug X10). It is possible to connect one pole directly to GND.

6.6Safety rules

Caution !

Plug / unplug all modules only when

Ucc (DC-BUS) is off, that is, the green LED on the power supply module is off and the discharge time > 3 minutes has elapsed.

The user must ensure protection against accidental touching.

6.7Electromagnetic compatibility (EMC)

Confirmity in accordance with the EEC Directive 89/336/EEC has been evaluated using a reference- system, consisting of a compact type drive and a line-filter on mounting-plate,

connected to an AC-syncronous motor.

Mainly responsible for EMC-emissions is the motor cable. So this has to be installed exeptional carefully. The layout of grounding is very important. Grounding has to be low-impedant for high frequences. That means, all ground-connecting parts have to use area.

The measurements made are valid under the use of SSD Drives - cables, suppression aids and line filters and by application of the following wiring instructions:
