2 Installation
2.1 Important notes
� Protect the servo amplifier from impermissible stresses. In particular, do not let any components
become bent or any insulation distances altered during transport and handling. Avoid
contact with electronic components and contacts.
� Check the combination of servo amplifier and motor (� p.72). Compare the rated voltage
and current of the units. Carry out the wiring according to the instructions on Page 26.
� Make sure that the maximum permissible rated voltage at the terminals for L1, L2, L3 and
+RBext, –DC is not exceeded by more than 10%, even in the most unfavourable conditions
(see EN 60204-1 Section 4.3.1). An excessive voltage on these terminals can lead to destruction
of the regen circuit and the servo amplifier.
Use the SERVOSTAR 44x only on an earthed 3-phase supply system. Use the amplifier only
to drive a synchronous servomotor.
� The fusing of the AC supply input and the 24V supply is installed by the user (� p.18).
� Take care that the servo amplifier and motor are properly earthed. Do not use painted
(non-conductive) mounting plates.
� Route power and control cables separately. We recommend a separation of at least 20 cm.
This improves the interference immunity required by EMC regulations. If a motor power cable
is used which includes cores for brake control, the brake control cores must be separately
shielded.
Earth the shielding at both ends (� p.28).
� Install all heavy-current cables with an adequate cross-section, as per EN 60204-1
(� p.18).
� Wire the BTB/RTO contact in series into the safety circuit of the installation.
Only in this way is the monitoring of the servo amplifier assured.
� Install all shielding with large area (low impedance) connections, with metallised connector
housings or shield connection clamps where possible.
Notes on connection techniques can be found on Page 32 and the Application Note “Cables
& Connectors”.
� Ensure that there is an adequate flow of cool, filtered air into the bottom of the switchgear
cabinet. Note the conditions on Page 18 .
� It is permissible to alter the servo amplifier settings by using the operator software.
Any other alterations will invalidate the warranty.
Caution
Never disconnect the electrical connections to the servo amplifier while it is live.
In unfavourable circumstances this could result in destruction of the electronics.
Residual charges in the capacitors can have dangerous levels up to 300 seconds after
switching off the mains supply voltage. Measure the voltage in the DC-link
(+RBext/-DC) and wait until the voltage has fallen below 40V.
Control and power connections can still be live, even when the motor is not rotating.
