2.1 Important instructions
l
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.
l
Check the combination of servo amplifier and motor. Compare the rated voltage and current of
the units. Carry out the wiring according to the connection diagram on page 28.
l
Make sure that the maximum permissible rated voltage at the terminals L1, L2, L3 or +DC,
–DC is not exceeded by more than 10% even in the most unfavorable case
(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 600
servo amplifiers only on an earthed (grounded) 3-phased supply system, to drive a synchro
-
nous servomotor.
l
The fusing of the AC supply input and the 24V supply is installed by the user (ð p.18).
l
Take care that the servo amplifier and motor are earthed (grounded) properly. Do not use
painted (non-conductive) mounting plates.
l
Route power and control cables separately. We recommend a separation of at least 200mm.
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 (ground) the shielding at both ends (ð p.30).
l Install all heavy-current cables with an adequate cross-section, as per EN 60204. (ð p.19).
l 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.
l Install all shielding with large areas (low impedance), with metallised connector housings or
shield connection clamps where possible. Notes on connection techniques can be found on
page 33 and in the application note “Cables and connectors”.
l Ensure that there is an adequate flow of cool, filtered air into the bottom of the switchgear ca-
binet. Observe page 19 .
l It is permissible to alter the servo amplifier settings by using the setup software.
Any other alterations will invalidate the warranty.
Caution
Never disconnect the electrical connections to the servoamplifier while it is live. In un
-
favorable 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 bus voltage at the DC-link pins
(+DC/-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.
