8 Electrical Installation
8.1 Important notes
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 hints on page 41.
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.
l
The fusing of the AC supply input and the 24V supply is installed by the user (ð p.19).
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. Connect the shielding at both ends (ð p.47).
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 42.
l
Feedback lines may not be extended, since thereby the shielding would be interrupted and the
signal processing could be disturbed.
l
The cable between servo amplifier and regen resistor must be shielded.
l
Install all heavy-current cables with an adequate cross-section, as per EN 60204. (ð p.20)
and use the requested cable material (ð p. 42) to reach max. cable length.
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 It is permissible to alter the servo amplifier settings by using the setup software.
Any other alterations will invalidate the warranty.
Never disconnect the electrical connections to the servoamplifier while it is live. In
unfavorable 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
bus 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.
