Prior to pressing the “ON” button on the MTB panel:
1. Check all wiring connections, both electrical and fiber optic. Make
sure inter-module connections correspond to the system wiring
diagram covered starting on page 7A-1. Make sure grounding is
adequately wired as directed on page 4D-10. If absolute encoders are
used make sure the battery for absolute feedback is connected.
2. Check the external ac power supply. Make sure it will supply
115/230 V ac to the main power supply. Also test that the servo
amplifiers are receiving proper voltage. If an analog servo system is
being used refer to the manufactures documentation for amplifier
power requirements. If a digital servo system is being used, the 8520
servo amplifiers should be receiving 3
Æ 220-240 V ac, and the 1394
or 9/440 system should be receiving 3 Æ 380 or 460 V ac.
3. Turn “ON” the circuit that supplies the external ac power. Do not
push the power “ON” button on the MTB panel. Make sure the ac
POWER indicator located on the front top of the main power supply
is illuminated.
4. Make sure the E-Stop button is depressed.
5. Check the terminal block connections and the jumper settings of the
servo amplifier. For an analog system refer to drives documentation
provided by the manufacturer. For a digital system check against the
terminal block connection and jumper setting tables starting on page
13A-1 (for 8520 drives), 11A-1 (for 1394 drives),
or 5A-28 (for 9/440 CNCs).
6. Check the incoming ac for logic power to the servo amplifiers. For
an analog system refer to documentation provided by the drives
manufacturer. For a digital drive system, verify that the voltage listed
below is present at the following terminals of the servo amplifier
using a volt meter:
8520 Drives
TB1-4 to TB1-5
170 to 253 V ac
The 8520 digital servo amplifier circuit board contains a green
SYSTEM READY indicator light and a yellow BUS UNDER
VOLTAGE indicator light. Both of these indicators should be
illuminated. The SYSTEM READY indicator light indicates that
the servo amplifier is receiving logic power. The BUS UNDER
VOLTAGE indicator light indicates that 3
Æ 230 V ac motor power
is not present at the TB1 terminal block.
