Replacement Procedures
15B-40
To replace a digital servo amplifier:
1. Turn OFF all power to the control and the servo amplifier.
ATTENTION: To guard against electrical shock hazards, never
make connections or disconnections at the ac distribution
network unless the main ac disconnect switch is open and
locked.
2. Carefully disconnect and mark all cables that are connected to the
servo amplifier.
3. Loosen but do not remove the 4 mounting screws that hold the servo
amplifier to the cabinet.
4. Grasp the servo amplifier firmly with one hand holding the chassis
under connector TB1 and one hand holding the chassis just to the
right of TB2.
5. Carefully slide the servo amplifier up (mounting holes are slotted)
and then out.
6. Install the replacement amplifier by reversing the removal procedure.
Grasp it as described in step 4 above and position it over the
mounting screws.
7. Carefully slide it down, making sure all four screws are positioned
into the screw slots.
8. Tighten the four mounting screw securely.
9. Replace all wires and connectors exactly as they were removed.
10. MATCH JUMPERS on the new servo amplifier to the settings on the
amplifier being replaced. Amplifier jumper settings are listed starting
on page 13A-16.
ATTENTION: Jumper settings configure the amplifier to
match the specific application. Failure to match jumper settings
on the new servo amplifier may result in damage to the
amplifier, servomotors, or machine.
11. Turn ON power to the control and servo amplifier.
