Specifications

XYZ Motor Drive Amplifiers
There are three identical XYZ Motor Drive Amplifiers located inside the motor
amplifier assembly in the top support platform between heads #3 and #4 (see
Figure 2-13). Refer to the following procedure for replacement.
WARNING! When the cover is removed, and the machine is ON,
potential harmful voltage and current is exposed.
The capacitors in this section store high voltage for a few moments after
power is removed, therefore extreme care is advised when working in this
area immediately after removing power.
It is advised that you delay any work in this area for at least one (1) minute
after removing power, to allow the voltage to "bleed" from the capacitors.
Current Limit Switch Settings
Before installing any new Motor Drive Amplifier, you must set the current limit DIP
switches on the module. The current limit switch setting for the amplifier associated
with the either the X or Y axis is the same, but is different for the Z axis. Refer to
the following steps and set the switches accordingly.
1. Refer to Figure 2-16 and locate the current limit DIP switches on the motor drive
amplifiers as indicated.
2. Using a small
screw driver or
similar device,
position the DIP
switch settings
to the proper
positions as
shown in the
enlarged
sections of
Figure 2-16.
For X and Y
modules:
#1 ON, #2 OFF,
#3 OFF, #4 ON.
For the Z
module:
#1 ON, #2 ON,
#3 OFF, #4 ON.
