 Verify that the all the parameters on the AC drive are set
correctly.
 Verify that the E-stop command to AC Drive has not
been activated (in other words, the button is not
pressed). By measuring 0V from MI1 to DCM. When the
E-stop message is present it will measure 24V (button is
pressed).
 Verify the parameters on the AC Drive are correct.
5.6.2 Spindle AC Drive
The spindle AC Drive is a 3HP 3phase 220 VAC input drive or if the user orders the 400 volt
option, it will be 440 VAC input. The AC drive is able to drive the spindle motor up to 6000 RPM,
which is 200 HZ on the AC Drive. The AC drive contains an encoder input PCB in order to
perform the spindle orientation. Without the encoder input to the drive the AC drive will fault out.
Once the AC drive receives the encoder input it then sends it out to the computer module. When
the E-stop is pressed, the AC drive will automatically decelerate to a stop.
The spindle braking is done via a braking resistor that is found on the top of the machine. The
resistor is rated at 500 watts and has 100 ohms of resistance for 220 volt power and 200 ohms
for 440 volt power. If the spindle is not braking properly, check the resistance of the resistor
with an ohmmeter.
All the digital inputs to the drive are 24 volts DC. There are 5 digital inputs to the AC drive and 2
outputs commands to the computer module.
The AC Drive operator, seen in Figure 5.6.2C may be used to display the frequency input,
frequency output, output current, and the digital inputs. As a default whenever the AC Drive is
initially turned on, it will be in the Frequency input mode. Every time the Mode button is press
the AC drive will scroll through the following modes and in the following sequence.
1. Frequency Input Mode – In this mode the AC drive will display the frequency command
from the computer module. Note the letter “F” on the top left of the operator will turn
red when in this mode.
2. Frequency Output Mode – In this mode the AC drive will display the frequency command
output t o the motor. Note the letter “H” on the top left of the operator will turn red when
in this mode.
3. Digital Input Mode (User Define) – In this mode the AC drive will display whatever digital
input is triggered in Hexadecimal from the computer module. Note th e letter “U” on the
top left of the operator will turn red when in this mode. The following are the digital
inputs codes.
a. 0000 – Means that no digital input is activated.
b. 0001 – Means that the FWD command input has been activated
c. 0002 – Means that the REV command has been activated.
d. 0004 – Means that the E-stop command has been activated.
e. 0008 – Means that Reset command has been activated
f. 0010 – Means that the Orientate command has been activated.
g. 0011 – Means that the Orientate and FWD command input has been activated.
This is necessary when performing a tool change.
h. 0020 – means that the tap mode command has been activated.
4. Current Output Mode – In this mode the AC Drive will display the current being used by
the motor. Note an “ A ” will be displayed in front of the current value. The following
RPM’s should produce the noted current under a no load condition.
a. 100 RPM – 6 amps
b. 1000 RPM – 6 amps
c. 1800 RPM – 5.4 amps
