6. DAC (digital to analog) signal is an analog 0 to 10 Volt signal that is used to control the
speed of the spindle motor. This is the AVI terminal on the AC Drive. When measuring
AVI voltage use ACM terminal for reference.
Outputs
1. Fault (RB and RC terminals) output, is used to indicate a fault has occurred on the AC
drive to the computer module. When a fault occurs the voltage between terminals RB
and RC will be 5 volts DC and when it is okay it will be 0 volts.
2. 100% Torque Achieved (MRA and MRC terminals) output, is used to indicate when the
actual spindle is equal to the 100% of the full torque of the motor. When the spindle
torque output is 100% the voltage between the MRA and MRC terminals will be 0 volts
and when it is not it will be 5 volts. ***This feature was not implemented upon
product release.
Symptoms Diagnostics
Spindle will not perform a spindle
orientate command.
 Verify that the orientation command is being sent
to the AC drive by measuring 0 VDC from MI3 to
DCM terminals and from the FWD to DCM
terminals of the AC drive when the orientation
command is triggered.
 Verify that the all the parameters are set
correctly on the AC Drive.
 Verify that the E-stop command to AC Drive has
not been activated. By measuring 0V from MI1 to
DCM. When the E-stop command is present it will
measure 24V.
The AC Drive will fault out
immediately when starting the
spindle.
 Verify that the spindle AC drive encoder PCB is
properly seated.
 Verify the spindle encoder on the motor works.
 Verify that the wiring on the AC drive is correct.
 Verify that the parameters on the AC drive are
correct.
The AC drive has a Fault and it is
unable to clear the fault.  Verify that the spindle Reset signal is being sent to
the AC drive by measuring the voltage between
MI3 and DCM on the AC drive. When the reset
command is given, it should be 0 VDC and 24 VDC
when no reset command is given.
