Troubleshooting: Drive Motor Control Box Description

User Inputs/Outputs
User inputs and outputs are available at the 15-pin, D-connector
located at the top of the drive. See figure for a list of the functions and
pin numbers. Signal functions are as follows:
HALL1, HALL2, HALL3
These signals originate from the commutation hall sensors in the DC
motor and are used to decode the rotor position so that the correct
phase is energized. They are 5-volt, square waves, displaced 90 electrical
degrees apart. You can check the signals with a voltmeter while slowly
rotating the motor by hand and verifying the +5 volt and near-zero volt
levels.
HALL4, HALL5
These signals originate from the auxiliary hall sensors in the DC motor,
and they supply a tachometer signal to the drive for speed regulation.
These are 5-volt, square waves, displaced approximately 90 degrees
from each other. You can check the signals with a voltmeter while slowly
rotating the motor by hand and verifying the +5 volt and near-zero volt
levels.
+5ISOL
This signal is the power for the motor hall sensor.
GNDISOL
This is the common for all of the user I/O.
VIN
This is a 0–10.3 volt signal that controls the speed of the drive.
START
This is a normally-open switch input. Connecting this input to
GNDISOL starts the drive unless there is a fault condition or the STOP or
ESTOP contacts are open. The signal is pulled down to –15V ISOL.
STOP
This is a normally-closed switch input. Opening this switch signals the
drive to power to a stop with full braking. The drive brakes until it
reaches zero speed unless a fault occurs or the ESTOP switch is open.
The signal is pulled down to –15V ISOL.
ESTOP
This is a normally-closed switch input. Opening this switch signals the
drive to coast to a stop. This also clears any faults that have been latched
unless the fault condition still exists. The signal is pulled down to –15V
ISOL.
