Drive Reset – CN9-3
When On, any fault conditions that are present will be reset and the drive
will begin the initial power-up sequence. If the fault condition still exists,
the drive will immediately return to the fault shutdown condition.
If a fault occurred while the motor was running, it is possible to reset and
then restart the drive while the motor is still coasting. The drive will regain
control of the motor and either stop it or return it to the commanded
operating speed, depending on the input signals applied.
Important: Approximately 2-3 seconds after a fault occurs, the fault
message is written to the fault history in EEPROM. If the Drive Reset is
turned On while the fault message is being written to EEPROM or while
parameter value changes are being written to EEPROM, the reset
command will be ignored. After the writing to EEPROM is complete, the
Drive Reset input must be replied to reset the drive. To avoid this, do not
apply the Drive Reset input until at least 5 seconds after a fault has
occurred.
Digital Ground – CN9-4, 8, 12, 17
These terminals serve as grounding points for the digital inputs.
Forward Run and Reverse Run – CN9-5, 6
Turning either the Forward or Reverse Run inputs On will cause the motor
to run at the speed commanded by the appropriate analog or digital speed
command input.
The relationship between the direction of rotation and the Forward Run and
Reverse Run digital commands and the analog velocity input command are
shown below. Direction of rotation is determined when viewing the motor
output shaft end.
