LO - Output Parameters
The outputs are available to be programmed with one of the following output
functions listed in table below.
Setting: Description: NUM
Off Output is disabled.
0
Fault* Output is set when there is a drive fault.
1
Drive Ready* Output is set when there are no drive faults and the
drive is ready for operation. 2
Drive On Output indicates the drive is outputting current and
in control of the motor.
The output is set when the motor phase current
check (LX08; initiated by the drive enable and
a direction input) has passed and the motor is
magnetized, the LT01 Brake Release Delay has
expired, and output voltage modulation has begun.
The output turns off after the speed command has
ramped down to zero, the direction input has been
turned off, and the sum of the LT10 Brake Drop
Delay and LT12 Current Hold Time have elapsed
or immediately if the drive enable is dropped at any
time or a drive fault occurs.
If the drive enable has not been dropped or a drive
fault does not occur, then after the LT12 Current
Hold Time has elapsed and the Drive On output
has turned off the drive will continue to ramp down
the output current during the LT13 Current Ramp
Down Time. During this ramp down time the drive
is not in full control of the motor so the Drive On
output will not be on even though current may still
be output. Therefore, the brake should be set within
the LT12 Current Hold Time before the LT13 Current
Ramp Down time and the Drive On should not be
used to control the brake. In addition, the drive
enable input should remain on for at least the LT13
Current Ramp Down time after the Drive On output
has turned off to prevent immediately shutting off
the output current during the ramp down period
which may cause a motor disturbance.

*NOTE: Fault (1) and Drive Ready (2) cannot be used together!
