Factory Setting
When this parameter is set to 0 (disabled), the 0-10V DC and 4-20mA
analog inputs at terminal block TB2 in the drive will function as described
in the User Manual.
When set to 1 (enabled), the 0-10V DC and 4-20mA analog inputs at TB2
will still function as described in the User Manual, but will produce an
inverse signal. A 0V DC or 4mA signal will produce maximum drive
output frequency as set by Parameter 19. A 10V DC or 20mA signal will
produce minimum drive output frequency as set by Parameter 16.
!
ATTENTION: Unexpected machine acceleration can cause injury
or death.
If Parameter 84 is enabled, a loss of the 4-20mA or 0-10V DC
reference signal at drive terminal block TB2 will allow the drive to
immediately accelerate to the maximum frequency set by
Parameter 19.
Ensure that all control connection integrity is maintained and
routinely inspected.
