VLT Automation Low Harmonic Drive Operating Instructions
Selectable if 1-90 Motor Thermal Protection
is set to [20] or [21]. If the warning 165
ATEX ETR freq.lim.warning is active, the
output will be 1.
The capacitors will be turned on at 20%
(hysteresis of 50% gives an interval of
10% - 30%). The capacitors will be discon-
nected below 10%. The off delay is 10s
and will restart if the nominal power goes
above 10% during the delay. 5-80 AHF
Cap Reconnect Delay is used to guarantee
a minimum off-time for the capacitors.
The internal logics for the internal fan
control is transferred to this output to
make it possible to control an external
fan (relevant for HP duct cooling).
Function:
All digital and relay outputs are
default set to "No Operation".
The control card is ready. E.g.:
Feedback from a drive where the
control is supplied by an external 24
V (MCB 107) and the main power to
drive is not detected.
Drive is ready to operate. Mains and
control supplies are OK.
The frequency converter is ready for
operation and is in Auto On mode
commands have been applied (start/
disable). No warnings are active.
Motor is running, and shaft torque
present.
Output speed is higher than the
speed set in 1-81 Min Speed for
Function at Stop [RPM] Min Speed for
Function at Stop [RPM]. The motor is
running and no warnings.
Motor is running within the
programmed current and speed
ranges set in 4-50 Warning Current
Low and 4-53 Warning Speed High.
No warnings.
Motor runs at reference speed. No
warnings.
An alarm activates the output. No
