Warning Functions - Trane TR1 6002 Installation And Operation Manual

Warning Functions

The warning functions in parameters 221 through 228 are not active
during ramp-up after a Start command, ramp down after a Stop
command, or while stopped. The warning functions are activated when
the output frequency has reached the resulting reference.
The signal outputs can be programmed to generate a warning signal
via terminal 42 or 45 and via the relay outputs.
The reference limits in parameter 226, Warning: High Reference and
parameter 227, Warning: Low Reference are only active when remote
reference has been selected.
221 Warning: Low Current
Value:
0.0 to parameter 222 Warning: High current
Function:
When the motor current is below the limit programmed in this parameter,
the display shows a flashing CURRENT LOW, provided Warning has
been selected in parameter 409, Function in Case of No Load. The
drive will trip if parameter 409 has been selected as Trip. This can be
used to indicate when a belt between the motor and the driven load is
broken.
Description of choice:
The lower signal limit must be programmed within the normal working
range of the drive.

222 Warning: High Current
Value:
Parameter 221 to 1.1 x rated current
Function:
If the motor current is above the limit programmed in this parameter, the
display shows a flashing CURRENT HIGH.
Description of choice:
The upper signal limit of the motor frequency must be programmed
within the normal working range of the drive. See the drawing at
parameter 221, Warning: Low Current.
223 Warning: Low Frequency
(WARN. LOW FREQ)
Value:
0.0 to parameter 224
Function:
If the output frequency is below the limit programmed in this parameter,
the display will show a flashing F OUT < FLOW.
Description of choice:
The lower signal limit of the motor frequency must be programmed
within the normal working range of the drive. See drawing at parameter
221 Warning: Low current.
224 Warning: High Frequency
(WARN. HIGH FREQ.)
Value:
Par. 200 Output frequency range = 0 to 120 Hz
parameter 223 - 120 Hz
Par. 200 Output frequency range = 0 to 1000 Hz
parameter 223 - 1000 Hz
Function:
If the output frequency is above the limit programmed in this parameter,
the display will show a flashing F OUT > F HIGH
Description of choice:
The higher signal limit of the motor frequency must be programmed
within the normal working range of the drive. See the drawing at
parameter 221, Warning: Low Current.
