factory setting, the unit may report a fault
at Power on (undervoltage).
Sets the max. time allowed for auto restart
before a final trip, if selected in para. 309.
If "on" is selected the presence of a motor
is checked when there is 24 V voltage to
[0]
[1] terminal 27 and no start command has
been given (START, START REV. or
JOG). If a motor is not connected, the mes-
sage NO MOTOR is shown. This function
is not found for VLT
V, and VLT
If "on" is selected the motor will be pre-
heated by a DC current when motor
[0]
coasting is permitted (terminal 27 = on)
[1]
and no start command has been given
(START, START REV. or JOG). This func-
tion is not found for VLT
230 V, and VLT
The frequency converter calculates
whether the motor temperature exceeds
[0]
[1] the permissible limits. The calculation is
based on 1.16 x rated motor current (set
[2]
[3] in parameter 107). Four separate calcula-
tions are possible, so that one can be
[4]
chosen for each setup or the same
[5]
calculation can be used in several
[6]
setups. Select off if you do not want
[7]
either warning or trip.
[8]
Select warning only if you want a warning
in the display when the motor is overheating.
You can also program the frequency con-
verter to give a warning signal via the
signal outputs (parameters 407-410).
Select "trip" if trip is required when the motor
is overloaded.
You can also program the frequency con-
verter to give a alarm signal via the signal
outputs (parameters 407-410). See graph
on page 130.
The delay timers will influence the switch
