An alarm occurs when the value set at Pr.86 is
above the value set at Pr.87. To receive fan
exchange output signals, set the digital output
terminal or relay OU.31 or OU.33 to 38 ‘FAN
EXCHANGE’.
An alarm occurs when the value set at Pr.63 is less
than the value set at Pr.62 (the value set at Pr.61
must be 2 ‘Pre Diag’). To receive CAP exchange
signals, set the digital output terminal or relay
OU.31 or OU.33 to 36 ‘CAP Exchange’.
Displayed when the DB resistor usage rate
exceeds the set value. Set the detection level at
Pr.66
Tr tune error warning alarm is activated when dr.9
is set to 4 ‘S-less1’. The warning alarm occurs
when the motors rotor time constant (Tr) is either
too low or too high.
