Frequency reference
source
Ref Source
Open: External Reference 1 or 2 supplies the frequency reference (set in b1-01 or
b1-15).
Closed: Digital operator supplies the frequency reference.
–
A HAND mode Hand Mode
Open: External Reference 1 or 2 supplies the Run command (set in b1-02 or b1-16).
Closed: Pump is in HAND Mode operation.

Torque detection 1
(N.O.)
Trq Det 1 N.O.
Closed: An overtorque or undertorque situation has been detected.

C
Frequency reference
loss
Loss of Ref
Closed: Analog frequency reference has been lost.
Frequency reference loss is detected when the frequency reference drops below
10% of the reference within 400 ms.
–
D Braking resistor fault DB Overheat Closed: Braking resistor or transistor is overheated or faulted out. –
E Fault Fault Closed: Fault occurred. 144
F Through mode Not Used Set this value when using the terminal in the pass-through mode. –
10 Minor fault Minor Fault
Closed: An alarm has been triggered, or the IGBTs have reached 90% of their
expected life span.
–

BaseBlk 2
Open: Drive has entered the baseblock state (no output voltage).
–
1E Restart enabled Dur Flt Restart Closed: Automatic restart is performed –
1F
Motor overload alarm
(oL1)
Overload (OL1)
Closed: oL1 is at 90% of its trip point or greater. An oH3 situation also triggers
this alarm.
–
20
Drive overheat pre-
alarm (oH)
OH Prealarm
Closed: Heatsink temperature exceeds the parameter L8-02 value.
–
22
Mechanical weakening
detection
MechFatigue(OL5)
Closed: Mechanical weakening detected.

During frequency
output
During RUN 2
Open: Either the drive has stopped or baseblock, DC Injection Braking, or Initial
Excitation is being performed.
Closed: Drive is running the motor (not in a baseblock state and DC Injection is
not being performed).
