Term M1-M2 Sel
0: During RUN 1 = Closed when a run command is input
or the Drive is outputting voltage.
1: Zero Speed = Closed when Drive output frequency is
less
than Fmin (E1-09)
2: Fref/Fout Agree 1 = Closed when Drive output speed
equals the speed command within the bandwidth of
L4-02.
3: Fref/Set Agree 1 = Closed when the Drive output speed
and the speed command are equal to the value in L4-01
within the bandwidth of L4-02.
4: Freq Detect 1 = Closed when the Drive output speed is
less than or equal to the value in L4-01, with hysteresis
determined by L4-02.
5: Freq Detect 2 = Closed when the Drive output speed
is greater than or equal to the value in L4-01, with
hysteresis determined by L4-02.
6: Inverter Ready = Closed when the Drive is not in a fault
state, and not in program mode.
7: DC Bus Undervolt = Closed when the DC bus voltage
falls below the UV trip level (L2-05)
8: Base Blk 1 = Closed when the Drive is not outputting
voltage.
9: Operator Reference = Closed when the speed command
is coming from the digital operator.
A: Remote/Auto Oper = Closed when the run command is
coming from the digital operator.
B: Trq Det 1 N.O. - Closes when the output current exceeds
the value set in parameter L6-02 for more time than is set
in parameter L6-03.
C: Loss of Ref - Closes when the Drive has detected a loss
of analog speed command.
Speed command is considered lost when it drops 90% in
0.4 seconds.
Parameter L4-05 determines Drive reaction to a loss of
speed command.
D: DB Overheat
E: Fault - Closes when the Drive experiences a major fault.
F: Not Used
10: Minor Fault - Closes when Drive experiences a minor
fault or alarm.
11: Reset Cmd Active - Closes when the Drive receives a
reset command from terminals or serial comms.
12: Timer Output - Output for independent timer, controlled
by b4-01 and b4-02.
Used in conjunction with a multi-function digital input.
17: Trq. Det 1 N.C. - Opens when the output current
exceeds the value set in parameter
L6-02 for more time than is set in parameter L6-03.
1A: Reverse Dir - Closes when the Drive is running in the
reverse direction.
1E: Restart Enabled - Closes when the Drive is performing
an automatic restart.
Automatic restart is configured by parameter L5-01.
1F: Overload (OL1) - Closes before a motor overload
occurs. (90% of OL1 time)
20: OH Prealarm - Closes when the Drive’s heatsink
temperature exceeds the setting
of parameter L8-02.
38: Drive Enable - Closes when the Drive enable input is
active.
39: Waiting to Run - Closes during the time after a run
command is issued, but the Drive is not running due to
the time set in parameter b1-10.
3A: OH Freq Reduce
3B: Run Src Com/Opt
3D: Cooling Fan Err = Closed during internal cooling fan
failure
