YASKAWA TM.iQp.02 iQpump Drive Programming Manual
Description
Digital Outputs
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.
40: Pump 2 Control
Open: Shutdown Additional Pump 2.
Closed: Start Additional Pump 2.
Function Active in multiplex mode.
Contactor control for second pump.
41: Pump 3 Control
Open: Shutdown Additional Pump 3.
Closed: Start Additional Pump 3.
Function Active in multiplex mode.
Contactor control for second pump.
