Remote
reference
active
Output is high when 3-13 Reference Site
=[1] Remote or [0] Linked to hand/auto
while the LCP is in [Auto on] mode. See
Table 6.8.
[122] No alarm Output is high when no alarm is present.
[123] Start
command
active
Output is high when there is an active
start command (via digital input bus
connection or [Hand on] or [Auto on]), and
no stop or start command is active.
[124] Running
reverse
Output is high when the adjustable
frequency drive is running counter
clockwise (the logical product of the status
bits ‘running’ and ‘reverse’).
[125] Drive in hand
mode
Output is high when the adjustable
frequency drive is in hand on mode (as
indicated by the LED light above [Hand
on]).
[126] Drive in auto
mode
Output is high when the adjustable
frequency drive is in [Hand on] mode (as
indicated by the LED light above [Auto
on]).
[151] ATEX ETR cur.
alarm
Selectable if parameter 1-90 Motor Thermal
Protection is set to [20] Above feedback
high or [21] Thermal warning. If the alarm
164 ATEX ETR cur.lim.alarm is active, the
output is 1.
[152] ATEX ETR freq.
alarm
Selectable if parameter 1-90 Motor Thermal
Protection is set to [20] Above feedback
high or [21] Thermal warning. If the alarm
166 ATEX ETR freq.lim.alarm is active, the
output is 1.
[153] ATEX ETR cur.
warning
Selectable ifparameter 1-90 Motor Thermal
Protection is set to [20] Above feedback
high or [21] Thermal warning. If the alarm
163 ATEX ETR cur.lim.warning is active, the
output is 1.
[154] ATEX ETR freq.
warning
Selectable if parameter 1-90 Motor Thermal
Protection is set to [20] Above feedback
high or [21] Thermal warning. If the
warning 165 ATEX ETR freq.lim.warning is
active, the output is 1.
[188] AHF Capacitor
Connect
The capacitors are turned on at 20%
(hysteresis of 50% gives an interval of
10%–30%). The capacitors are discon-
nected below 10%. The off delay is 10 s
and restart if the nominal power goes
above 10% during the delay. 5-80 AHF Cap
Reconnect Delay is used to guarantee a
minimum off-time for the capacitors.
[189] External fan
control
The internal logic for the internal fan
control is transferred to this output to
make it possible to control an external fan
(relevant for HP duct cooling).
