Warning/Alarm
Description
Cause
Remedy
62 — Output frequency at
maximum limit
The output frequency has reached
the value set in [4–19] Max Output
Frequency.
Check the application to determine
the cause. Possibly increase the
output frequency. Be sure the system
can operate safely at a higher output
frequency. The warning will clear
wieh the output drops below the
maximum limit.
65 — Control card over
temperature
The cut-out temperature of the control
card is 80°C.
Check that the ambient operating
temperature is within limits.
Check for clogged filters.
Check fan operation.
Check the control card.
66 — Heatsink temperature
low
The frequency converter is too cold
to operate. This warning is based on
the temperature sensor in the IGBT
module.
Increase the ambient temperature of
the unit.
A trickle amount of current can be
supplied to the frequency controller
whenever the motor is stopped by
setting [2–00] DC Hold/Preheat
Current at 5% and [1–80] Function
at Stop.
67 — Option module
configuration has changed
One or more options have either been
added or removed since the last power
down.
Check that the configuration change
is intentional and reset the frequency
controller.
68 — Safe stop activated
Loss of the 24 VDC signal on terminal
37 has caused the frequency controller
to trip.
To resume normal operation, apply
24 VDC to terminal 37 and reset the
frequency controller.
69 — Power card
temperature
The temperature sensor on the power
card is either too hot or too cold.
Check that the ambient operating
temperature is within limits.
Check for clogged filters.
Check fan operation.
Check the power card.
70 — Illegal FC
configuration
The control card and power card are
incompatible.
Contact your supplier with the
typecode of the unit from the
80 — Drive initialized to
default value
Parameter settings are initialized to
default settings after a manual reset.
Reset the unit to clear the alarm.
92 — No flow
A no-flow condition has been detected
in the system.
[22–23] No-Flow Function is set
for alarm.
Troubleshoot the system and reset
the frequency converter after the fault
has been cleared.
93 — No Water/Loss of
Prime
A low power condition in the system
with the frequency converter operating
at high speed may indicate a the pump
is out of water or has lost prime.
[22–26] No Water/Loss of Prime
Function is set for alarm. The [22–
39] No Water/Loss of Prime Limit
is set too high.
Troubleshoot the system and reset
the frequency converter after the fault
has been cleared.
94 — Under Pressure
The system pressure is below the
Under Pressure limit (Under Pressure
Limit = Setpoint [22–25] Under
Pressure Difference).
This may indicate leakage in the
system. [22–50] Under Pressure
Function is set for alarm.
Troubleshoot the system, and reset
the frequency converter after the fault
has been cleared.
95 — Broken belt
Torque is below the torque level set for
no load, indicating a broken belt.
[22–60] Broken Belt Function is
set for alarm.
Troubleshoot the system and reset
the frequency converter after the fault
has been cleared.
