warning 40
, Overload of Digital Output Terminal
27
:
Check the load connected to terminal 27 or remove short-
circuit connection. Check Par. 5–00 Digital i/o Mode and Par.
5–01 Terminal 27 Mode.
warning 41
, Overload of Digital Output Terminal
29
:
Check the load connected to terminal 29 or remove short-
circuit connection. Check Par. 5–00 Digital i/o Mode and Par.
5–02 Terminal 29 Mode.
warning 42
, Overload of Digital Output On x
30/6
:
Check the load connected to x 30/6 or remove short-circuit
connection. Check Par. 5–32 Term X 30/6 Digi Out (mcb 101).
warning 42
, Overload of Digital Output On x
30/7
:
Check the load connected to x 30/7 or remove short-circuit
connection. Check Par. 5–33 Term x 30/7 Digi Out (mcb 101).
alarm 46
, Pwr. card supply:
The supply on the power card is out of range.
warning 47, 24 v
supply low:
The external 24 v dc backup power supply may be overload-
ed, otherwise contact your Armstrong supplier.
alarm 48, 1.8 v
supply low:
Contact your Armstrong supplier.
warning 49
, Speed limit:
The speed has been limited by range in Par. 4–11 Motor Speed
Low Limit [rpm] and Par. 4–13 Motor Speed High Limit [rpm].
alarm 50
, ama calibration failed:
Contact your Armstrong supplier.
alarm 51,
ama check Unom and Inom:
The setting of motor voltage, motor current, and motor
power is presumably wrong. Check the settings.
alarm 52
, ama low Inom:
The motor current is too low. Check the settings.
alarm 53
, ama motor too big:
The motor is too big for the ama to be carried out.
alarm 54
, ama motor too small:
The motor is too small for the ama to be carried out.
alarm 55
, ama par. out of range:
The Par. values found from the motor are outside
acceptable range.
alarm 56
, ama interrupted by user:
The ama has been interrupted by the user.
alarm 57
, ama timeout:
Try to start the ama again a number of times, until the ama is
carried out. Please note that repeated runs may heat the mo-
tor to a level where the resistance rs and rr are increased. In
most cases, however, this is not critical.
warning/alarm 58
, ama internal fault:
Contact your Armstrong supplier.
warning 59
, Current limit:
The current is higher than the value in Par. 4–18 Current Limit.
warning 60
, External Interlock:
External Interlock has been activated. To resume normal
operation, apply 24 v dc to t h e te rm in a l pr og r am me d f or
External Interlock and reset the inverter (via bus, Digital i/o
or by pressing Reset).
warning/alarm 61,
Tracking Error:
Tracking error. Contact your supplier.
warning 62
, Output Frequency at Maximum Limit:
The output frequency is limited by the value set in Par. 4–19
max Output Frequency
warning 64
, Voltage Limit:
The load and speed combination demands a motor voltage
higher than the actual dc link voltage.
warning/alarm/trip 65
,
Control Card Over Temperature:
Control card over temperature: The cut-out temperature of
the control card is 176°f (80°c).
warning 66
, Heatsink Temperature Low:
The heat sink temperature is measured as 32°f (0°c). This
could indicate that the temperature sensor is defective and
thus the fan speed is increased to the maximum in case the
power part or control card is very hot. If the temperature is
below 59°f (15°c) the warning will be present.
alarm 67
, Option Confi guration has Changed:
One or more options has either been added or removed since
the last power-down.
alarm 68
, Safe Stop:
Safe Stop has been activated. To resume normal operation,
apply 24 v dc to terminal 37 then send a Reset signal (via bus,
Digital i/o or by pressing Reset).
alarm 69,
Pwr. Card Temp:
Power card over temperature.
