Programming
Function:
In this parameter it is possible to see the reason for a trip
(cut-out of the frequency converter) occurring. 10 [1-10]
log values are defined.
The lowest log number [1] contains the latest/most
recently saved data value. The highest log number [10]
contains the oldest data value saved. If a trip occurs, it is
possible to see the cause, time and a possible value of the
4 4
output current or output voltage.
Description of choice:
Given as a fault code, in which the number refers to a
table. See chapter 5.2.2 Warnings and Alarm Messages
616 Fault log: Time
Value:
[Index 1 - 10] Hours: 0 - 130,000.0
Function:
In this parameter it is possible to see the total number of
operating hours in connection with the last 10 trips.
10 [1-10] log values are denoted. The lowest log number
[1] contains the latest/most recently saved data value, and
the highest log number [10] contains the oldest data
value.
Description of choice:
Read out as one value.
617 Fault log: Value
Value:
[Index 1 - 10] Value: 0 - 9999
Function:
In this parameter it is possible to see at which value a trip
occurred. The unit of the value depends on which alarm is
active in parameter 615 Fault log: Fault code.
Description of choice:
Read out as one value.
618 Reset of kWh counter
Value:
No reset (DO NOT RESET)
Reset (RESET COUNTER)
Function:
Resetting parameter 602 kWh counter to zero.
Description of choice:
If [1] Reset is selected, press the [OK] key to reset the
frequency converter's kWh counter to 0. This parameter
cannot be selected via serial communication.
NOTICE
When the [OK] key is activated, the counter is reset to
zero.
619 RESET RUNNING HOURS COUNTER
Value:
No reset (DO NOT RESET)
Reset (RESET COUNTER)
124
Design Guide
Function:
Resetting of parameter 601 Hours run to zero.
Description of choice:
If [1] Reset is selected, press the [OK] key to reset the
frequency converter's parameter 601 Hours run to 0 Hours
run. This parameter cannot be selected via serial communi-
cation.
NOTICE
When the [OK] key is pressed the parameter is reset to
zero.
620
Value:
Function:
In addition to its normal function, this parameter can be
used to test the control card.
There is also the opportunity to perform an initialisation at
the factory setting for all parameters in all set-ups, with
the exception of parameters 500 Address, 501 Baudrate,
600-605 Operating data and 615-617 Fault log.
Description of choice:
[0] Normal function is used for normal operation of the
motor.
Select [2] Control card test to check the control card's
analog/digital inputs, analog/digital outputs, relay outputs
and 10 V and 24 V voltages.
The test is performed as follows:
27-29-33-46 are connected.
50-53 are connected.
42-60 are connected.
12-relay terminal 01 is connected.
18-relay terminal 02 is connected.
19-relay terminal 03 is connected.
