This parameter configures the language text strings will be displayed in. The following
data values may be assigned:
Parameter Value
English
Spanish
German
Italian
French
The security Access Code allows the user to control access to the programmable func-
tions of the inverter. The initial value of this parameter is 000, which signifies that no ac-
cess code is necessary. Any number between 001 and 999 may be used for an access
code, but is not necessary. If an access code is entered, you will not be able to view the
values while scrolling through parameters. Only after the Shift key is pressed will the ac-
tual value appear.
To enter an access code, re-program parameter 811 as you would any other parameter.
After the new value is stored, you have 10 minutes of free access. If you remove power
and then restore it, you will need to enter the access code to change any program param-
eter. If you enter an incorrect access code, the drive displays **WRONG CODE** and al-
lows only viewing rights to the various parameters. Once the correct code is entered, you
again have 10 minutes of free access unless power is removed and restored. To disable
the access code requirement, set parameter 811 back to 000.
The Frequency Reference Output parameter determines the frequency pulse-train out-
put from the DOP terminal. This digital output is a pulse train that can be linked to anoth-
er drive or to a field meter for speed indication. The pulse train is a 50% duty cycle signal
and requires a pull-up resistor of approximately 4.7 kOhms.
The following data values may be assigned to this parameter:
Parameter Value
6FS
48FS
The Master / Follower Speed Ratio parameter allows the pulse train output of one Vacon
50X series drive (master) to be used to control the speed of up to 8 other follower drives.
The output of each follower can be individually programmed, or trimmed “ON-THE-FLY”
with A2-RATIO. The range of adjustment is 0–200% of the master. This function only
works when using the 6FS or 48FS functions in parameter 204.
This parameter allows configuration of the additional parameter status field on the oper-
ate screen. The following fields can be configured:
810 Language Default: English
Range: Text string
Level 2, Macro
811 Access Code Default: 0
Range: 0–9999
Level 2
812 Freq Ref Output Default: 6FS
Range: Text string
Level 2
813 Speed Ratio Default: 100.0%
Range: 0.0–200.0%
Level 2
814 Display Status Default: Drive Load
Range: Text string
Level 2
