811 Access Code
Default: 0
Range: 0-9999
Level 2
The security
Access Code
allows the user to control access to the programmable functions of the inverter. The initial
value of this parameter is 0, which signifies that no access code is necessary. Any number between 1 and 9999 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 actual 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 parameter. If you enter an incorrect access code, the drive displays **WRONG CODE** and allows
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 0.
812 Freq Ref Output
Default: 6FS
Range: n/a
Level 2
The
Frequency Reference Output
parameter determines the frequency pulse-train output from the DOP terminal. This
digital output is a pulse train that can be linked to another 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
813 Speed Ratio
Default: 100.0%
Range: 0.0%-200.0%
Level 2
The
Master / Follower Speed Ratio
parameter allows the pulse train output of one X5 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 function in parameter
204
.
814 Display Status
Default: Drive Load
Range: 0.0%-200.0%
Level 2
This parameter allows configuration of the additional parameter status field on the operate screen. The following fields
can be configured:

816 Fly Catch Mode
Default: Sweep Fwd
Range: n/a
Level 2
This parameter configures how the “catch on the fly” operates.
Parameter Value
Description
Sweep Fwd
Catch on the fly algorithm sweeps through frequencies only in the forward direction while
searching for the operating frequency
Sweep Rev
Catch on the fly algorithm sweeps through frequencies only in the reverse direction while
searching for the operating frequency
Sweep F/R
Catch on the fly algorithm sweeps through frequencies in both directions while searching for the
operating frequency. The direction that is chosen first depends on the direction of the command
given to the drive. Note that this option is slower than the other two modes of operation.
819 Flt Text #1
Default: User Flt 1
Range: n/a
Level 2
This parameter defines text to be displayed for fault message #1. All ASCII options are permitted.
