Function description
OUTPUTS → PULSE/FREQUENCY OUTPUT 1 → OPERATION (FREQUENCY)
ACTUAL
FREQUENCY
MODBUS register:
Data type:
Access:
4301
3218
Float
read
! Note!
Function is not available unless the FREQUENCY setting was selected in the
OPERATION MODE function (4200).
Use this function to view the computed actual value of the output frequency.
Display: 0 to 12500 Hz
SIMULATION
FREQUENCY
MODBUS register:
Data type:
Access:
4302
3220
Integer
read/write
! Note!
Function is not available unless the FREQUENCY setting was selected in the
OPERATION MODE function (4200).
Use this function to activate simulation of the frequency output.
Options:
0 = OFF
1 = ON
Factory setting: OFF
! Note!
• The “SIMULATION FREQUENCY OUTPUT” message indicates that
simulation is active.
• The measuring device continues to measure while simulation is in progress, i.e.
the current measured values are output correctly via the other outputs.
" Caution!
The setting is not saved in the event of a power failure.

FREQUENCY
MODBUS register:
Data type:
Access:
4303
3221
Float
read/write
! Note!
Function is not available unless FREQUENCY was selected in the OPERATION
MODE function (4200) and the SIMULATION FREQUENCY function (4302) is
active (= ON).
Use this function to define a free selectable frequency value (e.g. 500 Hz) which
should be output at the frequency output (with maximum pulse frequency or
shortened minimum pulse width). This value is used to test downstream devices
and the measuring device itself.
User input: 0 to 12500 Hz
Factory setting: 0 Hz
" Caution!
The setting is not saved in the event of a power failure.
