SMARTDRIVE - VF1000M/VF1000L,TR
1 Overview
± 10 V reference input (FSIN2):
• Analog input with automatic direction of rotation selection
• Additional offset input for 1st analog input (FSIN)
• High-resolution analog input (16-bit)
Technical controller:
• PI controller for process control, e.g. pressure, temperature,
flow, winding drive, etc.
Note: All manufacturers’ declarations and acceptances issued
for the standard series are also applicable to theVF1000M,
TR and VF1000L, TR frequency inverters.
When the TR version is selected the following additional
versions are not possible:
VF1000M C2 and C8
VF1000L C1, C2, and OP1 ... OP10
VF1000L,HF
The variant described here is based on the standard
software:
V1.2 for VF1000M
V1.6 for VF1000L
Expanded functions in the standard software are not
automatically adopted into the software of theTR version.
The current injection (55_ISEL = 3,4,5) is not selectable.

3.1 Input FSIN2
The FSIN2 can be used as an additional reference input with the
following functions:
Parameter Setting Function
04-FSSEL 24 FSIN2 = ± 10 V reference input with automatic
direction of rotation selection
Hysteresis = ± 150 mV, STR input
as hardware enable
04-FSSEL 25 FSIN2 = 0 ... 10 V reference input
04-FSSEL 26 FSIN2 = offset to FSIN (see example)
+ 10 V at FSIN2 => add FMAX
2
- 10 V at FSIN2 => subtract FMAX
2
Example: FMAX = 50 Hz; FSIN = 5 V; FSIN2 = + 5 V
FOUT = 25 Hz (from FSIN) + 12.5 Hz (from FSIN2)
= 37.5 Hz

3.2 Technical Controller
The technical controller in theVF1000M andVF1000L controls process
variables such as pressure, temperature, flow rate, jump, etc. It is not
suitable for dynamic process variables such as rotational speed.

3.3 Commissioning the Controller
1) Connect the motor and control cables and set the motor
characteristic as set out in the Operation Manual.
2) Connect the actual and reference value signals to inputs FSIN
and FSIN2, observing the existing signal type.
Important: Only voltage signals can be fed in at input FSIN2.Current
signals and digital signals can only be fed in at FSIN.
3) Set parameter 04-FSSEL to the available reference signals.
4) Set the desired actual value signal with parameter 76-CONFI.
5) Optimize the resolution of the actual value signal with
parameters 93-LEVHI and 88-LEVLO.
6) As necessary, set the reference and actual value filters with
parameters 67-FST and 83-FST2 (see “Optimizing the
Controller”).
7) Set and optimize the control parameters 77-KP and 78-TN (see
“Optimizing the Controller”).
3.4 Optimizing the Controller
If current or voltage ripple occurs on the actual and reference signals,
it can be damped with the aid of low-pass filters.The time constants
of the filters can be set as follows:
Parameter Setting VAL Function
67_FST 0 ... 4 2 Referencefilter
83_FST2 0 ... 9 2 Actual value filter
Setting:
67-FST 01 2 3 4
