2.056 Fixed frequency 6
XX = Set the frequency, it could not be lower than minimum speed and higher than
maximum speed.
2.057 Fixed frequency 7
XX = Set the frequency, it could not be lower than minimum speed and higher than
maximum speed.
Minimum speed
This parameter cannot be changed, risk of damage on the machine!
7.6 Speed Control via Analogue Input
7.6.1 Description
In this operating mode, the speed is control by an analogue signal. This analogue signal
can be provided by the internal potentiometer or by one of the two analogue input of
the frequency drive.
Those analogues have the following characteristics:
Analogue inputs 1, 2
- In +/- 10 V or 0 … 20 mA
- In 2 … 10 V or 4 … 20 mA
- 10-bit resolution
- Tol/- 2 %
Voltage input:
- Rin = 10 kOhm
Current input:
- Working resistance = 500 Ohm
7.6.2 Speed Control via Internal Potentiometer
1.100 Operating mode
Selecting the operation mode, following software enabling (1.131) and hardware en-
abling, the drive controller runs as follows:
0 = frequency setting mode, with the target value of the selected target value source
1.130
1.130 Target value source
Determines the source from which the target value is to be read:
0 = internal potentiometer
7.6.3 Speed Control via Analogue Input 1
7.6.3.1 Voltage Input
1.100 Operating mode
Selecting the operation mode, following software enabling (1.131) and hardware en-
abling, the drive controller runs as follows:
0 = frequency setting mode, with the target value of the selected target value source
1.130
