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 Control mode
Selecting the operation mode, following software enabling (1.131) and hardware enabling, the drive
controller runs as follows:
0 = frequency control mode, with the target value of the selected reference channel 1.130
1.130 Reference channel
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 (see 7.6.3.4 for Current Input)
1.100 Control mode
Selecting the operation mode, following software enabling (1.131) and hardware enabling, the drive
controller runs as follows:
