Parameter 07.025 Calibrate Analog Input 1 Full Scale
Short description Caibrates the input level for analog input 1
Mode Open‑Loop
Minimum 0
Default 0
Type 1 Bit Volatile
Display Format Standard
Coding RW, NC
For analog input 1, and in voltage mode only, the full scale value used to determine the input level can be changed from 10V by calibrating the input.
The calibration process is triggered by setting Calibrate Analog Input 1 Full Scale (07.025) to one. Calibrate Analog Input 1 Full Scale (07.025) is
cleared automatically when the calibration process is complete. After calibration the actions are as follows:
Input voltage
during Result
calibration
The calibration result is ignored and the full scale is set
V < 1.5V
to 10V. Analog Input 1 Full Scale (07.051) is set to zero.
The calibration result is ignored and the full scale or
1.5V < V < 2.5V
Analog Input 1 Full Scale (07.051) are not affected.
The calibration result is used to set full scale and the
V > 2.5V value is also stored in Analog Input 1 Full Scale
(07.051).
It should be noted that Analog Input 1 Full Scale (07.051) is a power-down save parameter, and so the result is automatically retained after power-
down.
Parameter 07.026 Analogue Input 1 Fast Update Active
Short description Analogue Input 1 Fast Update Active
Mode Open‑Loop
Minimum 0
Default
Type 1 Bit Volatile
Display Format Standard
Coding RO, ND, NC, PT
Analogue Input 1 Fast Update Active (07.026) is one if the destination for analogue input 1 is being updated at the fast rate of 250us.
Parameter 07.027 Analogue Input 2 Fast Update Active
Short description Analogue Input 2 Fast Update Active
Mode Open‑Loop
Minimum 0
Default
Type 1 Bit Volatile
Display Format Standard
Coding RO, ND, NC, PT
Analogue Input 2 Fast Update Active (07.027) is one if the destination for analogue input 1 is being updated at the fast rate of 250us.
Parameter 07.028 Analog Input 1 Current Loop Loss
Short description Displays when analog input 1 falls below 3mA
Mode Open‑Loop
Minimum 0
Default
Type 1 Bit Volatile
Display Format Standard
Coding RO, ND, NC, PT
If Analog Input 1 Mode (07.007) is set to any of the 4-20mA or 20-4mA modes and the current falls below 3mA then Analog Input 1 Current Loop Loss
(07.028) is set to one. If the current is more than 3mA or any other mode is selected then Analog Input 1 Current Loop Loss (07.028) is set to zero.
