How to calculate Input 1 compare and Input 1 cp error parameters:
Input 1 compare = (Compare value ) * 10000 / (Full range value)
Input 1 error = (Tolerance half window) 10000 / (Full range value)
Example 1:
Select analog input 1 to
Ramp ref 1
Speed base value
equal to 1500 [RPM]
10Volt or 20 mA on analog input 1 (Ramp ref 1=Speed base value).
The application requires a signaling at 700 [RPM] via a digital output, with a tolerance window equal to 100 [RPM]
Input 1 cp match
assigned to a programmable digital output.
Input 1 compare
= 700 * 10000 / 1500 = 4667
Input 1 cp error
= 100 * 10000 / 1500 = 666
Example 2:
Select analog input 1 to
Ramp ref 1
Speed base value
equal to 1500 [RPM]
10Volt or 20 mA on
Analog input 1
(
Ramp ref 1
=
Speed base value
).
The application requires a signaling at –700 [RPM] via LAN, with a tolerance window equal to ±100 [RPM]
Input 1 compare
= -700 * 10000 / 1500 = -4667
Input 1 cp error
= 100 * 10000 / 1500 = 666
Example 3:
Select analog input 1 to
Pad 0
10Volt or 20 mA on
Analog input 1
corresponds to Pad 0=2047.
The application requires a signaling at 700 [count] via a digital output, with a tolerance window equal to ±50 [count]
Input 1 cp match
assigned to a programmable digital output
Input 1 compare
= 700 * 10000 / 2047 = 3420
Input 1 cp error
= 50 * 10000 / 2047 = 244
Example 4:
Select analog input 1 to
PID feedback
10Volt or 20 mA on
Analog input 1
corresponds to
PID feedback
=10000.
The application requires a signaling at 4000 [count] via a digital output, with a tolerance band equal to ±1000 [count]
Input 1 cp match
assigned to a programmable digital output
Input 1 compare
= 4000 * 10000 / 10000 = 4000
Input 1 cp error
= 1000 * 10000 / 10000 = 1000
Example 5:
Select input 1 to
T current lim
10Volt or 20 mA on
Analog input 1
corresponds to
T current lim
= 100 [%]
The application requires a signaling at 50 [%] via a digital output, with a tolerance band equal to ±2 [%]
Input 1 cp match
assigned to a programmable digital output
Input 1 compare
= 50 * 10000 / 100 = 5000
Input 1 cp error
= 2 * 10000 / 100 = 200
