Reference quantities, e. g.
Sampling time of the analog inputs: p0799[1] (4 ms)
Differential input! The maximum voltage difference between analog input terminals AI+, AI-, and the ground must not exceed 35 V.
For current measurement (p0756[0...1] = 2, 3), the voltage between differential inputs AI+ and AI- must not exceed
10 V or the impressed current must not exceed 80 mA, as otherwise the input will be damaged.
For p0756[0...1] = 0, 1, 4 the unit is V. For p0756[0...1] = 2, 3 the unit is mA.
Possible settings p0756[0...1]: 0: Unipolar voltage input (0 V ... +10 V) 1: Unipolar voltage input monitored (+2 V ... +10 V) 2: Unipolar current input (0 mA ... +20 mA) 3: Unipolar current input monitored (+4 mA to +20 mA) 4: Bipolar voltage input (-10 V ... +10 V)
Wire breakage sensing only activated when p0756 = 1, 3.
