Signal ground for control interface
Analogue input 1 (set value); 0-10 V; Ri= 100 k
Fixed voltage output 10 VDC; +10 V ±3 %; max. 10 mA; short circuit proof; power supply for ext. devices (e.g. potentiometer)
Analogue input 1 (set value); 4-20 mA; Ri= 100
Digital input 1: enabling of electronics; enabling: open pin or applied voltage 5 to 50 VDC; disabling: bridge to GND or
applied voltage < 1 VDC; reset function: triggers software reset after a level change to < 1V
Digital input 2: parameter set switch 1/2; according to EEPROM setting, thr valid/used parameter set is selectable per BUS or per
digital input Din2. Parameter set 1: open oin or applied voltage 5 to 50 VDC; parameter set 2: bridge to GND or applied voltage < 1 VDC
Digital input 3: Control characteristic of the integrated controller; according to EEPROM setting, the control characteristic of the integrated
controller is normally/inversely selectable per BUS or per digital input; normal: open pin or applied voltage 5 to 50 VDC (control deviation =
actual sensor value - set value); inverse: bridge to GND or applied voltage < 1 VDC control deviation = set value - actual sensor value)
Analogue input 2; actual sensor value 0-10 V; Ri= 100 k
Fixed voltage output 20 VDC; +20 V +25/-10 %; max. 50 mA; short circuit proof; power supply for ext. devices (e.g. sensors)
Analogue input 2; actual sensor value 4-20 mA; Ri= 100
Analogue output 0-10 V; max. 5 mA; output of the actual motor control factor (output voltage of electronics)/of the actual motor speed;
function selectable per BUS; parametrisable curve
