Input/output Terminal X3 Informaon
Digital inputs DI1, DI2, DI3, DI4, DI5 DI3/DI4 can be oponally used as frequency or encoder input.
HIGH-acve/LOW-acve switchable LOW = 0 ... +3 V,
HIGH = +12 V ... +30 V
Digital outputs DO1 Digital output (max. 100 mA for DO1 and 24-V output)
Analog inputs AI1, AI2 Can be oponally used as voltage input or current input.
Analog outputs AO1 Can be oponally used as voltage output or current output.
24-V input 24E Input for mains-independent power DC supply of control electronics
(including communicaon). Max. 1 A
10-V output 10 V Primarily for the supply of a potenometer (1 ... 10 kΩ).
Max. 10 mA
24-V output 24 V Primarily for the supply of digital inputs. (Max. 100 mA for DO1
and 24-V output)

5.5 PTC input
In the default seng, the motor temperature monitoring is acve! By default, a wire jumper
is installed between the terminals T1 and T2.
Before connecng a thermal sensor, remove the wire jumper.
