● Multipoint V/f control,
● V/f control for applications in the textile industry,
● V/f control with FCC for applications in the textile industry,
● V/f control with independent voltage setpoint,
Vector control, output frequency between 0 Hz and 200 Hz:
● Speed control without encoder
● Torque control without encoder
Fixed frequencies 16, parameterizable
Skip frequencies 4, parameterizable
Setpoint resolution 0.01 Hz digital; 0.01 Hz serial; 10 bit analog
(motorized potentiometer 0.1 Hz [0.1% in PID mode])
Digital inputs
(dependent on the CU
type)
Up to 6 digital inputs, isolated; SIMATIC-compatible,
Low < 5 V, High > 10 V, maximum input voltage 30 V, switchable via terminals
- PNP Jumper terminal 69 with terminal 9
- NPN: Jumper 69 with terminal 28,
Notice! Either PNP or NPN must be jumpered in order that the inverter can function
Analog inputs
● 2 switchable (current/voltage), both configurable as additional digital inputs.
0 V to 10 V, 0 mA to 20 mA and -10 V to +10 V (AI0)
0 V to 10 V and 0 mA to 20 mA (AI1)
● 1 switchable (current / Ni1000) (AI2)
0/4 mA … 20 mA
NI1000: - 50°C … 150 °C
PT1000: - 50 °C … 250 C
● 1 fixed (NI1000, PT1000) (AI3)
NI1000: - 50°C … 150 °C
PT1000: - 50 °C … 250 C
Relay outputs 3, parameterizable

Analog outputs 2, parameterizable: 0 mA … 20 mA, 0 V … 10 V (AO0, AO1)
Dimensions (WxHxD) 73 mm x 199 mm x 65.5 mm
Weight 0.61 kg
Operating temperature - 10°C … +60 °C (possible restrictions as a result of the Power Module should be observed)
Storage temperature - 40°C … +70 °C
Humidity < 95 % RH, non-condensing
Note
As far as the environmental requirements are concerned, possible restrictions resulting from the permissible values for the
power module must be taken into account.
The control terminals on the Control Unit are galvanically isolated from the supply voltage (PELV).
