The motor data settings for
● rated voltage in volts
● rated current in amperes
● shaft output in KW or hp
● rated frequency in Hz
● rated speed in RPM
from the rating plate must match the wiring (star/delta).
1. Press to change the parameter value.
2. Use keys and (or alter individual digits by pressing for 3 seconds) in
order to change the displayed value.
3. Press to confirm the setting.
⇨ The display changes automatically to the next commissioning step.
Specify the motor cooling method:
● 0: Self-ventilated - with fan on the motor shaft (factory setting)
● 1: Forced ventilation - with a separately driven fan
● 2: Liquid cooling
● 128: No fan
1. Press to change the parameter.
2. Use keys and in order to select the required control mode from the list.
V/f control with square characteristic (VF QUAD) is the normal choice for pump,
fan and compressor applications.
3. Press to confirm your selection.
⇨
The next step in the commissioning process is then displayed automatically.
Use macros to select predefined input and output circuits:
● 12: Enable via DI0, setpoint via AI0 (factory setting)
● 109: Enable and setpoint via Modbus
● 110: Enable and setpoint via BACnet
You can find further macros and applications in the "Installation / Commissioning"
guide.
Define the minimum and maximum frequencies at which the motor will operate
when it is enabled.
With respect to the minimum frequency selected, the analog input can be scaled
accordingly in this step, e.g. 20 % (0 V input signal then corresponds to 20 %, or
10 Hz).
Enter the ramp-up and ramp-down times in seconds. Press in order to select
the parameter and keys and to change the value.
Rating Recommended ramp time for fans
0.37 – 3 kW 30s
4 – 15 kW 60s
18.5 – 30 kW 90s
37 – 90 kW 120s
