Cleaning function and
rotation monitor
The function will start in the manually selected position on the control
unit's DIP switch (refer to picture on page 18), but it is possible to change
this via Modbus. When the Modbus communication is activated the
manual settings give the settings for cleaning function and rotation
monitor a start value, but Modbus has priority.
High speed/Low speed High speed/Low speed are not controlled via Modbus.
Refer also to "High speed/Low speed" on page 7.
Manual speed
A1-A2 A1-A2 has priority over Modbus. Manual speed can be read and
activated via Modbus if A1-A2 are not connected. Refer also to
"Manual Speed" on page 8.
Max speed Max speed is set via the potentiometer. The DUC is configured so that
100 % of the reference value equates to the set rpm speed. Refer also to
"Max Speed" on page 8.
Resetting
Resetting can be made via Modbus, via the Reset button or via Remote
Reset. Refer also to "Resetting" on page 8 and "Remote Reset" on page 9.
Input signal This is controlled via Modbus.
Rotor speed The rotor speed can be read via Modbus.
Activation of Modbus communication and configuration of address, data transfer rate, parity and
termination are achieved through a 9-pole DIP switch. On delivery of the unit all DIP switches are set to
their OFF position. For setting and configuration of the DIP switches refer to the table on page 18.
Modbus communication is activated through DIP switches. A constant red LED starts to light straight
away if no message with the speed reference value has been received. This goes out once the message
with the speed reference value has been received. A green LED starts flashing if there is data traffic
present in the bus.
Settings made via Modbus are not saved in VariMax50M. When VariMax50M is restarted the setting
from the DUC has to be re-transmitted.
