2.14 Preferred running direction
Address : D102
Write authorization : ebm-papst, customer, end customer
Coding:
This parameter specifies the preferred running direction
Value
Preferred running direction
0
Counter-clockwise
1
Clockwise
The MSB has no significance.
Permissible value range: 0..1
The new value becomes valid immediately (without reset) after writing this parameter.
If the fail-safe function is active and an interruption in the connection is detected, the direction of rotation is set
to the value " Rotating direction fail-safe mode " (holding register D15B). The parameter Preferred running
direction is then not relevant.
2.15 Store set value
Address : D103
Write authorization : ebm-papst, customer, end customer
This parameter specifies whether
the set value (holding register D001) is additionally stored in the Stored set value parameter
(holding register D00D)
The Enable RS485 parameter (holding register D00F) is also stored in Stored enable RS485 parameter
(holding register D16B) in the event of an interruption of the power supply
Coding:
Value
Function
0
Set value and Enable RS485 are not stored
The fan does not run after switching on the power supply or following reset
1
Set value and Enable RS485 are stored
The fan runs with the stored set value and Enable RS485 state after switching on the power
supply or following reset
The MSB has no significance.
Permissible value range: 0..1
