2.35 Rotating direction fail-safe mode
Address : D15B
Write authorization : ebm-papst, customer
If the fail safe function is active and a break in the Set value source (holding register D101) is detected, the
direction of rotation is set to the value defined here. Then the setting for the parameter "Preferred running
direction" (holding register D102) is not relevant.
Coding:
Value
Rotating direction fail-safe mode
0
Counter-clockwise
1
Clockwise
2
None (set direction of rotation is retained)
The MSB has no significance.
Permissible value range: 0..2
