14.5.2 Error Code
Errors of the DRn function are displayed in the parameters D0.88 and D0.89
according to the following tables. When an error occurs, the display shows
"APF1" in every case. The value in the "Code" column can be examined from
D0.88 and D0.89 to find out which error occurred.
An error prevent DRn from starting and driving the motor. As long as an error
is in queue DRn will put out zero speed as a set-point value.
Bit Code Condition Reason Solution
6 64 F3.21 > F4.50
Speed adaptation ramp pitch (as‐
cending) exceeds maximum pump
angular acceleration
Set F3.21 to smaller values
7 128 |F3.22| > F4.50
Speed adaptation ramp pitch (de‐
scending) exceeds maximum pump
angular acceleration
Set the absolute value of F3.22 to
smaller values
8 256 F3.23 > F4.50
Speed boost ramp pitch exceeds
maximum pump angular accelera‐
tion
Set F3.23 to smaller values
11 2048 F3.19 < F4.52
Speed adaptation minimum speed
is lower than minimum pump speed Set F3.19 to higher values
12 4096 F3.20 > F4.51
Speed adaptation maximum speed
exceeds maximum pump speed
Set F3.20 to smaller values
13 8192 F3.19 > F3.20
Speed adaptation minimum speed
is higher than speed adaptation
maximum speed
Set F3.20 and F3.19 so that F3.20
is bigger than F3.19

Bit Code Condition Reason Solution
1 2 Parameter setting fault Parameter setting repetition
Check if parameter settings are in
conflict
5 32 F4.55 > 100
Motor derating-continuous torque at
standstill exceeds motor nominal
torque
Continuous torque at standstill
must be set to values smaller then
100% of nominal torque. Set F4.55
to <100
11 2048 Pump type invalid
Chosen pump type is not available
or manual configuration of pump
data is invalid (F4.30,
F4.50...F4.54)
Chose pump type to an available
pump
12 4096 Oil level error Oil level too low
Refill oil. See chapter "Digital Input"
on page 100 for more information
13 8192 Oil temperature error Oil temperature reached
Reduce hydraulic loses or enhance
oil cooling. See chapter "Digital In‐
put" on page 100 for more informa‐
