P-52
Motor Parameter Autotune
0
1
0
-
This parameter can be used to optimise the performance when P-51 = 0. Autotune is not required if P-51 = 1. For settings 2 – 5 of P-
51, autotune MUST be carried out AFTER all other required motor settings are entered.
Setting Function
Description
0
Disabled
1
Enabled
When enabled, the drive immediately measures required data from the motor for optimal operation. Ensure
all motor related parameters are correctly set first before enabling this parameter.
P-53

mH
Determined by Autotune, adjustment is not normally required.
P-58
DC Injection Speed
0.0
P-01
0.0
Hz / RPM
Sets the speed at which DC injection current is applied during braking to Stop, allowing DC to be injected before the drive reaches
zero speed if desired.
P-59
DC Injection Current
0.0
100.0

%
Sets the level of DC injection braking current applied according to the conditions set in P-32 and P-58.

0 : Disabled
1: Enabled.
When enabled, the drive calculated motor overload protection information is retained after the mains power is removed
from the drive.
Index 2 : Thermal Overload Limit Reaction
0
1
0
1
0: It.trp.
When the overload accumulator reaches the limit, the drive will trip on It.trp to prevent damage to the motor.
1: Current Limit Reduction.
When the overload accumulator reaches 90% of, the output current limit is internally reduced to 100%
of P-08 in order to avoid an It.trp. The current limit will return to the setting in P-54 when the overload accumulator reaches 10%
