When standby mode is enabled by setting P-48 > 0.0, the drive will enter standby following a period of operating at minimum speed
(P-02) for the time set in P-48. When in Standby Mode, the drive display shows
, and the output to the motor is disabled.

%
When the drive is operating in PI Control Mode (P-12 = 5 or 6), and Standby Mode is enabled (P-48 > 0.0), P-49 can be used to define
the PI Error Level (E.g. difference between the setpoint and feedback) required before the drive restarts after entering Standby
Mode. This allows the drive to ignore small feedback errors and remain in Standby mode until the feedback drops sufficiently.

. 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.
This parameter can be used to optimise the performance when P-51 = 0.
Autotune is not required if P-51 = 1.
For settings 2

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%
