The following parameter is only available in FC 302:
Parameter 14-16 Kin. Back-up Gain
l
Parameter for configuring the monitoring and handling of a mains failure. If a mains failure appears, the drive tries to continue in a
controlled way until the power in the DC link is exhausted.
14-10 Mains Failure
Default value: –
Setup: All setups
Data type: Uint8
When parameter 1-00 Configuration Mode is set to [2] Torque, the following options are inactive:
[1] Ctrl. ramp-down
l
[2] Ctrl. ramp-down, trip
l
[5] Kinetic back-up, trip
l
[7] Kin. back-up, trip w recovery
l
This parameter cannot be changed while the motor is running.
Parameter 14-10 Mains Failure is typically used where short mains interruptions (voltage dips) are present. At 100% load and a short
voltage interruption, the DC voltage on the main capacitors drops quickly. For larger drives, it only takes a few milliseconds before the
DC level drops to about 373 V DC, and the IGBTs cut off and lose the control of the motor. When mains is restored, and the IGBTs start

Description
Use this setting for standard motors.
Updates the PWM pattern twice per switch period. Select this
option to achieve a more optimal sinus-wave and slight increase
of the output voltage.
