10.254 (ID 519) Flux Braking Current
Location in the menu: P2.4.13 (Standard Application, Local/Remote Control Application, Multi-step Speed Control Application, PID
Control Application, Multi-purpose Control Application, Pump and Fan Control Application)
Use this parameter to set the current level for the flux braking.
The value setting range depends on the used application.
10.255 (ID 520) Flux Braking
Location in the menu: P2.4.12 (Standard Application, Local/Remote Control Application, Multi-step Speed Control Application, PID
Control Application, Multi-purpose Control Application, Pump and Fan Control Application)
Use this parameter to enable Flux Braking. You can use flux braking as an alternative to DC-braking. Flux braking increases the brak-
ing capacity in conditions where extra brake resistors are not necessary.
When braking is necessary, the system decreases the frequency and increases the flux in the motor. It increases the capacity of the
motor to brake. The motor speed is controlled during braking.
C A U T I O N
Flux braking converts energy into heat and can damage the motor.
Use the braking only intermittently.
10.256 (ID 521) Motor Control Mode 2
Location in the menu:
P2.6.12
(Multi-purpose Control Application)
Use this parameter to set the AC drive control mode.
The used mode is determined with parameter
ID 164 .
For the selections, see parameter ID 600 .
Motor control mode cannot be changed from Open Loop to Closed Loop and the opposite way while the drive is in RUN state.
10.257 (ID 530) Inching Reference 1
Location in the menu: P2.2.7.27 (Multi-purpose Control Application)
Use this parameter to select the digital input signal that activates the inching reference.
The inputs also start the drive when activated and if there is no Run Request command from anywhere else.
Negative reference is used for reverse direction (see parameters
ID 1239 and ID 1240 ).
The parameter is available for VACON
®
NXP drives only.
