VACON® 3000
Application Guide
7.101 (ID 520) Flux Braking
Location in the menu:
• INU application: P3.4.5.1
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.
Use the braking only intermittently. Flux braking converts energy into heat and can damage the motor.
7.102 (ID 524) Start Delay
Location in the menu:
• INU application: P3.2.9
Use this parameter to set the delay between the start command and the actual start of the drive.
7.103 (ID 530) Jogging Reference 1 Activation
Location in the menu:
• INU application: P3.3.6.2 and P3.5.1.28
Use this parameter to set the digital input signals for the Jogging function activation. This parameter gives the digital input signal
that is used to set the frequency reference for Jogging function and make the drive start. It is possible to use this digital input signal
only when Enable DI Jogging is active.
If both Enable DI Jogging and this digital input are activated, the drive starts.
If the 2 activation signals are active at the same time, the drive stops.
7.104 (ID 531) Jogging Reference 2 Activation
Location in the menu:
• INU application: P3.3.6.3 and P3.5.1.29
Use this parameter to set the digital input signals for the Jogging function activation. This parameter gives the digital input signal
that is used to set the frequency reference for Jogging function and make the drive start. It is possible to use this digital input signal
only when Enable DI Jogging is active.
If both Enable DI Jogging and this digital input are activated, the drive starts.
If the 2 activation signals are active at the same time, the drive stops.
7.105 (ID 532) Enable DI Jogging
Location in the menu:
•
INU application: P3.3.6.1 and P3.5.1.27
Use this parameter to enable the jogging commands from digital inputs. This parameter gives the digital input signal that is used to
enable jogging commands from digital inputs. This signal does not affect the jogging commands that come from Fieldbus.
Use the Jogging function to override the normal control momentarily. Use this function, for example, to control the process slowly
to a special status or position during maintenance. There is no need to change the control place or other parameters.
