VACON® 3000
Application Guide
• INU application: P3.4.4.3
Use this parameter to set the output frequency at which the DC-braking starts.
See 7.95 (ID 514) Prohibit Frequency Range 3 High
7.97 (ID 516) Start Magnetizing Time
Location in the menu:
• INU application: P3.4.3.2
Use this parameter to set the time during which the DC current is fed to the motor before the acceleration starts.
7.98 (ID 517) Start Magnetizing Current
Location in the menu:
• INU application: P3.4.3.1
Use this parameter to set the DC current that is fed into the motor at the start. If the value of this parameter is set to 0, the Start
Magnetizing function is disabled.
7.99 (ID 518) Ramp Time Factor
Location in the menu:
• INU application: P3.7.7
Use this parameter to set the multiplier of the selected ramp times when the output frequency of the drive is between the prohibi-
ted frequency limits. The Ramp Time Factor sets the acceleration and the deceleration time when the output frequency is in a pro-
hibited frequency range. The value of the Ramp Time Factor is multiplied by the value of P3.4.1.2 (Acceleration Time 1) or P3.4.1.3
(Deceleration Time 1). For example, the value 0.1 makes the acceleration/deceleration time ten times shorter.
