Ramp stop cannot be guaranteed in all situations. If ramp stop is selected and the net voltage changes over 20%, the voltage
estimation fails. In such case, ramp stop is not possible.
7.88 (ID 507) DC Brake Current
Location in the menu:
• INU application: P3.4.4.1
Use this parameter to set the current that is fed into the motor during DC braking. If the value of this parameter is set to 0, the DC
brake function is disabled.
7.89 (ID 508) DC Braking Time at Stop
Location in the menu:
• INU application: P3.4.4.2
Use this parameter to set the braking is ON or OFF and to give the braking time when the motor stops. If the value of this parameter
is set to 0, the DC brake function is disabled.
7.90 (ID 509) Prohibit Frequency Range 1 Low Limit
Location in the menu:
•
INU application: P3.7.1
Use this parameter to prevent the drive operating on the prohibited frequencies.
In some processes, it can be necessary to avoid some frequencies because they make problems of mechanical resonance. With the
Prohibit frequencies function, it is possible to prevent the usage of these frequencies. When the input frequency reference increa-
ses, the internal frequency reference stays at the low limit, until the input frequency reference is above the high limit.
With this parameter, it is possible to set limits for the "skip frequency" region.
7.91 (ID 510) Prohibit Frequency Range 1 High Limit
Location in the menu:
• INU application: P3.7.2
Use this parameter to prevent the drive operating on the prohibited frequencies. In some processes, it can be necessary to avoid
some frequencies because they cause mechanical resonance.

Description
The drive accelerates from 0 frequency to frequency reference.
The drive detects the actual speed of the motor and accelerates from that speed to fre-
quency reference.
Description
The motor stops on its inertia. When the stop command is given, the control by the drive
stops and the current from the drive goes to 0.
After the stop command, the speed of the motor is decreased to zero speed according to the
deceleration parameters.
