P3.2.5 STOP FUNCTION (ID 506)
Selection

Selection name
Description
0
Coasting
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.
1
Ramp
After the
Stop
command, the speed of the motor is decreased to zero speed according
to the deceleration parameters.
NOTE:
Ramp stop cannot be guaranteed in all situations. If ramp stop is selected and the net voltage changes by
more than 20%, the voltage estimation fails. In such case, ramp stop is not possible.
P3.2.6 I/O START/STOP LOGIC (ID 300)
You can use this parameter to control the start and stop of the drive with the digital signals.
The selections can include the word 'edge' to help you prevent an accidental start.
An accidental start can occur, e.g., in the following conditions:
• When you connect the power.
• When the power is connected again after a power cut.
• After you reset a fault.
• After Run Enable stops the drive.
• When you change the control place to I/O control.
Before you can start the motor, you must open the Start/Stop contact.
In all the examples of the next pages, the stop mode is coasting, CS = Control signal.
