After the Stop command, the speed of the motor is decelerated according
to the set deceleration parameters.
If the regenerated energy is high it may be necessary to use an external

time.
2.4 I / O START STOP LOGIC
Values 0...4 offer possibilities to control the starting and stopping of the AC
drive with digital signal connected to digital inputs. CS = Control signal.
The selections including the text 'edge' shall be used to exclude the possibility
of an unintentional start when, for example, power is connected, re-connected
after a power failure, after a fault reset, after the drive is stopped by Run Enable
(Run Enable = False) or when the control place is changed to I / O control.
The Start / Stop contact must be opened before the motor can be started.
I/O stop logic uses accurate stop mode.Accurate stop mode is that the stop
time is fixed from falling edge of DI to power stopping the drive.
